Sid K Posted January 27, 2017 Share Posted January 27, 2017 Hi Everyone. Its me the guy always asking questions and looking for the answers from youse This question/topic came up in another of my threads on an unrelated subject. I had pointed out that I didn't like the harsh sound from the midrange. I was exploring changing the horn...thats another topic...no need to now (thats my opinion) Deang had pointed out the possibility of it being the K55 driver (mine was probably a late 70's version) I took his advice and I replaced it with the A55-G! He was absolutely right. I have only listened to it for about 5hrs so far. I don't know where to start with the improvements...its like listening to all of my music for the first time. The seperation, detail, natural effortless sound too name a few. From the reviews I have read about the A55-G I absolutely agree. Amazing. I have also changed out the K77 (also probably late 70's version) with a B&C driver and eliptrac horn. With the same results. If I would have known this I would have done this many years ago. Deang Thank You Very Much! Quote Link to comment Share on other sites More sharing options...
Sid K Posted January 27, 2017 Author Share Posted January 27, 2017 Oh..by the way..no more harsh sound. Even when I turn it up..its still a nice, easy, smooth sound. I listen to hard rock mostly and I have noticed the voices, snare drum, guitars, etc. are more apparent and distinct now. The bass is more apparent now as well. Not distorted. It doesn't hurt my ears anymore except when I listen to it way to loud for long periods Self inflicted. Quote Link to comment Share on other sites More sharing options...
Honeybadger Posted January 28, 2017 Share Posted January 28, 2017 Excellent, I was hoping to hear more about this driver. HB Quote Link to comment Share on other sites More sharing options...
Deang Posted January 28, 2017 Share Posted January 28, 2017 It's a well know fact that some of the single phase plug K-55-V's had a terrible "bounce back" at 9kHz. The ALK Universal provides adequate rejection, but the Type AA with Max Potter's "P-trap" does even better! However: the best answer is to invest in a better driver. I'm glad you're enjoying the Allen driver, which is a worthwhile investment. 1 Quote Link to comment Share on other sites More sharing options...
Wirrunna Posted January 28, 2017 Share Posted January 28, 2017 Here is a thread from way back that I found on the same harshness problem. 1 Quote Link to comment Share on other sites More sharing options...
jjptkd Posted January 28, 2017 Share Posted January 28, 2017 Yes, I suspect eventually the majority of Heritage owner's will have switched over to this new driver as it seems superior to the older Klipsch models, I just wonder when, if ever Klipsch will start offering them in their new speakers?

Wirrunna Posted January 28, 2017 Share Posted January 28, 2017 Sid, I followed mark1101's advice and built an extreme slope crossover, the ES400 for the woofer / mid and an ES4500 for the mid / high as I have a Bob Crites CT120 tweeters. My A-55Gs are in the post and should be here next week. The ES networks certainly cleaned up the harshness and widened the sound stage. I expect that the A-55Gs will make the sound cleaner.
