Re: So many choices need a little help
100 wpc should be fine at your distance (12 feet) with the LX. By the linked calculator, you'd achieve peaks of around 100 dB, which is very loud.

I have a pair of LXs that I did put in my main system for a week or so. My amp is only 100 wpc, I sit about 9' from the speakers, and it was fine, even at louder levels. In an open floor plan and speakers were a few feet from back wall and about 2 feet from side wall. LXs now in my office (main speakers are ELX RAAL Towers).
