This gifted group of engineers rated craftsmanship and quality of
materials as fundamental in loudspeaker design. The newly founded Castle Acoustics decided to go
its own way and manufacture each Castle loudspeaker to the finest furniture-quality standard using
the most sought after woods and veneers allied to the most advanced acoustic materials and
technology of the time.
Now part of the International Audio Group, and under the watchful eyes of Chief Engineer, Steve
Hewlett, Castle Acoustics faces a bright future. The new Classic series re-establishes Castle
products at the very cutting edge of research into acoustics, while retaining the traditional virtues
of impeccable design and presentation – a perfect balance of form and function.

Foreword
Before connecting and using your loudspeakers, please bear the following points in mind:
CS
Switch off the amplifier and all sources before making connections to your sound system. When you switch on
#
the system or change sources, set the volume control to minimum and turn up the level gradually.
The position of your Volume Control is NOT a reliable guide as to the maximum capabilities of your sound system.
#
LASSIC ERIES
Playing the systemwith extremesettings of volume andtone controls may damagethe amplifier and loudspeakers.
Do not connectloudspeakerterminals tothe mains supply.
#
Ensure that yourloudspeakers are correctly wired and arein phase.
#
Do not subjectyour loudspeakersto excessivecold, heat orsunlight.
#
If you are shelf mounting your loudspeakers, make sure they are not placed on the same shelf as your source
#
components.
Do not place heavy objects on top of loudspeaker cabinets. If you play the loudspeakers with the grilles removed be
#
careful to protectthe driveunits from children andpets.
Do not use makeshift stands. Always fit a manufacturer's approved stand using the instructions and the fixings
#
provided. Yourdealer will adviseyou.
Do not attempt to dismantle the loudspeaker. There are no user serviceable parts inside and you will invalidate the
#
warranty.
Some Front and all Centre loudspeakersare magnetically screened. You should site front loudspeakers at least 0.5 m
#
away from TV sets and magnetic storage media. AllCastle centreloudspeakers may be sited close to aTV screenwith
no adverse effects. The specificationson Pages 20 and21 have AV shielding detailsfor yourloudspeakers.
When connecting your loudspeakers, do not run cable across areas of open floor where they may be a source of
#
danger. Run them safely, aroundroom boundaries if necessary.
Final Thoughts
Looking After Your Loudspeaker
#
Your Castle Loudspeakers use a specially hardwearing sealed finish. They should bot be waxed or treated with
spray polishes which will smear and dim their lustrous finish.. Occasionally polish them with a dry or barely
moist cloth to remove dust and finger marks, etc.
Occasionally, remove the loudspeaker grilles and brush them gently with a soft brush before replacing them
#
carefully.
Never stand objects on your loudspeakers. In particular do no stand flowers atc on them - they are not
#
jardinieres!
##Avoid getting any liquid behind the grille. If you accidentally spill liquid on your loudspeakers, take them to
your dealer for attention before using them again.
Do not open the speakers; there are no user serviceable parts inside. Never touch the drive units either with
an object or your hands.
Quality Assurance
Your Castle loudspeakers have been constructed to the highest standards. From the top grade furniture
construction and finish to the carefully designed and selected acoustic components, the Castle range is a
testament to fine design, fine engineering and fine craftsmanship. Our speakers are built to provide a lifetime of
pleasure to the eye, the ears and through the music they play, the soul. We hope you will derive many years of
good service from our products.

Delay and LFE Settings
The purpose of delay is to enable surround and dialogue information to arrive at the listener’s ears at the same
CS
LASSIC ERIES
time as the Front channels, even when the listening seat is in a non-ideal position.
Rear Delay: If the listening position is equidistant from the Front and Rear speakers, a low delay setting should be
set. The closer the listener is to the Rear speakers the higher should be the delay setting used,
Centre Delay: If the Centre speaker is level with (or slightly behind) the Front speakers, set the delay to zero. If
the Centre speaker is forward of the Front speakers, increase the delay.
LFE: In domestic systems the LFE channel typically feeds into the subwoofer. Where no subwoofer is used, the
LFE signal is combined with Front Channel information. When you set the LFE level at your AV processor, use
care as the powerful low frequencies can overload domestic loudspeakers.
If you hear popping or thumping noises coming from the front loudspeakers or subwoofer, immediately turn the
AV Processor's volume level down and then back off the LFE level. This should cure the problem. If it does not,
back off the volume level at the subwoofer (if you are using one) until the problem disappears.
Please read the relevant sections of your AV amplifier manual and familiarise yourself with the various issues. If
you are unsure, consult your dealer for help.
Expanding the System
Dolby Labs, DTS and THX offer 6.1 and 7.1 formats. Although the precise configuration of these systems will
depend on the capabilities of your processor and you should be guided by those instructions, we would make
some observations.
For most 6.1 and 7.1 formats, and especially Dolby ES, the listening seat should not be too close to the rear wall.
Optimising the time delay so that information from all speakers arrives at the listening seat coherently is critical if
the benefits of these systems are to be fully realised.
Dolby Labs Recommended 7.1 Placement
Unpacking Your Loudspeakers
#
Castle loudspeakers come in many shapes and sizes. Now you have opened the carton, we hope you are reading this
manual.
If you are unpacking the larger loudspeakers or the Classic Subwoofer, please remember that these units are heavy. We
#
suggest that you have someone to assist you.
Lift the loudspeaker carefully out of the packing. Do NOT try and lift the loudspeaker using the cloth bag.
#
Unpack any accessories carefully. The larger loudspeakers will need to be assembled on their plinths and spike kits.
#
If there is any sign of damage or if the contents are incomplete, report this to your dealer as soon as possible.
#
Retain the packing for future safe transport of the product. If you dispose of the packing, do so with respect to any
#
recycling provisions in your area.
Stand mounting and AV loudspeakers are ready to be connected after unpacking.

