Location

Here is a neat trick to find the best subwoofer location for your room:

1.Start by placing it right on the seat of your favorite couch or easy chair. (This method is odd, but it is based on principles of acoustic physics).

2.If the subwoofer is part of a Home Theater system you can use the calibration test tone (pink noise) usually found in the processor/ receiver's setup menu; or you can simply plug the outputs from a CD player directly into the subwoofer’s line-level inputs, remembering to turn down the volume level on the subwoofer first, and then play- ing some of your favorite music samples containing heavy bass.

3.Walk around the room listening. Stand in all the locations where you might place the subwoofer. Try crouching down, particularly in the corners. Find the place where the subwoofer’s bass output sounds the loudest.

4.Turn off the subwoofer and discon- nect it from the power and from your processor/receiver or CD player. Next, install the subwoofer in the location you have just deter- mined is best and remake all your connections.

Although low frequencies are non-di- rectional, factors such as room reflec- tions, standing waves, resonance and ab- sorption will strongly affect your subwoof- er’s performance. Moving the subwoofer from one location to another can have a major effect on the bass response.

Magnetic Fields

Remember to keep the subwoofer at least two or three feet away from

any TV screen, computer, VCR or magnetic tapes and discs. This will reduce the chance of the magnetic fields

upsetting the TV screen or erasing your magnetic media.

Using two Subwoofers

If you wish to use two subwoofers, the sound output will double (an increase of 6 dB). Locate the subwoofers with one in each corner and experiment with the location and phase control to achieve the best bass response.

Always drive each subwoofer through the left line-level input even though you are driving one subwoofer with a right channel drive and the other with a left channel drive. If your preamplifier has a single sub/LFE output, use a Y cable to split it into two outputs.

The HRS-8, with its 8-inch driver, is designed for those who desire quality sound in a more compact form factor. Despite its smaller size, this subwoofer is powered by a 600-watt peak amplifier and delivers surprisingly deep bass. Ideal for smaller rooms or setups that need discreet audio solutions, the HRS-8 still excels in performance, making it a favorite for apartment dwellers or those with limited space.

All models in the Sunfire HRS series incorporate advanced features such as adjustable phase control, variable crossover frequencies, and a front-firing design that allows for flexible placement options.
