    Peavey Black widows not suspended correctly.

    Hiya, I recently bought a used pair of 4ohm 15" black widow drivers as spares for my Peavey hisys5xt cabs. On opening them, apart from a strong solvent smell, on examining them one is almost at the end of its excursion towards the magnet and the other almost all the way out (could they...

    Altec 808-8A horns restoration - can these be saved?

    Hi all, I recently acquired a pair of Altec 808-8A drivers with N809-8A crossovers from an old railway clear out up north. Needless to say they looked pretty rough but I felt they might be worth a gamble for 100 bucks. In fact “rough” might be a slight understatement, they appear as though they...

    Can anybody identify this aluminum cone driver?

    Hello everybody, Does anyone happen to know the make and model of this aluminum cone driver? There are no markings or part numbers anywhere on the basket or magnet. It's resistance reading is 7.4 ohm. I pulled it out of a Joseph Audio RM20 speaker cabinet that someone tinkered with at some...

    Both drivers go higher in freq

    Hello, I'm new to this site, but I've been into audio for a long time, and am even making my own album! I've created an account to post about a peculiar problem. I have these very cool speakers "ATL CELEBRATION" and they have this problem where both the bass and the tweeter play at a slightly...

    Can I install passive radiators into a speaker box with regular full-range speakers?

    I'm hoping to build wooden enclosures for these PC speakers I have. The drivers I'll be using will come from 2 different 2.0 PC speaker systems, and I'll be putting one driver from each into each "new" enclosure. I would also like to put passive radiators into the new enclosures. I've heard in...

    MCS 683-8228

    Earlier this week, I bought a pair of 8228s at a thrift store for 80 bucks, not knowing anything about them prior to this site. I was amazed to see the amount of "enthusiasm" on these speakers! The Cabinets are in decent shape, 8/10. The grills are attached, but could be fixed up. 8/10. The 12"...

    Why did Vintage SEAS Rubber Surrounds Hold Up Fine For Over Lifetime?

    Something that I was curious about, is the Rubber Surrounds used on Seas drivers. Used on the 1960s Beovox Line, and Dynaco Line of Speakers aswell. As you know, rubber this age is almost never going to be ok. Its usually dry, cracked, melted, or anything in-between. I have seen many of these...

    Should I use this passive radiator?

    I have a 2.0 PC speaker system, whose drivers have a diameter of 70mm (that's the diameter that actually moves, if that's of any use). Will the passive radiators shown below be suitable for these PC speakers? I've read elsewhere that a PR should have at least the same diameter as the driver, but...

    headphone upgrade

    So I had a thought. was looking on e-bay and found a bunch of Pioneer se-205 and 305 for cheap. Then I found that I could also buy the drivers from a set of Sony WH-1000XM4 for around $10 per side. so $20ish plus shipping. Is this a dumb idea? Is it even doable? The Pioneer's have 45mm drivers...

    Troubleshooting a quiet tweeter

    Hey all! So glad I found this forum as I am at my wits end! I have an old NAD 3020 & a set of TDL Nucleus 1 speakers that have been in storage for a few years since moving home. I just managed to finally get my hands on them & after repairing a small tear in one of the mid drivers (using a...

    How can I Determine Frequency Divider connections?

    I am seeking a way to determine which output terminals of speaker crossover networks feed which components. So, what I have is a set of 3-way frequency dividing crossovers, but I need to figure out which wires should attach to which driver components. There are no indications on the boards as to...

    Cone problem with Vintage Ampex JBL Driver

    Greetings all, I just received a late 50s Ampex-by-JBL 8 inch driver from a 621F integrated amp/speaker system which @Plimpington2 sent after helping him in repurposing the amplifiers for general use. These were used in the 620 and some of the later suitcase amplifiers as well. On its way...

    1060 - Can't get half voltage at output caps

    Hi, I have done this model more than once and don't understand the problem. It's fully recaped as usual with Nichicon / Elna. I replaced all 2SC458/1000 on the phono stage, as well as both 2SD438 on the output board (the two new ones I have in stock have a gain of 152-155 so no idea if this is...

    Anyone recognize this driver manufacturer logo?

    I was wondering if anyone recognized the logo on this driver? I found it in pair of speakers that were "manufactured for sound studios". More info at the thread below. https://audiokarma.org/forums/index.php?threads/speakers-manufactured-for-sound-studios-newark-delaware.880010/

    Yamaha NS-430 high pitch sound from mid-range drivers

    I recently acquired a Yamaha system which consists of a CA-410 amp, a CT-410 tuner, a YP-211 turntable and a pair of NS-430 speakers. I traded everything for my Akai AM-U02 receiver. I didn't test everything yet but I plugged the speaker to my Toshiba SA-300 and I hear a high pitch sound from...

    Goliath II sub sounds "gravelly"

    I have a Goliath II sub that sounds gravelly or scratchy. It has been re foamed but I don't think it has been re capped. Is it just a bad foam job or would some new caps clean up the audio? Or is the driver toast?

    Need help B&W speaker short?

    I have a set of beloved 1995 year B&W DM640i with 6.5” yellow Kevlar midrange 4 ohm. When the speakers were playing, the midrange frequencies were phenomenal. Recently one of the midrange speakers stopped playing. The speaker plays if I depress the cone in about an 1/8” of an inch. I’m getting...

    G-9000DB Distorted sound on left channel (Solved)

    I have this receiver for 6 years now and had no issues with it. Last week the left channel started sounding distorted, even on headphones only, which means this is happening prior to the amplifier side of the house. It starts getting distorted after 10-20 seconds. I did notice that without...

    National EAS-20PW55 drivers - what speakers are they from?

    Hi guys, I'm trying to find some National/Technics EAS-20PW55 drivers and am having a pretty hard time. What speakers did they come out of? Maybe I'll have better luck searching that way (unless someone can put me on to some?) http://audio-heritage.jp/TECHNICS/unit/eas-20pw55.html Thanks...

    Vintage Sennheiser HD 414 behaving weird

    I got myself a pair of Sennheiser HD 424 some years ago. With aftermarket strange blue hard foams (see photo) which I replaced with NOS yellow ear pads. Lovely headphones to use while at work, etc. Fast forward to last week. Visited the local thrift store and found a pair of Sennheiser HD...

    Woofer is stiff and scraping when pushed

    I recently acquired a pair of Infinity CS-3007 speakers and was in the middle of a refoam job when I realized that 3/4 of the 8" woofers seem to be blown (I'm new). Since I wasted a bunch of time and money on them already I figured I'd make sure by posting here. When I push down lightly on...

    Ariston Acoustics Image problem

    I offered to repair the mid/bass driver in a friend's Ariston Acoustics Image speaker. She noticed a lot of distortion coming from one speaker and, upon removing the grill it looks like the cone took a hit that ripped the rubber surround. My friend blames her rowdy nieces for the damage but good...