Setting Up a Home Theatre System
Some of this chapter may appear to repeat the content of the Subwoofer pages - the context however is different.
Choosing Loudspeaker Cable
Specialist audio cable usually offers better performance than general purpose ‘bell’ or
‘zip’ wire.
CS
LASSIC ERIES
Choose a cable of suitable diameter – cable that is too thin will limit the dynamics of
the sound and may impair the bass response. Audio cable is polarised, with two cores of
different colours, or often a raised rib or coloured tracer in the case of twin cable.
Before you purchase your cable, we suggest that you give careful thought to the
positioning of your loudspeakers. This is especially the case if you are bi- or tri-wiring
your loudspeakers.
Cable lengths to loudspeaker pairs should be the same for left and right channels in
order to equalise the signal transmission. Allow some slack in your speaker cables so you
can alter their position to best advantage, but do not have your cables over-long.
Preparing Loudspeaker Cable
Split the twin cores to a depth of about 40mm. Carefully strip the insulation from each
end, leaving about 10mm of bare wire. If the cable is stranded, lightly twist to gather
any loose strands.
10mm
Placement
Front And Effects Channels
The front loudspeakers are placed on either side of the television screen, 2 to 3 metres apart. The speakers should be angled
slightly so they are aimed towards the listeners.
We recommend placing the rear effects speakers in a high position, behind the listener’s head. If the rear or side walls are a
long way from the listening seat, consider stand mounting the loudspeakers. If the centre loudspeaker is very high or low,
angle it towards the listener's ear level. The front faces of the centre and surround loudspeakers should also be in line as far
as possible. Note the special position for the Castle Oriel.
Subwoofer
As the ear is unable to detect the direction from which deep bass originates, this allows you freedom to position the unit.
Varying the distance from the wall alters the bass. Placing the subwoofer across a corner boosts the bass but may impair
clarity. The performance of Home Theatre systems can often be enhanced by using a pair of subwoofers.

Connecting Screw Terminals
All the Castle loudspeakers use screw terminals.
Safe Connection of Terminals
Unscrew the terminal. Insert the bare end of
the cable into the hole in the base of the
terminal. Tighten securely.
When connecting terminals make sure you
leave no strands of bare wire that can short
across to adjacent terminals.
As an alternative to bare wire you can use
specialist spade connectors. Your Castle
dealer will be pleased to advise you.

Setting Loudspeaker Sizes
Many digital AV Processors ask you to specify the size of speakers in all channels - usually ‘Large’ or ‘Small’.
The Floor standing Castle loudspeakers may be safely set to 'Large'. The other loudspeakers should be set to ‘Small’
If you are not using a subwoofer: Set the Front Speakers to ‘Large’. Set the ‘Subwoofer’ option on the processor to 'Off' or
‘No'. The Front channels will now receive all the system bass.
If you are using a subwoofer: When set to ‘Small’ all the system bass will go into the subwoofer. If you choose ‘Large’ the
Front channel bass will be reproduced from the Front speakers.
Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode (see instructions supplied with
your processor). Adjust the level of each channel until all channels are reproduced at equal loudness.
You may need to adjust the subwoofer output level. Avoid setting too high a level or you will swamp the sound with bass and
may limit the subwoofer’s ability to respond to large bass transients. You should also set a sensible level going into the
subwoofer from the AV processor.

