Big fan of the stuff here. I use it on lots of stuff. Could you comment on what it did or didn't do to the speakers? Also, while not expensive it isn't cheap. Where do you buy yours?

And I thought I was the only one still using the Deflex.Specifically
what I did to my 2 way speakers were to continue off where the designer started on them. He had 2 Deflex panels glued inside the speakers on the back wall directly behind the drivers. The cabinet is about 39 inches tall by about only 6.5 inches wide, or 5.5 inches on the inside of the cabinet, and only about 7.5 inches deep or less with a port hole about 22 inches up from the bottom. The speakers are 2 ea. 5.5 inch drivers for the woofer midrange reproduction and a ribbon tweeter which goes out to 40k. There is no crossover in the speaker only 1 cap. across the tweeter going to the internal speakers + binding post.
The cabinet was stuffed with cotton white stuffing for atleast the first 22 inches of the volume almost up to the first speaker driver.
I carefully reached as far down the speaker as possible and removed ALL THE STUFFING? Why because that is what Deflex recoomends once u install the panels. Well I proceeded to install 6 additional panels per speaker in the cabinets. These Deflex panels were 5.5 inches wide by about 9 inches long which worked perfectly for the internal dimensions of my speakers. I had spoke with the designer of the speakers and he stated he wanted to use more Deflex, But could not due to the additional cost involved. So I just took off where he left off and installed 2 and a half additional panels to the back of the cabinet and installed 4 panels across the sides of the panels including the bottom top side of the cabinet. So the top half of the internal cabinet is completely installed with Deflex all the way down to about 7 inches below the woofers port
leaving the last 7 inches not covered only because I could not reach down there without tearing apart the cabinet; and this I did not want to do.
Now was it worth the trouble and expense. Yes indeed! I was up to 3 A.M. Listening to all my CD's again.The imaging was rock solid 3D. i COULD HEAR WAY BACK IN THE SOUND STAGE, AND THE SOUND BECAME MUCH MORE NATURAL. I was able to hear the decay of all notes much clearer,and the dynamics increased as well. I was able to hear the prounounciation of words from vocalist much more clearly too. Speed and transparency improved and it was interesting that all of this carried over as well when I damped the chassis internally in my dvd player. So the cumulative affect has been remarkable to say the least.
The small Deflex sheets cost me $6.95 each and I picked them up thru Michael Percy's Web Site.
So I hoped I answered some of your questions.
Thanks for inquiring

Happy Listening
Thanks for the detailed post. I'm going to do deflex to the cabinets when I do the x-over upgrades.

What glue did you use to hold the Deflex ? I have used it for years but never found a glue to hold it securely along sides or under the top panel.
I have always got mine from Partsconexion.

The exact glue I use is DAP Weldwood Contact Cement.
This stuff is very sticky. Before using u must wash the deflex completely with a hot water and mild dish detergenet to take out any oils from the panels and then make sure it is air dried completely.
Then the Deflex will feel tacky and somewhat sticky this way.
It says on the small one ounce bottle I bought that this stuff bonds on contact.
Use on wood,rubber,leather hundreds of items, and that its a durable water resistant bond.
If it still doesn't stick then I will apply to the surface I'm trying to stick it on as well.
The stuff is kinda messy But really works, But make sure that once u stick it on the wood don't move it at all or it will loose the good tight bond on the wood.On the bootom top I took a piece and ran it from the top side about 3 inches down the side and ran the other piece right to the opposite edge corner and it created a nice seal for me that way.
Well good luck. This Stuff Is great and I think although somewhat expensive this has been by far the most significant tweak I have ever done in 30 years.

Thanks, I never thought of washing it, it just seems to oozs oil. I had a piece laying on top a CD player once, when I removed it to sell the player it left a nice big square wet looking stain on the player that could not be removed. Luckily the buyer wasn't very picky.
