Dgage, I meant cheapest option with the Cap S1������, but found your info very useful for future research! You just threw in a whole new option into the ring... I'll be sound treating the ceiling (basement area) but am worried about shaking the house!
Haha, yeah! Provoked thoughts...its a good day.
If you're worried about shaking the house, might I recommend a smaller sub such as the JL Audio...LOL! I kid...sort of. But seriously, the S1 and even the DIY option I posted are powerful subs and could shake things in the house...and you'll love it. The key is to get the significant other involved early if that is in the picture. But with a concrete room, it is hard to say how the bass would travel in your house.
Well for Cap money, I could do a lot of dual setups (ie 2x VTF15H mk2). Maybe I'd add another Cap in the future, but it wouldn't be anytime soon. Thanks for the info though. I'll have to revisit this thread soon when funds have been allocated.
