Stereo Speakers Repairs

I have a pair of old school realistic HOME stereo speakers. I repaired the foam surround on them, but Im still having a problem.

The one woofer in the speaker cabnit is fine , no problem.....but in the other cabnit when i turn up the volume past 5 i get a serious annoying HUMMMMMMMMMMMMMMMMMMM.

The speakers are rated at 150 watss, the power amp Im using is rated @ 300 watts. the speaker connectors are connnected right, and I know this because the connectors for each speaker are diffrent sizes, so there is no way to confuse the two.

It dosnt sem like the foam urround wasnt repaired right, even if so it should nt hum like that if it wasnt.....right?

First swap the left and right speaker cabinets and see if the HUM follows the speaker. If the HUM moves with the speaker, then the speaker in the problem. If the HUM stays on the same amplifier channel, then something else is wrong. If it is not the speaker then you need to look at you system. Hum is commonly caused by a ground loop or the shield of an RCA patch cord going bad. Do a good visual inspection of all of the RCA patch cords and make sure they are all seated. If everything looks good and it still hums, disconnect all of the RCA patch cords from the tuner/preamp. Turn the system on and select the different inputs on the tuner/preamp and see if it hums. If there is no hum, connect each component to the tuner, one at a time and try it to see if it hums. Keep doing this until you find the bad cord or component.

If it still hums with only the amp and tuner connected (nothing else connected to the tuner), swap the RCA patch cords between the tuner and the amp. If the hum moves to the other channel, you have a bad cord. If the hum stays on the same channel you have an equipment problem. Check the polarization of the AC power cords, some older equipment is not polarized and can be plugged in either way.

(I did this video some time ago, but I recently fixed my other speaker, and it prompted me to post this video again...) Over time, the foam rings ...

I recently moved a pair of electro voice interface series 2 speakers and a sansui AU X301/i amplifier that were just sitting a corner of the lounge room into my room and hooked them up to my xbox, tv and ipod. They were just sitting around because when we moved house we got a new surround sound system. I am wondering how good the stereo system is, because i estimate it to be over 20 years old. My late father bought them before i was born, and according to my mum he was a gear feak, so she reckons they are awsome. The thing is the large cones in the speakers are giving some distortion from medium to high level volume,so should i get them repaired or buy a new system?

You don't specify the specific model, but in general these speakers have a good reputation. See the link for some info.

While the speakers may be damaged in some way (e.g. a cone could have a small tear, or the cones might have got damp at some point) but there may other reasons for the distortion. I'd suggest connecting the speakers to another amp (e.g. your surround system) before assuming it's the speakers themselves.

If necessary replacement (8") Woofers are on offer on eBay for a reasonable price (See 2nd link) ... but only one day left to bid.

2 months ago I inherited Grundig Fleetwood Stereo system, made sometime around the early to mid 1960s in Germany, from my Great Grandmother who passed away in December. It has an AM/FM radio, a turntable for 78s, 45s, & 33s, as well as many sound preset buttons (including an option for stereo sound), and the speakers line the bottom portion of the unit. The physical unit itself is in amazing condition and has not been used in the last 25+ years for anything other than a table/decoration piece.
I was amazed to see that the radio still works on the stereo, producing very clear reception. However, the sound fades in and out during play; it starts off strong, clear, and loud, then slowly fades out, only to slowly reach its original volume again after several seconds. We have not be successful in getting the turntable to work, but I am more concerned with sound.

Who do you think I should seek to look into this problem for me, and potentially repair it so the stereo can be enjoyed again.

Any decent audio repair shop should be able to help you. If the unit hasn't been on for over 25 years some of the capacitors may have dried out or the electrolytic may have deformed. It's probably a tube unit and some of the tubes could be showing their age. Switch contacts could have oxidized over the years and need cleaning. The turntable has rubber drive parts that have probably deteriorated.

I bought a used car at a dealer, found out months later that it had no rear speakers and the speakers harness were cut. Took the car to the dealer, dealer said they weren't going repair the problem because they would have to replace the entire stereo harness.What should I do? Dealer knew the car had been modified and they didnt say anything about it before I purchased the car.

Go buy some new speakers,its to late now.

I just bought a 2008 VW Jetta and when I took it to get new stereo speakers installed they scratched the window. They are talking about having the window repaired or going through an insurance process to have the window replaced at the dealership. I have never had a window repaired before and was wondering if it would be a waste of time to do that instead of just having the window replaced even though it would take longer.

you have a brand new car!, it was there fault that it's scratched so insist that they get a brand new glass to replace it, thats your right.
