Page 5: Overview
The Drivers To have lots of bass requires moving lots of air. Your Sunfire subwoofer incor- porates two drivers that can move back and forth approximately five times more than a normal subwoofer. This gives it a lot of air moving capacity which allows for majestic bass performance. -
Page 6: Amplifier Features
Amplifier Features 1. Standby LED and . Power Switch Press the power switch in to turn on the amplifier. As a general rule, turn it on after your preamplifier or receiver is turned on. When you have finished listening for the night, turn it off before your preamplifier or receiver. - Page 7 Rotate the crossover frequency control until the bass sounds natural. If the mid-bass sounds good but you want more low bass, turn this control down a little, then turn the Volume control up by about the same amount. This increases the low-bass output while leaving the mid-bass output the same.
- Page 8 To do this, connect 1 VDC to either of these terminals. Some Home Theater preamplifiers, such as the Sunfire Theater Grand series, have matching 1 VDC Trigger outputs. When they are turned on, the subwoofer will turn on.

Subwoofer installation Mounting options Your subwoofer has three mounting possibilities. (You will need an assistant to help lift and position the subwoofer.) A. Free standing. Two brackets are easily fitted to the subwoofer with thumbscrews. B. Vertically. The subwoofer can be fitted up against a wall, with one foot bracket on the floor. -
Page 12: Room Equalization Procedure
Room Equalization Procedure Subwoofer performance is greatly af- fected by the room in which it is situated, and the positioning within the room. The room effects will boost and cut the output levels reaching your listening position. This gives a "room EQ" effect which can often be far from wonderful. - Page 13 If you find that the first test tone plays louder and louder, and never leaves the first band, then either the microphone is too far away from the subwoofer, or it is not plugged in correctly. 8. The procedure may take several minutes.

Page 14: System Configurations
Make sure this is correctly adjusted, and that the Sunfire subwoofer’s crossover frequency is set to 100 Hz. This is by no means an iron-clad rule, rather it is a good starting point. (See the crossover frequency control details on page 6 and adjustments on page 17). - Page 15 “Top Gun”, for example, has loads of L-R bass information. If this is not preserved, the bass in these scenes sounds anemic. The Sunfire subwoofer utilizes differential gain on the left and right inputs to retain both the L+R and L-R information. Therefore,...
- Page 16 Using the line level high-pass outputs If you are using a preamplifier which does not have a sub/LFE output, you can send its left and right front output into the line-level inputs and then connect the sub amplifier’s high-pass outputs to the inputs of your main amplifier.

The vertical mounting procedure is as follows: With the help of an assistant, gently hold the subwoofer vertically.
- Page 20 Greater than 110 dB peak SPL (includes room gain) from 18 Hz to 100 Hz. Mea- surement is one meter, anechoic. A typical Sunfire subwoofer can be expected to ‘best’ its specified minimum peak SPL by several decibels. Total Harmonic Distortion Typically less than 1/10 of the funda- mental between 18 to 80 Hz.
