 Both my front and center speakers have accurate tight base response. The center speaker has frequency response of +-2 dB from 53 Hz to 18khz. Why would I not want the full voice from a TV announcer to come entirely from the center speaker in full accurate fidelity, rathar than split between the center and the subwoofer. This is what the speaker was designed to do.
Likewise the front speakers have been my only speakers for the last 30 years and are capable of very accurate music reproduction. I always liked their acccurate base response. |
I understand your concerns, You have to remember that the crossover setting is not a shut off of the frequencies below that point but rather a roll off of them. So there will still be plenty of frequencies down to at least 60hz before its dies off. The human voice does not go below 100hz anyhow. So for listening to music in two channel direct mode the crossover is disabled anyhow as in most cases the sub is off for that setting.

Another factor is that if I turn up the subwoofer output to accentuate the LFE effects in a movie, it might unbalance the sound coming from the other speakers.

This should not be an issue as the PB13 is way more capable of doing the job than any full frequency speaker. and by having the bass going to both could actualy caus you more grief.

For accurate response from the subwoofer, do I use the internal tones, or is there a better method. The subwoofer is currently +8 dB more than the other speakers. If I set the speakers to 80 Hz, I will need to have the proper level between the subwoofer and the other speakers.

Ideally a test tone sweep is best as you can hear the sweep pass through the 80hz area and you will be able to tell if you have to much or to little. DVE has this sweep on the DVD I dont remember if Avia has it.
REW is ideal for this as it not only has this feature but shows you on a graph what you have.
