ADS l810 II’s- What’s up with these resistors?
Hello all. I’m restoring a pair of ADS l810 II’s that got on the cheap. Of course they weren’t in very good condition. I just pulled the crossovers out to have a look. As you can see in the pictures, there is what looks like powder from the sand cast resistors built up on nearby parts. Anyone... -
Technical Question about Pinnacle AC 550 speakers and Crossovers and Drivers
All, I just picked up some Pinnacle AC 550s, untested, for under $20. But, when testing them, on one speaker for sure both the woofer and the tweeter sounded "crackly" and a bit distorted. I have terrible ears, but this is what I'm hearing. So I switched both the woofer and the tweeter over to... -

Epi 301 crossover.
Hi all, I have a pair of EPI A300’s and m100’s. I love the 100’s, but the 300’s are way too middy and bright. I have to really tweak the eq to listen to them. Has anyone re-vamped the crossover or had this issue? I have re-capped them with the same values. Hoping to get them to have the same... -

DCM Time Window 1a's, two sets, very different sound and internals, anyone else ran into this?

ML-1C Recap Experience
I finally got around to recapping the ML-1C speakers. Here is how the experience went for me. I rebuilt the crossover of one speaker and put my family through some blind tests by sending a mono signal through one speaker and then another. They all said the rebuilt speaker sounded better.

I have a pair of Cerwin-Vega AT-15 speakers, with 15" woofers, and seek to recondition or otherwise upgrade them. I've refoamed the woofers and the other drivers are in good shape. The speakers are currently in use and sound good (not great as they could/should). Besides the crossover being... -
Using lower voltage caps in a crossover?
I'm upgrading a pair of crossovers and, as you may know, the bipolar electrolytic in many of these are hard to find 1:1 replacements for these days. Is it okay to use a lower voltage 50v cap in place of a stock 100v BP? I've been reading online and seeing mixed opinions between "never go lower... -

Vintage Ampex Crossover Cap Help
Happy New Year, I am a noob and would like some insight. I seem to believe the 1 capacitor is for the mid/high speakers, in a 2 way design. 1 mid, 1 tweeter. 1 woofer. I posted a photo of the capacitor, only 1 for these speakers. Can someone help me identify these as "original", and what I... -

Crossover Capacitor Quality and Kirchhoff's Laws
In almost every thread regarding recapping vintage speakers, people refer to capacitors which carry the signal "through" vs. those that "bypass" a driver and therefore don't benefit from a higher quality capacitor. It's my opinion, grounded (no pun intended) in Kirchhoff's laws, that this is... -
