....and throw away the key

actually, you may have hit upon something there - what would sound better - textured, or smooth wallpaper..?

painted..?

 

funnilily enough i have dealings with the odd acoustician through my work. they tend to be more industrial types - who know's next time i try to remember to ask about the dots

 

I've always found these highly amusing:

And the price of them even more amusing!!

They will lower the resonance point. Part of measuring a driver involves altering the mass in this way but I don't know why you'd do it after the driver is in a box as the box characteristics will no longer match the driver properly.

 

Exactly, it would fudge the port tuning and lower the break-up point, would it not? Increasing the driver mass would also damper transient response. Hell, it would even change the impedance curve I expect.

You still think we have no reason to doubt them Zanash?

 

It lowers the driver resonance point so in theory it may go lower if your lucky but yes it would be slower. The port should still resonate in the same place but it probably wouldn't be the right frequency to help the driver anymore. If you have really poor speakers it might help but I'd have thought it'd be more pot luck than tuned. I wouldn't have thought having such an uneven mass would help much either.

 

Indeed we do.

 

The 'great cable debate' has been sorted? Did I miss some amazing revelation? Who was right?

 

Have IQ suddenly dropped .......?

I'm not supporting sticky dots .....far from it .

All I want is to allow the idea to be aired, not strangled by the nay sayers.

Oh yes............... for those of you who must have sleeped through the 80's and 90's ....the cable issue was sorted .....

any half decent system, can, will and does show the difference between cables ...if it does not it, by definition is not Hi Fi.

this can simply be proved by going doewn to wilco and buying a suitable length of their bell wire and substituting it for you latest designer cable. Still can't hear the difference ? .........probably means you problems else where.

 

Oh, you poor pet! All those nasty, nasty, strangulatory naysayers unsettling poor diddums!

True, the cable issue was indeed sorted - lots of folk have overheated imaginations. Yes, tried normal lighting flex, no, no difference, no hearing is fine. But, amen and hallelujah, Brother, give us that ole time religion!

(How's your strangulation going?)

 

I am all for supporting new and unusual ideas... but I don't see any sense in supporting ideas that go against well known physics such as increasing mass to lower the resonant frequency and the implications this has on a loudspeaker design.

So I support new ideas and inventions but NO I don't support people who are clearly just trying to rip the public off.

As for cables I think the question is, do different cables that are ALL capable of adequately handling the signal make an audible difference? Bell wire doesn't take 100watts at low voltage very well.

 

here are some dots that work very well for stimulating the temporal lobe

I won't comment on the effectiveness (or not) of these dots or of Beltism or a number of other 'tweaks'. I wonder however, how substantial any changes have to be before their effects are significant compared to the differences in our perception of sound quality as a result of mood changes and the like.

Am I the only person who notices apparent fluctuations in sound quality due to my own mood rather than any changes made to the system?

 

Would they be microdots?

 

I don't think so. The dots are probably applied with the finger tips. Petroglyphic dots could be and could even have a somewhat tenuous connection with music and *really* good bass.

 

It was an itsy-bitsy, little squeaker, yellow polka dot loudspeaker
That he played for the first time today
And he said making speakers slightly dotty wasn't really slightly potty
It made a difference in sound night and day.

 

And before I forget, I give you Yayoi Kusama, avant-guardeista extraordinaire for the last 70 years

the dots are not new

...there was a guy in the mid-80s who had the idea of placing small squares (!) on hifi equipment would make a difference - he mortgaged his house because he believed in it so much. Can't remember the principals of what he was doing - anyone remember.

Can I also check on the rules in this thread? Are we dismissing stuff without independent data now? In the ATC thread we needed independent data because all we had was opinion? Oh, really, I see, I get it now.....

 

They should have stuck with the rubber gloves.

 

If I said, "you can improve your sound by placing a fresh cow pat on top of each speaker, and I am selling these sensational audiophile-grade cow pats for only £100 per pair," would you demand independent data to see whether it worked?