Fine Tuning Procedures
Crossover Networks
Setting up of the subwoofer should be performed with all tone controls and filters on your amplifier or processor set ‘ flat’.
Listening rooms are not ideal. Because of room geometry and construction there will be areas with severe peaks at some
frequencies and severe troughs at others. If you site loudspeakers in such areas the response will be highly non-linear. It is
easier to treat high frequency irregularities by the use of drapes, soft furnishings etc., but very hard to do the same at bass
frequencies due to the very long wavelengths.
CS
To help locate standing waves in your listening room, one idea is to sit in the listening seat and recruit a friend with a deep
voice to speak as he moves around the area where you propose to site your subwoofer - you will soon find out where to
site it! Where the voice sounds most natural is a good place to start.
LASSIC ERIES
Although the subwoofer's bass output is enhanced by walls or corners, so often is coloration. The floor will influence the
sound. The surface under the subwoofer should be stable and unobstructed. If the carpet is very thick, consider placing the
subwoofer on a solid surface such as a marble slab. If you place the subwoofer where it amplifies the irregularities of the
room or the main speakers the result will be bloated, coloured bass. If acoustic guitar and male voice sounds coloured when
the subwoofer is operating at normal level and less coloured if the subwoofer volume is reduced, you need to address the
positioning first before adjusting any controls.
Loudspeaker Phasing:
the loudspeakers are connected, check their phasing by playing a mono source - the sound should appear from a point
midway between the front loudspeakers. If this position is indefinite, reverse the connections to one speaker. Correctly
connected loudspeakers give a definite centre sound source with fuller bodied tenor and bass registers.
Setting the Phase of the Subwoofer:
temporarily set the low pass filter to ‘off’ and the phase to 0º and play some bass heavy music in Stereo through the main
speakers and the subwoofer. From the listening position, switch the phase between 0º and 180º. The setting which appears to
give the greater bass output is correct. Now follow the instructions below for setting the low pass filter.
Crossover Control:

Castle loudspeakers use a variety of terminal panels. These fall into three types.
Biwireable Crossovers
A bi-wiring panel has four terminal binding
posts. The upper terminals connect to the
treble units, the lower pair to the bass unit.
As supplied the treble and bass terminal
pairs are connected via removeable straps.
This arrangement facilitates standard single
wiring, and advanced bi-wiring which offers
significant performance advantages. Follow
the drawings carefully to see the correct
orientation of the loudspeaker terminals.
Why Bi-Wire?
Bi-wiring involves the use of two separate
cables between the amplifier and the
loudspeakers. One pair connects to the
treble unit the other to the bass driver.
Using separate cables for treble and bass
units in a Bi-Wiring configuration reduces
intermodulation effects and improves
headroom and clarity. To bi-wire, you will
need to install two lengths of twin core
cable between the amplifier and each
loudspeaker.

Setting Loudspeaker Sizes: Most digital AV Processors ask you to specify the size of speakers in the various channels. These
are usually ‘Large’ or ‘Small’. This sets the bass management for the system. Castle floor standing loudspeakers can be set to
'Large' Smaller loudspeakers (including stand mounted units) should be set to 'Small' for the Front channels. Choose 'Small'
for the surround channels and also for the Centre channel, so that any bass from these channels will be directed to the
subwoofer. Set the ‘Subwoofer’ option on the processor to 'On’ or 'Yes'.
After experimenting with various sources you may need to adjust the Subwoofer Crossover settings. Try to ensure the
subwoofer blends into the sound stage - the more invisible the subwoofer component of the sound field is, the better.
Setting levels:
Once the loudspeaker settings have been finalised, put the AV amplifier into its “Test” mode (see instructions supplied with
your processor.) Adjust the levels until all channels are reproduced at equal loudness.
When adjusting the subwoofer output level avoid setting too high a level or you will swamp the sound with bass which be
tiring to listen to and may limit the subwoofer’s ability to respond to large bass transients. Set a sensible level going the
subwoofer from the processor.
LFE: This channel was originally an additional bass channel with its own dedicated subwoofer. In practice however, if any
speakers are set to ‘Small’, the LFE channel is combined with the bass from those channels and fed into the subwoofer.
When you set the LFE level from your AV processor, use care as the LFE channel contains powerful low frequencies which,
although normal in a cinema, may overload a domestic subwoofer. If, during a programme, you hear popping or thumping
noises from the subwoofer, turn the AV Processor volume level down and back off the LFE level. If this does not cure the
problem, lower the subwoofer volume level.

Standard Crossovers
The Richmond Classic 3i and Oriel use
standard crossovers.
The Oriel uses a special version built into
the rear wall of the loudspeaker.
Castle Howard
The Howard uses separate terminal panels
for the treble and bass sections of the
loudspeaker. We recommend that the
Howard should only be bi-wired.

If the loudspeakers are placed too close to the walls the bass will increase but may be boomy and indistinct. If the
loudspeakers are placed further away from the walls, the inward angle ("toe in") may be increased by up to 30% As personal
taste plays a large role, experiment with different configurations and play a wide range of programme material before finalising
the position of your speakers.
The optimum listening position is in the area broadly known as the ‘sweet spot’. The more extreme the angle the narrower the
sweet spot is. Castle loudspeakers are designed to cover a medium sonic perspective so there should be no need fo extreme
settings.

