So Boom what db levels are you talking about? Are you like at 70db and garbulky at 90db? Mark Hi mfeust - Yes, I think you're pretty close. I'm most of the time between 65 & 75dB (and to my ears, 75 is LOUD). garbulky probably listens (in his own home) at between 75 & 85dB (but this is a guess on my part). HOWEVER, when garbulky comes to my home to hear new gear, we've routinely cranked between 85 & 95dB for brief periods. I can tell when garbulky thinks the system is sounding good - garbulky's body language gives away his opinion. He'll begin "couch dancing" and playing "air instruments." Sometimes he'll hum along or sing along with the music, and his feet tap along with the rhythm. I don't know what I do - I'm so busy enjoying vicariously my buddy's appreciation of the music that I just smile. Of course, when things AREN'T dialed in, garbulky will fidget from side to side on the couch, trying to find the (currently non-existent) sweet spot. But he's really good at diagnosing what he thinks is the problem, and he's now familiar enough with my room and my gear that the issue can often be set right promptly. Being about 30 years my junior, his ears are a lot better than mine, and I trust his impressions. Boom Hehe...my levels are louder than yours but not by much! . When I measured I listen at about 68db with peaks at 75db. Now when we test your subwoofers we might be listening in the mid 70's average and peaks in the low 80db. My requirement is that acoustic instruments are a the same volume as I would hear them in real life unmicced. And yes, I was definitely enjoying myself. I think I do every time I visit!

Boom also mentioned elevating Subs- total agreement. People can argue until the cows come home that down-firing subs into the carpet are no different than front-loaded, even better. BS. My Sub has both and can hear more when it's elevated.

Boom, How do these compare to the S1512DFs that you had at one time? I have those now and they are okay in my room, but at the close out price on the S15s I can be tempted to switch. Hi davidl81 - If I already had the PowerSound Audio S1512DF subwoofers, I don't think that the switch to the Emotiva Airmotiv S-15s would be justified. The latter actually sounded pretty mundane until I got them positioned properly and away from room boundaries. But what works in my room is virtually certain NOT to work in yours because of different room dimensions. But I would say, in general, that just plopping down ANY sub in the most convenient room-location is highly unlikely to produce the best bass. My guess would be that the inherent subwoofer quality and capability makes for 40% of the potential performance, and that placement makes 55%. The remaining 5% has to do with measurement and application of electronic room correction (anything from analog equalization to full DIRAC). Now even the best placement and equalization can't make a Ferrari out of a Fiat, but provided your subwoofer is at least "good" (and your S1512DFs are VERY good) then you've got the bones of world-class bass! Boomzilla I drank too many Sazerac’s in NOLA and ordered the S15s. For $719 a pop I figured it would be fun to try out the pair.

View AttachmentI do find that my down firing PSA subs tend to radiate more sound downstairs (my theater room is upstairs) then my older SVS subs did. In my theater they sound the same, but a lot more bass in the other rooms. I did just order a pair of the S15s that were factory renewed so I’ll see if they sound any different.

One peculiarity of the Emotiva Airmotiv S-15s - They "thump" intermittently for about 30 minutes after turn on (but no more than once or twice each). After that, they're dead quiet. Not an artifact of upstream equipment - the subs thump with or without the other gear turned on. And both subs do it at random.

It's not crazy loud or anything, but slightly annoying. As a side note to more I dial in these S15's the more I like them. I think these were an amazing value at $719 per sub.

I think that maybe Emotiva cheaped-out on the power supply caps in the S15 plate amps. The good news is that they DO have a 5-year warranty, and Emotiva is good about fixing whatever breaks. If the thumping remains as is (no more than one or two relatively soft thumps in the first 30 minutes of operation) I can live with it. If the thumps become louder or more frequent...
