hawkster Posted September 7, 2016 Share Posted September 7, 2016 About ten years ago, I bought and installed the K-Stack crossover for my Forte IIs, made by Chris Munson (akaPopbumber ). I was happy with the improvement in sound I got, and continue to do so. I do have a concern, though. I recently got an new Marantz 8802A, and I've been running the Audyssey MultEQ XT32 setup. Although my KLF-C7 crosses over at 110 kHz my Klipsch surround backs crossover at 120 kHz, and my Klipsch in-ceilings crossover at 60 kHz, Audyssey sets the Forte IIs to 200 kHz, even though they spec much lower. I got much the same result with my Onkyo 5508 in a different house. Since my RSW-12 sub maxes out at 120 kHz, it seems to me i'm getting a bass "hole" between 120 and 200. I would like to know if the K-Stack is creating this situation, but unfortunately Munson seems to have been a brief flash in the pan, so there's no help there. My options are 1} stick with the K-Stack and not worry about the numbers I'm getting from Audyssey, 2} reconnect the original crossovers, which are still in the speakers but are now 20 years old, 3} buy a pair of Bob Crites crossovers, appealing since his business is quite stable. Any votes on which way to go? Quote Link to comment Share on other sites More sharing options...
Frzninvt Posted September 7, 2016 Share Posted September 7, 2016 The K-stack is only a much better version of the original network on custom PCB's with better parts it is not a different design. The crossover points are the same. (Stick with it) If you are going to spend any money I would invest in the correct timbre matched speakers right now you have a mish-mash of different series speakers all with different timbre's. No wonder Audyssey if having trouble figuring it out. Get an Academy to replace the Legend series KLF-C7 and that should improve your pans across the front stage. In-ceilings are a big compromise not much you can do there. You don't mention what your rear's are but I would hope something from the same series like Quartet's or better yet another pair of Forte' II's. A compromise would be KG4's or KG2's. Lastly don't trust a computer alogrythm and an omnidirectional mic to make the final adjusrments for you. Run it then tune by ear with a db meter.
