I was just about to post that all this damping was getting out of control
I did BTW. just receive to pairs of T50rps and I'm listening to the stock version as I type, and I find them very pleasing even in stock form, with the Jazz I'm listening to right now ( Lucky Thompson Quartet) the sound is sweet and flows very natural and it even seems to have better detail than the AKG K340 I used until these came this monday.
I mentioned the weight issue. It's a heavy issue. With all the plasticine, foam, and Dynamat these are too heavy to be comfortable for more than 15 minutes. So, I took #6 v2 apart, removed the Dynamat in the cups, the side pieces of AcoustiPack Lite, and about 1/2 of the plasticine...yes, you can have too much of a good thing. I left plasticine in place from the edge of the driver perimeter sloped down to the baffle rim. Re-installed AcoustiPack Lite to the bottom of the cups and over the 1" square in the central section opposite the intact bass port felt. Comparing in retrospect, the bass was not quite right probably due to some congestion from over-damping. The SQ is improved and the weight is no longer a big problem. Tomorrow I will remove 1 of the 2 layers of Dynamat around the drivers on the ear side which will further lighten them.
There have been several mods I really like and some not at all. Many are not better than the others, just different from one another. Still having fun with this.
