I have read that covering the backside of horns with rope caulk helps reduce unwanted vibrations. Is this recommended for the SEOS kits? Is there a product out there that is more clean/self contained? I don't like the idea of having rope caulk crumble/droop/whatever off inside the speaker.

Most of the recommendations for the need to damp the rear of horns are unfounded. Their shape and construction makes them naturally very resistant to vibration.

I measured before and after applying deadening material to the back of a SEOS-12 WG and saw no difference in FR or distortion. They're thick enough that additional deadening isn't required.

Exactly what I needed to hear. I am prepping for 3 Alpha-12 kits, and wanted to know if I should throw anything extra in to my Amazon cart. I'm relieved to hear that I don't need to.

Thanks BillF and Face2. smile.gif

Couple more questions:

Is this good for lining the walls of the speakers? Is one layer enough? (It's 2" thick, apparently)

I've never tried it but it should work OK.

FYI I used about three layers of duct tape on my 12" SEOS waveguides for no scientific reason whatsoever, except that what I tapped on it with a drum stick, the duct tape deadened the sound, and I determined that was a good thing. smile.gif

To the point of the thread, Mr. Rebel; did you replace the wiring?

This works well, from what I've read, almost or better than fiberglass of equal thickness. I've purchased a few cases already.

Good question! eek.gif

I'm not sure, but I think two threads were run into one on my browser! I could swear I was replying to a thread on wiring subs with a long run of wire! Sorry about that.

At least I got PART of the thread responded to properly with my duct tape answer. rolleyes.gif

I know what thread you are talking about. "Wire size for passive subs.... did I mess this up?"

But if it makes you feel any better, I ordered this in preparation for this build: https://www.parts-express.com/wired-home-skrl-10-100-10-awg-ofc-speaker-wire-100-ft--100-029 biggrin.gif
