1. Introduction

The Tannoy VS10BP is a compact, versatile subwoofer system, designed to
extend the low frequency response of the V series loudspeakers and increase
system headroom.
The VS10BP will extend the frequency response of these systems to below 40Hz
and is capable of providing output levels normally be associated with considerably
larger enclosures.

The VS10BP comprises one high efficiency 250mm(10”) drive unit. The compact
dimensions of the V10BP enable it to be used in applications without being
obtrusive, such as underneath seating and bars. M10 rigging points are also
provided to allow permanent installation. Versatility is further enhanced by the
introduction of blanking plates, which allow the bass ports to be moved to another
face of the cabinet allowing installation in various orientations.

2. Unpacking

Every Tannoy VS10BP is carefully inspected before packing. After unpacking your
loudspeaker, please inspect for any exterior physical damage, and save the
carton and any relevant packaging materials in case the loudspeaker again
requires packing and shipping. In the event that damage has been sustained in
transit notify your dealer immediately.

3. Connectors/Cabling

Cable choice consists mainly of selecting the correct cross sectional area in
relation to the cable length and the load impedance. A small cross sectional area
would increase the cables series resistance, inducing power loss and response
variations (damping factor).

Connectors should be wired with a minimum of 2.5 sq. mm (12 gauge) cable. This
will be perfectly satisfactory under normal conditions. In the case of very long
cable runs the wire size should exceed this, refer to the following table for
guidance:-

The VS10BP is fitted with two pairs of 4mm binding posts (Fig1) for the amplifier
input and highpass output connectors to the satellite loudspeakers. An external
active crossover such as the TDX1 or TDX2 is not necessary but will increase the

versatility of the system allowing relative attenuation between the subwoofer and
satellite loudspeakers and provide delay if required as well as driver protection
and optimal integration.

4. System Configurations.

Configuration 1.

The most basic configuration would be a VS10BP and up to two-8ohm satellite
amplifier. The ‘performance data’ section of this manual shows the impedance
presented to the amplifier with one and two V8 (8ohm) loudspeakers.

Configuration 2.

A TDX1/TDX2 or other OEM system controller can be used to further enhance
and increase the flexibility of the system. A system controller will allow the relative
levels of the satellites and VS10BP to be adjusted separately. Limiters, delay and

optimal crossover points are also afforded by the introduction of a system
controller.
A loudspeaker driven actively as shown below offers a number of other
performance advantages, such as increased system headroom. Audio program
materiel is made up of many different frequencies and harmonics. In music
materiel, most of the energy is in the low frequencies, with less in the highs. When
both high and low frequencies are present in a signal, the stronger low
frequencies can use up amplifier power, leaving little or no reserve for the highs,
so they are more likely to cause the power amplifier to clip. In an active driven
system, a smaller amp can handle high frequencies, LF amp clipping is less of a
factor, and less overall amplifier capacity is needed due to the efficiency
improvement in the absence of a passive crossover.

5. Amplification & Power Handling

As with all professional loudspeaker systems, the power handling is a function of
voice coil thermal capacity. Care should be taken to avoid running the amplifier
into clip (clipping is the end result of overdriving any amplifier). Damage to the
loudspeaker will be sustained if the amplifier is driven into clip for any extended
period of time. Headroom of at least 3dB should be allowed. When evaluating an
amplifier, it is important to take into account its behaviour under low impedance

load conditions. A loudspeaker system is highly reactive and with transient signals
it can require more current than the nominal impedance would indicate.

Generally a higher power amplifier running free from distortion will do less damage
to the loudspeaker than a lower power amplifier continually clipping. It is also
worth remembering that a high powered amplifier running at less than 90% of
output power generally sounds a lot better than a lower power amplifier running at
100%. An amplifier with insufficient drive capability will not allow the full
performance of the loudspeaker to be realised.

It is important when using different manufacturers’ amplifiers in a single installation
that they have very closely matched gains, the variation should be less than +/-

0.5dB. This precaution is important to the overall system balance when only a
single active crossover is being used with multiple cabinets; it is therefore
recommended that the same amplifiers be used throughout.

