YPAO Multi Point vs Single Measurement

[Craig Payne]

Apologies if this has already been discussed on the forums.

I have tried running YPAO multi point calibration on my Yamaha RX-V3081 and have found that my dual subwoofers levels are really low in volume. It is better to do multi point or single point calibration with dual subs?

I am running dual Paradigm PDR-100's.

I'd say in general any of these room eq programs do better with more information about your listening area, so multi is better. The resultant sub level may not be your preference (it may be more a flat response), no problem in ticking it up a few dB for preference, many do. Some of the YPAO versions don't do much for the lower sub frequencies, either.

How did you place your subs? That can influence their response more so than the room eq....

Thanks for the advice. The subs are placed diagonally front right, back left conrners

Usually a decent way to go, but did you confirm those are the best places in your room with measurements or a bass crawl or ? Modes can be tricksy.

I did measure both subs independently with an SPL meter to 73db prior to using YPAO multi. Is this something I should do again? I do not have a flexibility with sub placement due to my room layout. So diagonal was the only real placement option due to limited space at the front listening position.

Measure it with an spl meter, if it's relatively close to 75 dB I'd say it's correct. Have you set the.phase in the subs? Does the receiver only allow for adjustment of a single sub output or dual? If it's single, I'd set the distance for the sub closest to the mains and invert the phase on the rear sub and see how it sounds. Also keep in mind a second sub should add a 3dB gain at a distance and a 6dB gain within 1/4 wavelength, so 73dB for a single sub measurement would be more like 76-79dB.

That's called level matching, and would depend how you did it with an spl meter. If you have no other placement options then its simply a moot point....and let your avr do what it can. I would try boosting the sub level in the avr a bit....
