Introduction

Features

Thank you for purchasing a Sunﬁ re True Subwoofer Super Junior. We hope you enjoy it and the music it makes as much as we have enjoyed creating it for you.

The big breakthrough features of the subwoofer are its uncanny tracking downconverter and its long throw, high back-electromotive force driver. Taken together, they provide this sub woof er with as much bass as you could get from several 15 inch drivers mount ed in a cabinet the size of a small re frig er a tor.

Unpacking

Your Sunﬁ re Subwoofer should reach you in perfect con di tion. If you do notice any ship ping dam age, please contact your Sunﬁ re Dealer im me di ate ly.

Gently lift out the unit and remove all the packing material. It is im por tant to save all the packing ma te ri als and the box in case your subwoofer ever needs to be moved or shipped for repair.

Make sure that you keep your sales receipt. It is the only way to establish the duration of your Limited Warranty and it may come in useful for insurance pur pos es.

Please take a moment to ﬁ ll out and mail the Sunﬁ re Warranty Registration card. Also read the serial num ber located on the control panel and record it here:

• High power, high efﬁ ciency ampliﬁ er

• High gloss, dark rosewood ﬁ nish (also referred to as Deep Bing Cherry Lacquer)

• Very low distortion

• Long throw, premium quality drivers

• Extremely compact size

• Automatic signal-sensing turn-on and standby mode

• Line level unbalanced inputs

• Speaker level binding post inputs

Overview

Your Sunﬁ re Subwoofer is designed to give you the best possible low-fre quen cy sound quality for your Home Theater ex pe ri ence. It in cor po rates a tre men dous ly powerful built-in am pli ﬁ er and a pair of drivers to produce tight, ﬂ oor-rumbling bass down to 22 Hz, that you can feel as well as hear.

The subwoofer has an adjustable high cut ﬁ lter and a choice of speaker-level or line-level inputs for easy in cor po ra tion into existing systems, or as part of a subwoofer/satellite speaker com bi na tion.

Controls for adjusting the volume, crossover frequency and phase, allow the subwoofer to be perfectly matched to any listening environment and audio components.

The Drivers

To have lots of bass requires moving lots of air. Your Sunﬁ re Subwoofer incor- porates two drivers that can move back and forth ap prox i mate ly ﬁ ve times more than a normal sub woof er. This gives it a lot of air moving capacity which allows for majestic bass per for mance.

Two drivers share the acoustic output. Sometimes one driver appears to be moving more than the other. They both move the same amount only when operating at the limit of their ex cur sion and power output, or when bass requirements and music re quire ments demand maximum output from the system. Otherwise, the power is shared between the two drivers in a way that depends on the momentary am pli tude and the mo men tary musical spectrum. It is normal for one or the other to move more or less than its mate during operation.

On the driver to the right of the control panel there is a slight bump, under which is a pressure cap. The bump is normal. The driver on the left is ab so lute ly ﬂ at and very rugged. The one with the slight bump is not quite as rugged, and modest

care should be taken with it, though it is still very strong. During installation, you should position the driver with the bump towards a protected side.

The Ampliﬁ er

The large movement range of the drivers creates greater air pressure inside the box than a con ven tion al woofer. There fore, the drive am pli ﬁ er must be much more powerful than an or di nary woofer ampliﬁ er. In fact, it has to be so powerful that it is almost hard to believe.

The power ampliﬁ er within your Sunﬁ re Subwoofer is capable of de liv er ing over 1,500 watts into a 4.6 ohm resistor (the voice coil re sis tance of the subwoofer’s driver). When the same full output is applied to the driver, however, the enor mous back-elec tro mo tive force gen er at ed as a con se quence of its large motion and giant magnet causes the current ﬂ ow to be much less than if it were a 4.6 ohm resistor. It is this singular property of the driver that allows the woofer to be ap prox i mate ly ten times more efﬁ cient than a woofer this size would nor mal ly be. Hence, the actual average input power is substantially less than 1,500 watts, and is ap prox i mate ly 120 watts for most musical material on the loudest pas sag es.

A compressor circuit kicks in au to mat i cal ly if the input signal level reaches a level that would overload the driver. This maintains a ceiling on the output without clip ping. If the input signal is driven even further, a ‘soft clipping’ circuit is enabled. This allows the woofer to put more sound into the room to satiate the power hungry user, but without distortion or damage to the woofer. Thus, for explosive scenes in movies, this pro duc es extremely high sound pressure levels (SPL) in your room without the woofer banging against its mechanical stops.

Control Panel Features

1 2

FUSE

1. Bass Level

This control lets you match the output level of the subwoofer to the level of your sat el lite/main speak ers. The subwoofer output will increase as this control is rotated clockwise. When you have just installed your system, turn this down ﬁ rst before turning on your sub woof er. This will prevent any loud surprises.

2. Crossover Frequency

This controls the high frequency cutoff point. With the control set to the 100 Hz mark, the sub woof er will reproduce fre quen cies up to 100 Hz. If the control is set fully clockwise, the crossover is bypassed and the subwoofer will re pro duce a wide frequency range. With the control fully counter-clock wise the sub woof er re pro duc es a narrow range, up to 30 Hz.

Rotate the control until the bass sounds natural. If the mid-bass sounds natural but you want more low bass, turn the control down a little, then turn the Bass Level control up by about the same amount. This increases the low-bass output while leaving the mid-bass output the same.

3. Phase Control

This control changes the relative phase

of the sub woof er with respect to your

other speakers. Use this control to help

blend the sub woof er with the rest of

your sys tem. This is accomplished by

ad just ing the control in small in cre -

ments as you listen for the most bass

at your lis ten ing position. As a ﬁ nal trim,

readjust the Crossover Frequency and

Bass Level controls after the phase has

been set.

4. Outputs

Line level high-pass output signals are

available at these jacks. These outputs

are active whenever a signal is hooked

up to the inputs of the sub woof er. This

crossover is a passive network with a

ﬁ xed crossover frequency of 70 Hz and

a 6 dB per octave slope.

We rec om mend using this high-pass

function with main/satellite speak ers

that are small and not designed to

reproduce low fre quen cies. If your main

speakers are capable of op er at ing full

range, then you will not need to use the

high-pass function.
