BasX Subwoofers
If your AVR or pre/pro has a full range subwoofer output (but not bass management), then
there’s one additional step.
- AFTER you’ve set the Phase Control for the most bass, go back and adjust the Volume
and Crossover Controls for the best sound. The Crossover Control controls the overlap
between your subwoofer and your main speakers; you want to set it so that your sub blends
smoothly with your main speakers, without a bump or dip where they overlap, and without
a sharp transition from one to the other. The Volume Control is used to set the relative level
between your sub and main speakers. A good rule of thumb is that the bass should sound
solid, but you should not hear the sub as a distinct separate sound source; try turning the
Volume Control up until you barely notice the sub, then back down a tiny bit.
Note: The way your main speakers and sub blend together will sound slightly different at
different locations in the room. These adjustments should be made by listening at your
normal listening location... If your equipment is located across the room, walk back to
your favorite chair and listen to the results from there each time you make an adjustment.
Note: After you’ve configured everything on your pre/pro, or used your automatic room
correction to do so, you should AVOID changing the Crossover and Phase Control settings
on your BasX sub as this will change the way it sounds. However, you may use the Volume
Control to increase or reduce the amount of bass to suit your taste.
Configuring your BasX Sub Manually
If you’re connecting your BasX sub to a stereo system that doesn’t have a subwoofer output,
you’ll be using the controls on the BasX sub to make it fit perfectly with your main speakers.
- First you’ll need to take a set of main outputs and connect them to BOTH inputs on your
BasX subwoofer. It doesn’t matter which channel you connect to the red input and which
to the white input since they’re summed together. If you only have one set of main outputs,
you can use a pair of splitter cables to send a copy of those signals to your BasX sub.
- Start with the Volume Control all the way down; with the Phase Control set to 0 degrees,
and with the Crossover Control set to the far right - to LFE.
- Now, play some music with plenty of bass, and that you are familiar with.
- Turn the Volume Control up until the amount of bass sounds more or less correct.
- Use the Phase Control to adjust for the MOST bass in the frequency range where your sub
and main speakers overlap.
- Fine tune the setting on the Volume Control so that the amount of low bass and middle
frequencies seem about right in proportion to each other. At this point you’ll probably have
a bump in the frequency response where the sub and your main speakers overlap.
- Finally, turn the Crossover Control to the left to reduce the overlap between your sub and
main speakers until everything sounds best. (You’re lowering the crossover frequency to
eliminate the overlap between the sub and your main speakers.)
- If necessary, you can adjust the Volume Control one final time to get things just right.
