crossover rebuild

Howdy folks I’ve got me a mighty fine set of the aforementioned speakers that I’d like to recap and I wanted to ask you all for some advice on the matter. This is my first attempt at a crossover rebuild and I am not sure if replacing these caps would make any difference. I don’t have a...

Hello, I have a pair of Reference 60's in need of repair. I will not be doing the work myself but bring the speakers to a specialist. Aside from the re-coning that has to be done, I am wondering if the crossovers need work to, having read on the forum that these can degrade as well. Is it...

This is my first post, I'm fairly new to the hobby and am wanting to rebuild a set of mission 707 speakers. Picked them up for $10, they need foam on both woofers and I'd like to rebuild the crossovers. Figured this would be a good speaker to start with. Where do I start?

Hi, I got a pair of Bose 601 Series I speakers from 1977 that havent been used for more than 20 years. I've taken the speakers to a technical service to restore the foam to all the woofers and tweeters and he told me it would really improve the sound to change the crossover for one new...

FYI this will be my first real speaker repair attempt. I am looking for some guidance on testing and repairing some Kappa 6.1 Series II’s that I just acquired. I picked them up off of Craigslist for $50. As one would expect from speakers at that price, the surrounds are shot, the grills aren’t...

So I have a pair of Polk Audio RTA 12 speakers which I purchased around 1981 or so. Since they are 37 years old I thought they would benefit from a crossover rebuild. I've never attempted a rebuild like that, but being handy with a soldering iron and having some understanding of electronics I...

Hi All, I have used this forum as a resource for a while now and I would like to contribute by starting a thread to document my experience with the HPM60's. I found a pair at my local Goodwill last year; paid around $75. After some minor maintenance I was able to get them going and have had fun...

I bought a pair of Cerwin Vega XLS-215 s with a little bit of shipping damage to the cabinets for a great price.. Stock they sound a lot better than I expected. It seems that the newer CVs sound way more balanced and refined than their old stuff and still go like @#$%!!! I think that they were...

So, I've got a thread on here restoring a set of CV Cerwin Vega circa 1975 T15 s. Have (I think) isolated a capacitor as having blown; really avoiding any and all soldering "sittings"; ideally would like to know what the capacitor I think is fritzed is (its the big silver one on the board...

Not sure if this belongs here or in DIY.... I'm working on crossovers for Realistic Electrostat 2s and need to replace the resistors (speakers, not power supply). I'm having a hard time finding exact replacements in my stash. I'm trying to do this with what I have vs. ordering — the shipping...

Greetings everyone. Does anyone have a safe modification to the cross overs in the Thiel CS 1.5 speakers to improve their efficiency? I have read that in terms of an 8 ohm equivalent, their efficiency is just over 83, and they do take a lot of power. Doesn't seem to be an obvious reason for...

Having already purchased an awesome pair of Bozak 301 tempos, I felt a need to grab a matching pair of 302a for $290 on Craigslist. They are stock 1966 so they have the aluminum tweeters. Cabinets are in excellent condition. Drivers work great. One major problem, they don't sound nearly as nice...

I'm restoring a pair of JBL 4311b, and even with a few broken drivers my dad walks over and says, "these sound kinda like those MCS speakers we have upstairs". He's right. While the JBL's have much more coherency and clarity, the 12" woofer feels a lot like the MCS 683-8227 12" woofer. These...
