Hello all,

I hope you excuse the poor quality of the pictures, but i had them done with my outdated camera and was more concentrated on the work part than on the taking pictures part.
So with no further introduction....

The initial state. The whole wire jungle. One broken speaker holding screw, solved that with a lot of epoxy.



Decided to pull everything together as i did not need additional rattle caused by the cables. Sprayed some wd40(deoxit equivalent) on the volume knobs just in case.


As i had some Silent Skin car insonorizant around i have decided to use it on the tecsonic.
I payed a lot of attention to the details, and strengthened the best i could.





As the tweeter sound goes linear and does not need a speaker box, decided to go over it.



The result:

The sound quality had much improved. Did not gained bass, but i gained some volume without distortion. Also, gained 2-3 kilos as i used 6 sheets of SilentSkin. For the nearly 6 hours spent on this one, i think it was worth it. I did not soundproof the back cover, because of the holes in it.

Comments/questions are much appreciated.

Very interesting project. Why not to do it with the back cover? Do those Jumbos really need those holes on the back? Didn't know, that they are SO empty ...
p.s. people say, later wd40 does more harm than good job for electronics.

Well, i don-t think they really need those wholes but if i would cover them, then i would be in a rather sticky situation. Soundproof material is made of one sheet of aluminum and one layer of black tar. If i would cover it, the tar would get out trough the holes.

why not to add a big piece of black plastic on the inner side of the cover, before adding that material on it? Maybe tar + very flat surface = better result?
I wonder, if enyone have tryed to improve Hitachi's TRK 8190E sound..I love this design, but the sound is . Could such material help, or that model is simply hopeless?

The Hitachi is much smaller. I would use on that kind of enclosure only Brax paste. It could not get worse, but if the model is stiff as i remember it is, then it won-t do any good either. You can try if you want.

The next one on my list is the Philips D8734 as i still have some silentskin left

what about filling the external holes gaps with silicone to seal it proper and get a nice finish if the holes are not needed but im sure you would need some kind of outlet for the speakers to work to there potential could always rebore to suit yourself to where they go i dont know if we can get that stuff over here in uk but if you got a link be most helpfull on the stuf you used cheers daz

I am sure that you can find some of this products or similar ones pretty much everywhere.

Looks like you did a really nice job there, I love it when people spend hours and hours on making a beloved boomer that bit better, I'm on your side all the way, well done.

yes thats a pretty good idea, and you did a great job man.

Thank you driptip!

Will come back with more pictures from my projects.
