I don't necessarily disagree, I had a pair of 1971 H700 Heresy that I was thoroughly unimpressed with until I did the Super Heresy mods to them, making them roughly equivalent to the Heresy IV, giving them a significant amount of bass extension. Even then, I was somewhat dissatisfied, as they still needed subwoofers. That inspired me to play around with more horn speakers and I ultimately built a pair of Forte clones with a passive radiator, better tweeters and a bigger mid horn with a 2" driver. When I heard a 70's vintage pair LaScala for the first time, I was torn: there was no way I could live with speakers that big that still needed a subwoofer, the mid horn was shouty and the treble was sibilant, yet there remained something compelling about them, a clarity from the overall lack of distortion in the mid bass and midrange. I figured that from what I had learned from my previous experiments, I might be able to make them better, so I set about re-engineering them and built a new pair from scratch, selecting an 10x18" mid horn with a 2" driver, better tweeter horn and a woofer with much better specs than the OEM Klipsch driver. I enlarged the upper horn enclosure by 90%, sealed it, coupled it to the woofer doghouse enclosure and mounted a 15" passive radiator to the rear of the upper chamber. I then Tri-amped it with a DSP active crossover for parametric EQ and time alignment: the end result is a speaker that plays +/- 3db from 23Hz to 20Khz, with a linear phase response and time alignment, no subwoofers required and none of the shoutiness associated with vintage horn speakers, for less than the going rate of a pair of well-used vintage LaScala.
