The "most foolish" loudspeaker tweak/upgrade ... is


I suggest Von Schweikert Audio's "ULTRA Internal Wire Upgrade" at a 'mere' $39,700..

Well...um...getting back to the subject matter of the thread: this one isn’t the most foolish because it’s free but imo it still qualifies as foolhardy.

You know the one where you place several coins of the top front edge of the speaker cabinets? Even Sam Tellig fell for this one; perhaps that in itself tells you all you need to know about high-end audio reviewers?

Now I’m all in when it comes to the practice of placing certain objects/masses on speaker enclosures in order to reduce cabinet resonances. But coins? Coins weighing several grams at the most are going to affect/reduce resonances on speakers weighing 1000X more than the coins?

Nyet. It’s expectation/confirmation bias in its’ most benign form and to me it’s sheer folly. But like I said before...it’s free so knock yerself out.
Gee, thanks for the warning. But if it's coins it not really free, is it?

Well....if the coins just sit on the tops of your speakers then you’ve never spent them, huh? Saved maybe but not spent.

Didn’t think that one clear through there didja?

And what a coinkydink that a member who's profiteered more from expectation bias than any other A'gon member would chime in with a bit of sarcasm....

The coin trick does in fact work but they must be 1937 Buffalo Nickels otherwise it detracts from the soundstage.
