purchasing US made speakers

Do you have sub-woofer/s with your setup?

I don't feel that I really need them for music, though they might add a bit. But my system is multi purposed for home theater as well, so could use them there.

I actually have a JBL sub-woofer which was included in the setup when they calibrated with the wavelet. It puts out next to nothing. 

I have a pair of Legacy XTREME XD subwoofers that I usually use with the Whispers when I want FULL range, FULL output.  Amazing difference su h subs make, even with Whispers.  When comparing speakers for review,  of course it must be apple's to apple's either way. The XDs were also reviewed. 

A pair of the Xtreme XD is what I was thinking, or possibly a single Goliate XD.

What positioning did you end up with in your setup?

Imo the pair is superior for stereo. Flanking,  see system images for idea.

Man up, get a pair of Goliath subs!
