It really shouldn't matter what speakers you go with. When it comes to a good sealed subwoofer. You should be able to match it up with time and patience to any speaker.You have to decide which configuration you want to use. That's using the crossovers in the subwoofer as a filter for the mains. Or just running RCAs to the low level inputs, allowing the sub to supplement the LFE.
If you ever get the chance to hear these subs or any other decent sub run in stereo. You will wish you had two of them. It just isn't the same sound when they are run in stereo.The only way to understand it ,is to hear it for yourself. The key word is stereo. Running two subs in mono will not give you the same effect. Infact it may overpower the room with two subs run in mono depending on the room size.
