I love my Klipsch Heresy IIIs used with a couple of REL subs, and the new Heresy IVs might be even better although I haven't heard them. Clean and clear with the punch and dynamics that efficient speakers seem best able to deliver...another advantage of efficiency is the ability to use pretty much any amp, regardless of wattage.
purchasing US made speakers
I currently have psb imagine t2 speakers. I am interested in replacing them with US manufactured speakers 10-12 k being the maximum price....perhaps aerial acoustics, vandersteen,,,,,any thoughts? My hearing at age 70 diminishes at 8,000 hz so a good midrange is probably good.
