Golden Ear award for $55 speaker tweak


In the latest issue of The Abso!ute Sound, Robert E. Greene honors "Diffractionbegone" with a Golden Ear award. Quoting from the text (page 36 of the June/July 2008 issue): "If your speakers suffer from tweeter diffraction-effects, these elegant and inexpensive felt devices will make an improvement all out of proportion to their low price."

Diffraction can degrade not only imaging and timing but also clarity. You see, the ear is very good as masking (ignoring) a coloration that arrives at the same time as the original signal, but it is very poor at masking when the coloration arrives at a different time (I learned this from conversations with Dr. Earl Geddes). This product addresses several real, audible problems that are present in most speakers.

The felt pads are custom-cut for your specific speakers, which is a nice touch and pretty amazing at the price. And note that this is by far the LEAST EXPENSIVE product to be singled out for a Golden Ear this year.

Congratulations to designer and entrepreneur Jim Goulding. I think he sells them through Audiogon as well as through his website, and it looks like the price may actually be only $49.95 plus shipping. Support your local 'Gon and buy through the site. Come on - you probably blew more money than that on shipping last time you bought or sold a pair of speakers! I sure did.

Those look like what Spica used to use on their TC-50's (I'm sure I've seen the same thing on other speakers as well). I can't help but think it looks an awful lot like the stuff you can get for your furniture at Home Depot to prevent scratching the floor. Man, Home Depot's becoming a regular audiophile resource center! Hey Duke, I seem to recall seeing your statement speakers on someone's Golden Ear list in this issue too. Correct me if I'm wrong, but if so a big congratulations to you! That's a pretty significant achievement.

While I use a felt material on my VMPS I installed last year, I was inspired by my 25yr old Teledyne AR9 speakers so its not new or any revolution but all the same is beneficial........you can buy adhesive felt sheets at a hoby store or even at Walmart.
Looks like what many speakr manufacturers have been doing for a while. Wilson Audio is one example
Installing felt around the tweeter is old hat. It's a simple effective way to roll off the highs. I considered doing it on my Aerials when I had a Krell.
I think my experience captures some of the earlier posts. A poster with the moniker "Bald Eagle" at the Vintage Asylum at Audio Asylum suggested this tweak. I bought some self-adhesive felt at Home Depo, sized it, and placed it along the sides of the tweeters of ADS L710s I used to own to a height of about 1/2-3/4 inch. I believe that the sound improved.