6. Equalisation/Placement

The VS10BP is designed to need no equalisation or correction to overcome
system limitations. As a result, it will only need equalisation to compensate for
difficult acoustic environments.

Excess equalisation can reduce system headroom, and introduce phase distortion
resulting in greater problems than it cures. If equalisation is required then it should
be applied gently and smoothly. Violent equalisation will be detrimental to the
overall sound quality.

The frequency band over which a subwoofer operates is essentially omni­directional, therefore efficiency of the VS10BP may be further enhanced if the unit
is placed against a wall, where the radiation in the forward plane will be doubled
due to the addition of the reflected rear directed energy, and a 3dB increase in
sound pressure will occur. If another boundary is introduced, say a floor, then the
effective radiation space is halved again, resulting in a further 3dB lift, and if
placed in a corner, once again the sound pressure level will increase by a further
3dB.

The compact dimensions of the VS10BP allow the VS10BP to fit into small
spaces. A unique feature incorporated into the VS10BP further enhances this
flexibility;

The Bass Ports on the VS10BP can be moved onto the other face of the cabinet
as shown below. Simply remove the blank plates and Bass ports and swap
positions. Each chamber in the enclosure utilizes a different length bass port. To
avoid placing the wrong Bass port in the wrong chamber the holes in the
enclosure are ‘Keyed’.

The features described above allow the VS10BP to be placed in any orientation.

Tannoy operates a policy of continuous research and development. The introduction of new materials or manufacturing

methods will always equal or exceed the published specifications which Tannoy reserve the right to alter without prior

notice. Please verify the latest specifications when dealing with critical applications.

10. Rigging & Suspension

General Safety Advice

WARNING: As the legal requirements for flying change from country to country,

please consult you local safety standards office before installing any product. We

also recommend that you thoroughly check any laws and bylaws prior to

commencing work. Qualified personnel trained in safe rigging practices should

only suspend the system.

Whenever a Tannoy Professional loudspeaker is fixed to a surface using a

Tannoy

Professional hardware device, the installer must ensure that the surface is

capable of safely and securely supporting the load. The hardware employed must

be safely and securely, attached both to the loudspeaker and also to the surface

in question, using only the fixing holes provided. Secure fixings to the building

structure are vital. Seek help from architects, structural engineers or other

specialists if in any doubt.

All loudspeakers flown in theatres, nightclubs, conference centre or other places

of work and entertainment must, be provided with an independent, correctly rated

and securely attached secondary safety – in addition to the principle hardware

device. This secondary safety must prevent the loudspeaker from dropping more

than 150mm (6”) should the principle hardware device fail.

Threaded inserts are fitted to the VS10BP to allow the suspension of a single

enclosure. Never suspend one enclosure from another to form an array or cluster

using only these fittings.

If eyebolts are being used then only forged shoulder eyebolts should be used

with a thread length of 30mm (see section 8.3).

SECUR ET – VEB Eyebolt

7.

!

The Tannoy VS10BP loudspeaker can be
flown with high quality VEB M10 eyebolts with
collar to BS4278:1984. The loudspeaker is
equipped with internal steel braces, which also
double as the flying points, and accept VEB
M10 eyebolts.

To install the VEB M10 eyebolts remove the
original M10 counter sunk screws from the
locations you wish to install the VEB M10
eyebolts. Then replace these counter sunk
M10 screws with the VEB M10 eyebolts.

Important: It is imperative for safety reasons
that two eyebolts linked to two independently
fixed straps are used per cabinet. VEB
eyebolts should be installed into the relative
sides of the cabinet, and should NEVER be
installed on the top of the cabinet. Never
suspend one enclosure from another to form
an array or cluster using these fittings.
Never attempt to use formed eyebolts i.e.
formed from a steel rod and bent into an eye.

11. System Configurations & OEM Controllers

With the vast array of digital loudspeaker management systems available it is

inevitable that the user may opt to use a controller other than a Tannoy controller

as part of a large scale integrated system. The VS10BP has been designed to

need no external equalisation to overcome system limitations. Below is a list of

recommended parameters; these parameters can be further tailored depending
