Free speaker tweak that's a must do

Yeah, well, Erickminer, you have a good fix on why the ProAcs drove me nuts. "Careful" snugging only meant that the screws would work themselves loose almost immediately, but I was aware that using too much torque would be worse.

Erikminer,Its common knowledge across any industry using fasteners of most any type that over torquing will cause faster to loosen. If there loose already fine but just to tighten because its what I do shows a misunderstanding of how bolts screws etc work. And that's not about being a audiophile. Its about basic understanding of how things work.

That is why i like MAGICO no screws to tighten

No over torquing will not cause a bolt/fastener to just loosen but it will add addition stress to the bolt which may cause it to fail over time. And really it depends on what we are torquing. As an example the wheels on your car have a specific torque spec.. probably 80 ft lbs or so. I GUARANTEE that unless you torqued them yourself they are not at spec, but over torqued. In fact most all wheels are put on over tight. If we use your theory then there'd be a lot of wheels falling off cars. For the most part a little over torquing isn't a real issue, huge gorilla over tightening will just cause either the bolt/ screw to strip out, or in an extreme case for the fastener to fail.

Good tweak....also...remove speaker grilles for critical listening...lastly...bought some large metal cone/spikes at hardware store...placed on top speakers ala totem...reduces reasonces...bass tighter....just my .02
