OPERATION

Crossover Adjustments

High-Pass Control

• This control is only active if you are using the hook-up

method described in detail on page 8, Figure 3. The

High-Pass control determines the frequency at which the

main speakers will start reproducing sounds. If your main

speakers can comfortably reproduce some low-frequency

sounds, also set this control to a lower frequency setting,

between 50Hz – 100Hz. This will concentrate the

subwoofer’s efforts to the ultradeep bass sounds, while your

main speakers continue to reproduce the mid-bass

information. If you are using smaller bookshelf speakers

that do not extend to the lower bass frequencies, set the

high-pass crossover control to a higher setting, between

125Hz – 180Hz. With this setting, your main speakers will

not have the burden of reproducing any low-frequency

sounds.

Final adjustment and blending of the low-pass and

high-pass controls may evolve over several listening

sessions. A good starting point would be to set both the low-

and high-pass controls to the same frequency and adjust

from that point.

Low-Pass Control

The Low-Pass control determines the highest frequency at

which the subwoofer reproduces sounds. If your main

speakers can comfortably reproduce some low-frequency

sounds, set this control to a lower frequency setting,

between 50Hz – 100Hz. This will concentrate the

subwoofer’s efforts on the ultradeep bass sounds required

by today’s films and music. If you are using smaller

bookshelf speakers that do not extend to the lower bass

frequencies, set the low-pass crossover control to a higher

setting, between 120Hz – 180Hz.

Phase

Phase Control

The Phase Control determines whether the subwoofer

speaker’s piston-like action moves in and out with the main

speakers, 0

°

, or opposite the main speakers, 180

°

. There is

no correct or incorrect setting. Proper phase adjustment

depends on several variables such as room size, subwoofer

placement and listener position. Adjust the phase switch to

maximize bass output at the listening position.

Remember, every system, room and listener is different.

There are no right or wrong settings; any setting you choose

will result in excellent performance. Should you decide to

fine-tune your system for optimum performance, be patient

and trust your ears. It will be worth the effort involved to fully

“tweak” your system.
