"Mortite: Rope caulk is a great vibration-absorbing material for use with internal component chassis, loudspeaker baskets and many other applications (and highly recommended by Herbie's Audio Lab). Not advised for vacuum tubes, however. Mortite and other brands of rope caulk have a high temperature range of only 150°F (66°C). The material might hold up to the heat of small-signal tubes for an audition or two (which will probably yield good sonic results), but before long, Mortite will turn foamy, smoke and burn, partially vaporize and melt into a pathetic mess (similarly, Blu-Tak has very poor high-temperature range and will melt readily on vacuum tubes)." From Herbie's Audio Lab which specializes in vibration control. Tweaker also thinks this is great stuff for sonic improvement, good on wall plates also. Cheap and easy. It's been brought up before but the stuff is so good I thought it worth a repeat for those who have not tried it yet.

I bought loudspeakers that were SOTA back in the late 1970's. Sequarra 2 plus 2 W's. The frames and housings of all the drivers were heavily covered with rope calk.
Hi, I use Mortite for speaker gaskets and it works great! When I used it in my 1 room apt.to fills cracks to insulate my room some areas dryer out as the Mortite was exposed to the elements. When you make a gasket make sure the wooden area abutting the woofer or tweeter is primed or sealed.As in window glazing if you don"t do this step the wood on the sash will suck all the oil out of the linseed oil putty and it will crack and not last long.?..Mark Korda

it's also good on toast points
Back when I upgraded the drivers in a pair of Alon speakers, Carl Marchisotto recommended I use mortite to seal the new woofer baskets in place. The speaker was an acoustic suspension design so it was important that there be no air loss.
The seal around a driver in a ported box is just as important as for a sealed box. Ported box designs take into affect something called leakage and it affects the box design.
I've used DAP seal & peel on projects forever
it's a little more stealthy with exposed drivers
it can also attach grills intended to be affixed with glue and then they're easier to remove
YMMV no affiliation. etc.
regards,
Speaking of damping materials, museum putty is an often overlooked option. Much like Blu-tack and other poster tacks, but with a more aggressive bond.
indeed! I piped up over sealants, stick & peel won't do that in free air, it's got to be surface to surface ... Mortite is basically commercialized 'museum putty' if I'm not mistaken ... wouldn't surprise me if I was though
so, are 'We' OK Duster?
with regards,
Of course we are. I don't hold grudges in AA. If I were angry, I wouldn't communicate with you.
Posters go into my shite list when I give-up on them, rivervalley817.
thanks
Cheers, Duster
