Wait, what? If I put in 91.5 dB sensitivity, 2W, 3m, in corner, I get 91 dB. Not 100 dB. Did I do something wrong?
Then
@voodooless posted a Hornresp showing like 105 dB for 1W-that is a hell of a lot more (closed perfect shoebox room?). I gotta wonder if there is really that much gain in a real room. And given that much room gain, do two subs really give another 6 dB? From some theoretical idea yes but I've never seen it tested that I recall.
Any possibility to measure the actual response of these subwoofers? My interest is very piqued. Ideally each separately and then together. I'd also be curious your comments why you chose that driver over a more "pro" driver (not disagreeing, mind you, just wondering what factors were considered)
