I agree with Hrcapers on the ARC amps on the panels. I recently found that replacing the non polarized electrolitic capacitors in the crossover found base of the planars with 250 volt polyprylene capacitors of the same value to make a huge improvement in clarity as well as control of the lower frequency of the planars, making them match the woofers better and giving less bass boom. Highly recomended!
Infinity Beta speakers
Does anyone have any tips for getting the best out of these speakers, room placement, or mods? I've been using them quite happily for a few years, but the bass always seems a little 'thick' and heavy.
