Rated 5 out of 5 by from It did the trick better ...I already had some foam gasket tape that wasn't quite accomplishing what I needed done. Got the caulking quick enough from P E ...and, abra cadabra, the sealing stuff was just what the 'doc' ordered .... Thanx abunch !!

Rated 1 out of 5 by from Stuck forever........After purchasing this item and installing it, I needed to get back in the cabinet. I had to hack at the edge of the mounting hole o the speaker with a putty knife to get the speaker back out. I CLEANED IT BACK OFF, and reinstalled without the caulk and used felt instead.

Rated 5 out of 5 by from EASY TO WORK WITHAt this time with limited usage, I am afraid to go to far out on my evaluation's. I plan to try some on the rear deck speakers in my car, as that might give an idea of long term flexibility.I also have a couple projects that have been stalled by some surgery, so more data to follow.

Rated 5 out of 5 by from Use this for everythingI have now used this caulk to mount my 3" mids in my dash, my 6.5's in my doors, and some 5 1/4" coax's mounted to a pair of saddle bags for a friends motorcycle. It is easiest to work with if it is a little cold (I actually threw mine in the freezer for a few minutes before using) so it makes it easier to get ff the paper. Be sure you don't squeeze the box or paper wrappers at all, or it will be hard to get off the paper, but that was my fault. Also be sure that when screwing down your speakers, when the caulk makes contact, screw it down slowly to give it time to "squish" so it can spread and do it's job.

Rated 1 out of 5 by from Speaker Sealing Caulk not recommended / Speaker Sealing Tape recommendedI have read several positive reviews for the Speaker Sealing Caulk, but my experience has been the complete opposite, so I must respectfully disagree with other reviewers and share my negative experience, and also recommend an alternative product that I have found to be superior.Although I wanted to like the Speaker Sealing Caulk because it was cheap and easy to apply, in my experience the performance is completely unacceptable. The Speaker Sealing Caulk is very easy to apply, but it simply doesn't work as intended. The primary issue is that the caulk is very soft and remains soft indefinately, so it continues to "squeeze out" from behind the driver flange indefinately. The caulk actually "flows" under pressure from the fastener torque, and as the caulk is squeezed out from the driver flange the fastener torque and driver to enclosure interface continues to degrade over time as the caulk very slowly squeezes out; re-tightening the fasteners back to the required torque simply squeezes out more caulk and restarts the degradation cycle.The Speaker Driver-to-Enclosure Interface is so important that Fastener Torque alone has dramatic impact on loudspeaker performance (several dB# and this impact is measurable, audible and well-documented #see Loudspeaker Design Cookbook#. Since the Speaker Sealing Caulk cannot provide #nor maintain) the necessary driver-to-enclosure interface that proper fastener torque provides, this product does not function as intended and I cannot recommend use of this product. I urge other speaker builders to use PE's Speaker Sealing Tape in place of the Speaker Sealing Caulk.I can recommend PE's "Speaker Gasketing Tape" without reservation because I have found it to be a completely effective product. It is closed-cell foam with very aggressive adhesive on one side, so once the fasteners are properly torque it does not continue to compress over time, and it easily stays on place during assembly. It compresses to a very dense gasket interface between driver and enclosure and maintains this interface quality indefinately.**note: remember that the Speaker Sealling Tape does not compress completely and requires a very slight increase in driver inset depth when routing your enclosure for flush-mounting your drivers.

Where's the instructions?

Got your product with no info, no info if there is any harzard to handling properties! What do you use to remove any that gets on cloth, wood or leather/Tolex?
Asked by: ETimms1954
I haven't seen instructions included for this product, but it is easy to use. you simply lay a bead of it around your speaker flange as shown in the PE picture above. You may also want to check out "Plato Indy" review of the product. I can't recommend using this product; in my experience it is messy and ineffective. I recommended an alternative.Cheers,

How do you get the old stuff off so Ican replace the speaker?

Old PA cabinet has seal on the old speaker that's sealed in. How do I remove the old speaker without damaging the cabinet? It's the same type of seal!
Asked by: ETimms1954
If I understand your question correctly, you are saying that your loudspeaker Driver is still securely fastened to the enclosure: Sometimes glue is used by OEMs and sometimes old gasket material simply compresses and adheres over time, in both cases Driver removal can be tedious, but still doable. I typically take a large, flat, flexible knife and very gently tap under the edges of the driver, going around its entire perimeter to cut loose all the glue/adhesive/gasket between the Enclosure and the Driver, as well as I can (Be patient and careful during the whole process). After loosening the bound between Enclosure and Driver, I use a miniature version of a nail puller (or miniature "wonder bar" as they are sometimes called) and lightly tap it round the entire perimeter of the Driver until the bound is finally weakened to the point I can gently pry it free and remove the Driver. Stamped steel Driver baskets/frames can be easy to bend, so take care not to pry too hard; care and patience are usually rewarded with success in this process.Cheers
