Aerial's bass is tighter, and I think it is a lot more tune-able, so its less room dependant. However, if you already have Revel speakers you couldn't do much better than matching it to a B15.
Aerial Sw 12 vs Revel B 15 Subs ?
I am looking for a sub that does music best and ht second, I have heard the aerial and was very impressed musicly, but it did seem to bottom out (popping) during intense movie soundtracks, I have not been able to audition the revel, can any give me a comparison, thanks all
