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... -

Marantz 2330 driver subs
I have a 2330 on the bench with driver subs I never saw before. Instead of 2SA839/2SC1669 I see 2SB596/2SD526. The spec sheets say these subs can take half the voltage as the originals. Pretty sure I should replace them - even if working?- ocdecio

Everything else tested good. I used 2SC1060s for the...- Richard P

Driver question, EPI M202 specifically
Hello, I have read all the M202 posts I could find, and poked around other restore threads. I don't see an answer, or I am searching incorrectly. I have finally opened up my M202s to start restoring. I am hoping to just re-cap, clean the dial, and replace the binding posts. If the drivers are... -

Is anyone else super OCD with their speakers?

Hey, so I recently got a driver that claims to be an LE5-6, however it very clearly isn't. The only thing it has in common with my other LE5-6s is the casket and labelling on the magnet.

Hello. I'm curious to know why is it so many models of home speakers have separate grills only covering the midrange driver, or just the tweeter, sometimes both, used on 3-way (or more) speakers. For 2-way speakers, the tweeter? Why not protect the woofer too? I'm not referring to the main... -
