Hey guys,
If you use Paypal then the 3% Paypal fees are paid by the receiver (me) and not you (the receiver). The same goes for credit cards. I can accept any major credit card too, BTW.
The servo sub is the highest quality low frequency reproduction subs on the market. And they work just fine for home theater applications as well. Nothing about the home theater application changes anything other than the fact that some people want even higher SPL levels for some movies.
We don't offer a 15" woofer. It just didn't make any sense to do so. The 12" woofer already plays flat to 20Hz and is -3db down in the teens. So going to a larger and heavier moving mass only increases the time to return to rest and sacrifices quality. I advise that if you need more output than a single 12" servo sub can provide then use two of them. That gives you more SPL without sacrificing quality.
I use a single 12" servo sub in my room that is 17' by 23' and has 9' ceilings. It can easily balance to the output levels of any speakers I use. But I am not looking to over blow the bass or bring the house down either.
If you are looking for really loud SPL levels then you might want to use 2 of them.
Ported boxes are used to extend low frequency extension beyond that of a sealed box. But with a servo sub a ported box is not necessary. The servo control will force the driver to maintain a linear response down to whatever the extension filter is set for. So going to a ported box just adversely effects the group delay and nothing is really gained.
The woofer is 20 pounds and the amp is 18 pounds.
