IMO, EQing the subs independently only makes sense if they are operating in stereo mode (i.e. they are each reproducing different program material). For HT applications where both subs receive the same signal (either from the LFE track or redirected bass from the satellites), the way Sub EQ HT operates seems ideal to me. I can't imagine what advantage independent sub EQ would provide in the HT setting.

Each sub can produce it's own unique set of interactions with the room. Therefore IMO, the best solution is to EQ them individually 1st, then collectively.

If one sub has a "problem" freq, and the other doesn't, seems to me that dealing with that freq only from the sub that produces would be the best approach. The incoming signal, stereo or mono doesn't matter. It's the interaction with the room that matters.

I guess we'll have to agree to disagree, then.

When two subs are reproducing the same signal, the only thing that matters is how their combined output interacts with the room. Equalizing them separately in such a scenario only complicates matters and offers no improvement to the final outcome. That's precisely why Sub EQ HT operates the way it does.

I think Sub EQ HT works the way that it does because it doesn't have the processing power to do it individually.

And I think individually EQ'ing multiple subs first, then the combination can give you better results than just doing the combination alone. Especially over a listening area, not just for one spot.

The SVS box can do this, and JBL's BassQ too.

Even if the subs are acting in stereo, the important part would seem to be, how they interact with one another. Typical speakers operating above the sub range don't produce the bass nodes which subs do and don't interact with one another as much. It then seems that the only way to integrate two or more subs is to tame the overall effect vice trying to tame the individual effect since any real world application will have to deal with the bass nodes from both speakers. Also stereo subs may produce different signals but since they are LFE they are essentially directionless so the "stereo" effect is pretty much negated.

Definitely not. Modern receivers like last year's Denon 4311 can EQ 11.1 channels already, so another fractional channel (subwoofer output below 250Hz) won't strain the processing chip. You'd never be able to support your belief with measurements, because they would demonstrate that the opposite is true. EQing the acoustic interaction of multiple subs can produce better response AND greater consistency over a wider listening area than EQing each sub independently.

E. F. Hutton has just spoken... for those old enough to understand the reference.

I was hoping you would find this thread at some point, Sanjay.

Yes,unfortunately it is well with in my frame of reference age wise and well said. I enjoy all the knowledge I have gained since joining this forum.

I remember those commercials. Now, do you remember his daughter (actress Dina Merrill)?

The name certainly rang a bell, but it took a trip to Wikipedia to refresh my memory. I have seen several of her films and TV shows but can't honestly say I remember her in any of those roles. "The Player" would be well worth watching again to see her in the twilight of her career... terrific movie, btw.
