An "insane" idea - maybe
Well, I thought I'd heard about every nutzy idea for "sound improvement" in the world - until last night.
A friend called to say that he and another friend had "discovered" how to make Polk speakers sound smoother on the high end - and would I like to come over for a demonstration? As he was serving good Scotch, I decided what the heck.
His friend had recently purchased a pair of RTi6s for surrounds. And he has a relatively new pair of the floor-standing RTi8s. OK so far.
Well, his friend had read somewhere (Science Fiction magazine?) that if you take a very soft cloth and "massage" the soft-dome tweeters it would "break them in" and make for smoother highs. What? Whoa, here, fella!
Anyway, he'd gone ahed and "massaged" his tweeters for about two minutes each - and swore his speakers sounded better. I assume this was AFTER drinks? Anyway, I needed a free drink, so what the heck.
Went over to the house, where they had all four speakers lined up against the wall - one pair to the "A" outputs of the amp - the other pair to the "B" outputs. So far, so good.
First, I took a look at the "massaged" RTi8s - didn't look any different, but the chap explained that Polk tweeters are "crackly" when first touched, but, as he put it "age out" with a little direct attention. Yeah, I thought, there goes the old Polk warranty! A little slip and WHAM-OH!
To the test. We put on Renee Fleming's new "Bel Canto" CD - and listened. I'll have to admit the "massaged" speakers did sound good - but then we flip-flopped back and forth between the two speaker sets, using A & B outputs alternately. Hmmm. . . maybe I was just hearing the difference between the RTi8 and RTi6 - but the very highs in the 8s DID sound smoother.
After about 15 minutes of that (hated to stop the music!) plus a nice glass of 12-year old Scotch (always makes the music smoother!) it was time for the demonstration.
Out came what my friend said was an old, soft bit of terrycloth that had once been a towel of some sort. It WAS very soft.
Off came the RTi6 grills, and my friend proceeded to "massage" his tweeters. I did notice that, the first time he touched them, they did seem to "pop" a bit - and that scared me.
Well, after the massage we popped the grills back on, and did the A-B comparison again. Well, I'll be darned! The difference between the two speakers had disappeared - and the sound DID "seem" to be sweeter on the very highest frequencies.
We listened for awhile - then I came home - not to "massage" my speakers, but to post this on the forum - asking -
ARE THESE GUYS NUTS? OR IS THERE SOMETHING TO IT? I'd love to hear directly from Polk, only I'm sure they'd just give me a stern warning, and talk about warranty violation, etc. SOO. . .
Anybody out there heard of massaging soft-dome tweeters? (NOT the aluminum ones!) And if so - did it do anything other than, well, soften them up? Hope to hear some answers, as my RTi6s could use a little smoothing-out! Thanx in advance!
