My current speakers are a pair of the Frugal horn Sachiko Double Horns. They call them back loaded horns, but really they are a transmission line. I got the cabinets from a person off of Audiogon in California. First I installed a pair of the Fostex 206 drivers in them, but these drivers are just too coarse for my liking. Eventually I located a pair of first generation 208 Sigma drivers, and got them installed. Significant improvement, far more refined and better tonal balance.
I wired the cabinets with Cardas SE 15 series speaker wire, and Cardas pure copper binding wire. I lined the driver chamber with Sonic barrier from Parts Express, and a small amount of Dacron at the throat of the lower and upper horn throat.
Speaker is 97 or 98dB efficient, and is able to be run off a SET with Type 45 tube. 3dB down point is 50 hertz, and i run them full range with an Infinity Cascade 15 subwoofer for the bottom end.
I like the speaker system, but its really not a true horn. I have a couple of friends with modified K Horns, some custom built 3 way horns with J bass horns, a mid horn that looks like it belongs on a Victrola, and a horn super tweeter, and one that has some custom Altec/GPA 604 speakers. Of the bunch the custom 3 ways are bar far the best, but its taken years to get them right, and require multiple amps, and a computer system for x over, driver time alignment, and digital room correction.
i do not have that kind of money, or wood working skills. So the Sachiko are going to have to be good enough for me for the time being.
