Know of a "Dirt Cheap" tweak?

Sabai, I never said Franck Tchang’s diagram wouldn’t work at all. In fact I specifically said that a post or two ago. It’s because you’re close to but not exactly on the 6 dB peak, only at the 2 dB or 3 dB point or whatever. Close but no cigar.

Pop quiz: why are even tinier little bowls also a good idea. 1/2" bowls are what, 1/4 the volume of the 1" bowls?

footnote: Sabai, you forgot to mention Machina Dynamica’s Codename White Poppy acoustic resonators, which have been around for what four or five years? See if you can guess the material I use for my resonators. Betcha can’t. Hint: Machina Dynamica’s Tru Tone Wall Outlet Covers which have been around for 10 years employ the same material (and are also resonators!). There is also Golden Sound’s Acoustic Discs which are not bowls but are basically the same general idea. They’ve been around more than 10 years.

cheers, everybody

geoffkait,

When you state that "I never said Franck Tchang’s diagram wouldn’t work at all", may I respectfully draw attention to your statement that Franck’s placements "are doomed to FAIL for the knock-off attempts of cheap DIYers ". And to your statement that " ... you’re only guessing if you don’t use a SPL meter." I do not think that Franck Tchang was just guessing. I think he went about this very methodically. Otherwise, his placements -- even for so-called "knock-off attempts of cheap DIYers" -- would not work as well as they do. In fact, if they did not work so well across the board I am sure this would have been reported a long time ago starting with Stereo Times and 6 Moons, then moving down the line to Zilplex, Synergistic Research and Audio-Magic. But such is not the case. On the contrary. So, you and I respectfully agree to disagree.

I have no experience with your resonators so I cannot comment on their effectiveness nor can I compare them to resonators made by other makers -- or my own DIY version. But may I respectfully note that you earlier mentioned that you "... started designing and selling acoustic resonators before acoustic resonators were even a gleam in Franck Tchang’s eye ...". But in a more recent post I note that you refer to your resonators being around for 4 or 5 years. Franck Tchang's resonators came out in 2004.

Would wrapping any cables with yellow Teflon plumber's tape have any effect? If so, why? I know its a strong dielectric. Does it shield cables near each other from interference. Haven't tried it, just wondering if anyone has.

Yours Aye,

kavakat1,

I used to use ERS paper around cables but the SQ reacted badly.

geoffkait,

I just checked your own placement diagram on your site. I see you are using some of the same placements as Franck Tchang.
