After reading all of these excellent responses, I'd say that it comes down to this: I believe I understand the various operative aspects of getting smooth bass in a smallish room, but I remain a bit daunted by the whole measurement process that seems key to achieving said end. Everyone recommends REW, but what are the steps, salient points, and potential sticking points involved in a measurement scenario involving 3/4 subs, plus mains, that need to be be observed? Surely the collective wisdom and experience of a forum like this has certain guidelines that could clarify this process and make it make it much more approachable that it seems currently. For example: I hear little discussion of delay. AVR software seems to be set up to compensate for the different distance between 1 sub and the mains and the LP, but how can this be achieved with a multi-sub array in which the distances all vary with respect to the mains and the listener? Seems to lil ol me that this should be critical. Is it not?
Nico,Digital delay is just another method or another way of saying phase alignment so yes it does matter. It’s assumed you are doing that and using those methods to reach your goal of flat bass response. Have you read Paul Spencer’s guide on Hifizine.com for proper bass integration of multiple subs? I highly recommend it, Parts 1-3. Read and reread it until you understand it. It will save you loads of headache. http://www.hifizine.com/2011/06/bass-integration-guide-part-1/http://www.hifizine.com/2011/09/bass-integration-guide-part-2/http://www.hifizine.com/2012/06/bass-integration-guide-part-3/Best,Anand.

Measurements don't guarantee good sound. Ultimately, you gotta rely on your ears. There's room limitations, spousal acceptance, and sheer practicality to consider. For instance, I can only add a 4th sub in one location in my room, and it's probably not optimal. And my third sub isn't optimally placed, but I have no choice. Measurements can't fix poor placement.
Hey guys, how about a setup using 3 or 4 of these cheap (but well-reviewed) monoprice 9723 subs?:https://www.monoprice.com/product?p_id=9723&AID=11051853&PID=5431261&ref=cj&utm_source=cj&utm_medium=11051853&utm_term=Skimlinks-3449840http://www.avsforum.com/the-best-budget-subwoofer/Only $100+ shipping each.-Jim
Unfortunately response down to ~50 Hz is NOT a subwoofer. You'd be missing a whole octave. Heck lots of monitors go lower.
The CEA-2010 measurement is not a traditional frequency response curve. From a very casual skim of the explanation it appears to be the maximum output at various 'subwoofer' frequencies before specified distortion levels are observed.If I am interpreting things correctly, if you listen at 100 dB the Monoprice subwoofer will go down to between 20 and 25 Hz. http://www.brentbutterworth.com/cea-2010-measurement-manual.html
Yeah, very interesting sub and review. But it must be noted that it's not REALLY $100. Probably more like $125 - $150, depending on shipping. But if it's that good, that seems like a good candidate for a budget swarm.