Stand Mounting Loudspeakers
The Castle Durham, Warwick and Richmond 3i are designed for stand mounting.
The stands should be sturdy and offer optimum support for the loudspeaker. As an
alternative the speakers may be wall mounted on rigid brackets or placed on rigid
shelves.
Ideally the top of the speaker should be at ear level to a seated listener. If the rear
panels of the speakers are placed close to the walls the amount of bass will be
increased but the clarity may well suffer - you should experiment until you get the
best result.

loudspeakers, the lower settings for large floorstanding models. If you choose too low a setting with small speakers,
there will be a ‘hole’ in the bass response; too high a setting with large speakers will result in the upper bass

When the system is not in use for extended periods, we suggest you switch off the subwoofer to protect it from
switching noises caused by domestic appliances, etc. The best practice is to switch the complete system on and off
from a central point. Bear in mind that if you play the system with the subwoofer switched off you will get no
bass!
Always turn the main volume control to minimum when you switch the system on or off.

Positioning Castle Classic AV Speakers
Front Loudspeakers: The front loudspeakers are placed on either side of the TV monitor, 2 to 3
metres apart. The speakers should be angled slightly so they are aimed towards the listeners.
Rear Surround channels: The reproduced sound should be as room filling as possible. We
recommend placing the speakers in a high position, behind the listeners head. If the rear wall is
more than 1 metre behind the listening seat, an alternative position is on the side walls. If the walls
are a long way from the listening seat, consider stand mounting the loudspeakers.
Centre Channel: Most of the dialogue comes from the centre loudspeaker. Speech should appear to
originate from the actors mouths. Operating height is important. Ideally the front and centre
channel speakers should be at the same height. The front of the cabinet should be level with the TV
screen.
The Castle Bastion and Keep centre channel loudspeakers may be mounted on a shelf or placed on
top of the TV cabinet if it is safe to do so.
The Castle Oriel is designed for wall mounting. The unique design of this loudspeaker enables its
use either on the rear or the side walls of the room presenting both direct and ambient reflected
sounds

Connecting to a Digital AV Processor
If your AV processor has a line level or LFE subwoofer
output you should use this connection. You will need to
purchase a single screened RCA phono lead from your
dealer. Connect this lead to the Left line input of the
Subwoofer as shown.
Alternatively, you may use a split mono lead from the
processor to both inputs of the subwoofer. In this case
the input level at the subwoofer will be slightly higher.

The Castle Classic Subwoofer
Introduction
The Castle Classic subwoofer is intended for use with high quality domestic sound reproducing. Your subwoofer
will probably be used in conjunction with Castle loudspeakers though it will partner any audiophile or top-quality
home cinema amplification and loudspeakers.
Unpacking the Subwoofer
Open the carton and remove all the top packing pieces. Lift the subwoofer out taking care not to damage the
cabinet. When lifting the unit from the carton support it from the bottom. DO NOT attempt to lift the
subwoofer out of the carton using the cloth bag. The unit is heavy; if you cannot manage it easily, get someone to
assist you.
Positioning the Subwoofer
Although the unit may be placed almost anywhere in the room, we recommend that it be placed in front of the
listener and as central to the listening position as possible. There should be a mains outlet within easy reach. The
subwoofer should not be operated within 450mm of a television set as the drive unit magnet may distort the
picture. Remember that there should be a line of sight between the listening position and the front of the
subwoofer otherwise the handset remote functions will not be operable.
We suggest you initially position the subwoofer about 20cm (8 inches) from the wall. Placing the unit close to the
wall will enhance the bass; placing it across the corner of the room will increase the bass further, possibly at the
expense of clarity. Do not place the subwoofer close to surfaces or objects that may rattle. The floor under the
subwoofer should be sound with no loose floorboards, etc. Experiment with locations and sources before making
a final decision.

Before Connecting the Subwoofer
#
Level the subwoofer taking care to make sure it sits squarely on all its spikes. To protect sensitive floors a set
of spike seats is provided. Refer to Page 3 for instructions on levelling the speakers and the use of spike
seats.
#
Switch off your amplifier and all connected source units at the mains.
#
Unplug the power cords to all system components if necessary
#
Make sure the subwoofer is disconnected from the mains and that the ON/OFF switch is OFF
#
Before re-connecting your system to the AC power supply, check that all the connections are properly made
#
Check that all speaker terminals are done up tightly.
#
Ensure that there are no strands of wire shorting adjacent speaker terminals
#
Signal cables should be properly terminated and fully screened to minimise hum. If you connect your
subwoofer via the low level signal inputs, the cable between your control unit or processor and the subwoofer
could be quite long so screening is particularly important. Consult your dealer if in doubt
