Well, lets put it this way,the SA-WX700 can outpound my JBL PB-12, and can play deeper or as deep. I opened up the cabinet today to see what it had, it could use a horizontal brace, and it didn't have any polyfill in it, but it sounds really clean stock, i wonder how much better it can sound with a teeny bit of mods. I can pretty much say that i'm 100% definate that it can go louder than the dayton,(never heard it though), just because of specs alone and amp power.
Heck, for $200, your getting a push-pull designed dual 10" sealed sub with 250 watts rms of digital power (sounds like a sony add lol), and the controls are really easy to get a hold of when the sub is in place, just lean over and its right there facing up. Oh by the way, i got mine for $149
