Axiom Home Page Forums General Discussion Technical Questions Bass Management Confusion...

If your using LFE+Main then the sub is receiving those signals. The point of setting the receiver to small on all speakers is to let it be less taxed, and let the sub pickup the LFE it is designed to do. The sub has its own amp.

Mitch, no you're not really on the right track; as was said, the idea is more nearly the opposite. The sub is designed to handle the lowest bass frequencies better than the mains and to take some of the load off of them. You need to let it do that by setting all of your speakers "small" and assigning the sub alone to handle those frequencies.

John, not sure this is a problem, but his AVR is locked at 100hz. My guess is thats close enough to 80hz he should not have a problem?

Sure, if it's 100Hz(I haven't read the manual), then that's what has to be used. The localization probably wouldn't be a major problem.

Would it be better to allow my subwoofer (Velodyne CHT-12) to use its internal crossover, which I would then set at 80hZ, instead of using my receiver's built in crossover?

No, Mitch, the sub's internal crossover just rolls off the sub above the selected frequency; it has no affect on the main speakers, which would continue to play full-range if they weren't set "small" in the receiver(unless the CHT-12 has a separate high-pass filter on an output to the mains).

hi Mitch
I have the same sub, and as John mentioned, it does have a high-pass filter. That would allow you to send the entire audio signal to the sub which would then seperate anything above the selected crossover point on the sub and send it to the mains. However, for ease of operation/cabling you are probably better to rely on your receiver to handle the crossover functions. Continue to use a coax cable to send the audio signal to the sub and crank the crossover knob on the sub to the max.

Thanks all for replying...forgive...I'm confused...if I set my subs crossover to max..
What setting should I be using on the subwoofer.
A) Internal X-over or
B) Direct
????
Thanks Again
Mitch

Don't you have a manual? I just did a search on Google and found this...

"Subwoofer Direct input This input bypasses the CHT Subs' internal crossover to provide direct connection to a preamp-level subwoofer or LFE output. This exclusive feature assures the highest levels of performance and compatibility with all digital surround processors, now and in the future."

Sorry about that SirQuack...
when setting to direct, should I set it to 150Hz, or 85Hz?
