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


Modifications mean “tuning” the component to your taste and to work better with your other components.  That means that any particular change may not be an improvement.  Make sure that any change can be reversed.  Damping horns is something easily done and reversed.  Likewise, putting thin felt strips in the horn opening can be tried and reversed.  If you are going with crossover modifications, make sure that the modifier gives you back the old parts so you or someone else can undo the change.

The biggest change, most probably for the better, would be to find a suitable tube amplifier.  Take your time hearing alternatives. I know it is a matter of taste and system synergy, but, I find the MC 275 mentioned as a suggestion to be less than mediocre, particularly given the price.  There are many low power tube amps that would work well with these speakers.

@atlvalet id be less skeptical if one of these charlatans had the conviction to post before and after videos so we could A/B the difference. And not a bunch of useless graphs like Danny. Actually A/B the before and after with various songs in a controlled test. I also have no idea what obvious horn resonance you are referring to. If it’s so obvious please try and isolate the sound and share with the group. Im sure the guys at Klipsch would also appreciate this discovery.

As for things like “cheap Chinese” caps and crossover components, it’s the same rationale as generic cable vs pricey esoteric stuff, if the cheaper components do the job there isn’t much need to pay up, aside from placating a small, fickle group of audiophiles.
Sorry if I come across harsh but I’m just so sick of people pushing snake oil without proper blind testing. So many of the ideas revolve around cognitive dissonance and reviewer bias and lack actual merit. Klipsch has literally been making Cornwalls since 1959 and horn speakers since the 40’s, and not a single model uses sound deadening material on the horns. Yet Im supposed to take your word for it, because some other guy said it was a good idea? Hard pass, I’d rather listen to them as they were engineered to sound.

Klipsch used cheap parts in the xover and the binding posts are a joke. Face it, most of their client base is not into truly high-end audio, so why spend on ultra-premium parts? It would make no business sense. Subbing in great parts makes these good speakers great. This I know for a fact, having done it and heard the difference, which was not subtle.

@wrm57 so prove it.  If it’s not subtle then it should be easy to demonstrate in a video comparison.  Please note, I’m not expecting you to actually tear apart one of your speakers just to prove a point, but I think your claim is absolutely worthless without some type of demonstration. There are thousands of audio videos on YouTube, some of them with terrific A/B comparisons. But it’s almost always different speakers or different amps which show audible differences. I’ve never seen any audio tweak or cable videos with actual sound demos. I wonder why 🤔

It is true that low cost parts do not necessarily mean bad sound or a substantial compromise in sound quality.  At its price point, the Cornwall cannot be built without some cost cutting and savvy design means making the right choices on where to use “cheap” parts.  But, to suggest that those who substitute parts or modify the design to improve its performance or better suit their preference are just “fickle” and must meet some kind of blind testing criteria to justify their choice is unreasonable.  First, it is a personal choice and does not have to meet a long term market-supported approval measure.  Second, is there any evidence that Klipsch applied blind testing for every one of their design choices?  I bet they do what most of us do; they listen to the results.  I am sure Klipsch designers hear many improvements that they chose not to adopt because of cost, manufacturing difficulty, or some other practical consideration.  Those consideration may not be in play to stop an individual from making a modification.
