@rajugsw please tell me you have some before and after audio you can share.
klipsch cornwall iv upgraded crossovers
I own a pair of cornwalls, amazing speakers they are paired with MC452 power and a MC 70 tube pre.I play cds only on a yamaha C2100. My question is I hear people talking about upgrades to the crossovers on the corns and softening the horns with sound tape . Do any of those changes work,one or the other and do they make it worthwhile. Would like input from anyone who has tried the upgrades and who they used

Actually never mind, I just found this guys video comparison Dynamat mod on Klipsch. Personally I think it sounded better before, less muffled. Yes, different speaker but I think I’ve gotten my answer on that particular mod, the difference was actually more pronounced than I was expecting. |
https://forum.audiogon.com/posts/2350554 I’m not sure why one would consider posting frequency response curves as the work of a charlatan...it’s literally measured data. I mean, I’m not making a purchasing decision based solely off data, but hey...that’s just me. |
As I said before, these modifications tune the speaker to fit the owner’s particular taste and system, and as such, the changes can be unfavorable. A local dealer in my area makes custom speaker systems (mostly horn-based) and tuning involves trying external damping of the horn, applying thin felt strips to the inside of the horn, changing the type and amount of damping to the sides of the cabinet, changing crossover parts based on a prospective buyer’s preference, etc. I get to hear these changes, and any one of them can result in dramatic changes. The issue I have with the kind of modifications mentioned in the video is that a lot of people assume that certain types of changes are always better—more damping is better, more expensive caps are better than cheap ones, etc. Additional cabinet damping might make the bass tighter, which one person may like, but someone else might find the sound to be too dry and lifeless. The type and brand of caps that sound good is likewise subjective. The custom builder I mentioned above thoroughly hates Mundorf caps in any of his speaker or electronic builds. If you ever heard the effect of even a tiny change in the level of the midrange and tweeter, you will appreciate the value of L-pad attenuators controlling such drivers. I don’t understand how manufacturers expect their designs to be optimized to the particular buyer’s taste and room acoustics such that such basic adjustment is not necessary. The removal of such controls has to be among the worse modern design trends; reversing this by adding back controls would probably be the best modification one can try. |
@larryi well said. Changes are not guaranteed to be improvements and there certainly seems to be a tendency towards more is better. That’s kind of where I was going with bringing cognitive dissonance into the conversation, it provides a behavioral explanation as to why a rational person might go down that path and then vehemently justify their choices. Personally I tend to “trust the chef” but I get why people like to tinker and modify, it’s a fun part of the hobby. Every room is different so it’s not like you can expect everything to be optimized straight from the factory. My mods tend to come through positioning and amplification. I don’t even like to use tone controls, but I see value in them along w advanced room correcting software. Mostly though I get annoyed when industry people overstate the value of these mods and the assumption that they will result in a noticeable improvement. |
