Lansaloy Surround Replacement (JBL LE-14C)
Hi All, I have found a white foam supplier on Ebay I have used to re-foam LE-8 drivers and passives. I am now working on some LE-14C woofers. Typically with surrounds only, I glue the foam to the cone and use a 30hz test CD to center the voice coil while adhering the foam to the basket (if...- ConnorFul

What to do with the voice coil?
Hi, Recently acquired a pair of Infinity RSa speakers. The surrounds need replaced as is customary for speakers of this age. Sadly, this is not the first time the surrounds have been "repaired" or replaced. The current surround is glued to the outside of the cone. I see a clear goop (silicone... -
ProAc Tablette 50 - bad surprise when I got them home
Purchased a pair of ProAc Tablette 50 mini monitors from a nice local couple. They'd wrapped the speakers in towels and had them stored in boxes for many years, and finally decided to sell them. They're pristine. But they stored them in possibly bad orientations in the box, on the side, and... -

I currently have a 16 ohm Coaxial Alnico just like an Altec 604 with resin dome tweeter, but it is not an altec.

Testing a KEF 103/4
So I’m looking to buy a set of used KEF 103/4 speakers. I’ve read a lot about the foam on the bass drivers failing and causing the voice coil to rub and fail, and the ferro fluid drying out in the tweeters.

Rebuilding KEF Reference 105.2
Hello everyone. I had the opportunity to buy a pair of 105.2, SP1118 S/N 1921A and 1921B. The seller mentioned that the voice quality is not good and I figured the issue was with the old caps, so I ordered a new set from Falcon Acoustics and replaced them even prior to connecting them to my... -
What did I do to my Dynaco A10?
I recently purchased a set of Dynaco A10s. Set everything up and all was good—sounded great. I decided to plug my turntable into the AC Outlet on the back of my Pioneer SX-880 receiver to free up the wall outlet. I didn't turn off the receiver before doing this. Made a godawful sound and before...- Wriley
