I recall a thread a few weeks ago praising the X-LS encores. In brief, I can attest to the FACT that these
are great speakers and Ron's build both looks excellent and appears to have high quality parts and tweaks.
FWIW, if I was seeking a pair of moderately priced bookshelf sized speakers, especially for $500 or less [probably even $1000],
the X-LS would be my suggestion based on having actually heard them. Solo, they are great with a wonderful clean and clear high end.
Paired with dual subs, I was somewhat knocked out by what I was hearing. I have zero vested interest in stating all this, just passing
on what few pearls of wisdom acquired on the journey. Sound great at low volumes and can play quite loud, too.
