Klipsch KLF-20 vs. RF-7 speakers

I suggest a mcintosh intergrated amp with tone controls, the best solid state and bass boost that works with these speakers hands down. Like the MC 6500 or 6900 even better with the 5 band eq to tame the mid's and up the bass slightly on these speakers, I had to do this with every klipsch I owned from the heritage which yes were slightly warmer all the way thru the current day Reference series. Tubes could help but normally will not have the punch for the bigger bass drivers in these designs, again in my experience, but I use them mostly for Rock and heavier faster stuff, but even the beatles benefit well from some re-balancing of these speakers with some slight tone control and solid power of solid state.

Crossovers are the key to moving these speakers to another level... A friend and myself decided one week to take an already great pair of mint RF3's using Dual 8's and a horn tweet/mid, we built a real serious pair of outboard crossovers eliminating the internal monster cable harness, and the real cheesy 3 inch square computer grade crossover... We used Goertz 12 gauge ribbon inductors, Mundorf silver caps, and I think it was either Vishay or Eagle Resistor .. We called klipsch and they gave us the official schematic cause the speaker was out of production, so we matched all values to a T'... Unbelievable advances in everything, like adding tubes, and a new Source like a quality DAC. It had about a 3db increase in sound pressure cause the volume was now way lower on the same amp, and the Bass was literally like adding a solid 12" sub somewhere in the room, no joke. Beyond that the Control physically of the drivers was like a VISE, the 8's now bareley moved and sounded so much cleaner. It was worth the couple hundred no doubt, Plus in some of the klipsch 2 way or I guess might be 2.5 ways there are very few parts, it seems they are 1st order's, cause only had 6 parts total on each board and we built them still with the Biwire posts.. I also did this to a pair of Cornwalls, it helped but was not as dramatic cause due to the 3 way it cost a lot more to use the same caliber of components that we did with the reference series, the biggest difference and Mistake in this case we believe building the cornwalls was that we ended up with Simple Solen 14 gauge inductors and they were built physically with much smaller parts to get away from just building seprate cabinets for outboards.. That was a pretty big difference though.
