Amp matching for Klipsch Forte III

Klipsch Forte IIIs were my first high-end speaker and I played with low-wattage SET amps mostly.  They were so much fun and so revealing!  It seemed I could drive the Forte IIIs with the wattage generated by a lit match!  I noticed pretty quickly, though, that there was a harshness to them with poorer or more processed recordings (although with some many variables in a system, who really knows the cause).  Bob Crites, by email, suggested I try a fabric-based midrange dome (rather than titanium).  I never did that, though (scared of ruining the speaker).  I wish I had read more about the damping treatments that have been recommended here.  

I don't use the Forte IIIs as my main speakers anymore because I discovered the joys of single-driver (plus subwoofer) speakers for imaging precision, something the Forte IIIs were not as good at (lack of time coherence??).  My Omega Alnico driver has nicer midrange than the Forte IIIs as well, although dynamics are not comparable.

BTW, I also use Pass XA30.8 power amp w/ tube preamp.  Great combo!

This may be of interest.......

Try getting them spread as far apart as practical. Then fire each speaker at your opposite shoulder. This should have the axis crossing very slightly in front of your listening position. This worked for me when I had the Forte IIIs and works very well now with the Cornwall IV.

have run with rogue 180/belles 350/prima luna all with good results..look at gr research the make an upgrade kit that brings these to a new level and may adress some of the issues

i think it is common knowledge that super efficient horn loaded speakers mate well with very pure sounding low powered amps, generally tube but also solid state ones

i went that route some time ago, and still have some lovely lovely SE tube amps by Cary and Gordon Rankin/Wavelength, but I gave up on such speakers due to their colorations and 'shoutiness'... of course, this is a tradeoff to get the efficiency and the 'effortless' way these speakers portray dynamics in the music... for me, the trade wasn't worth it, i went back to more 'normal' speakers that delivered a more controlled, neutral and natural tone
