whooo, this thread got some activity since I was here last

Thanks for everybody's input.
I got an answer from Outlaw about crossborder customers and it was what I suspected. Thanks to eljaycanuck and warpdrive for reminding me of this.
Looks like it's going to be SVS PB12-NSD...x 2
Thanks for your post Archea and Mupi, what you said makes sense. I can't afford to chase mid teen Hz, but I want to be able to recreate at least 20Hz. My current subs, as good as I think they are for the money, can't. They will do mid 20s but you can tell that they are at their limit. Like I said in a previous post, I also want more headroom. I think that the PB12-NSD will give me what I'm looking for.
DIY, is not for me. I usually hire a contractor to hang pictures

When I get it, I hope I can make it play nice with my PA-120s until I get the other one.
