Question about Audio & Video Receivers

1 Answer

The foam edge support for the eight inch bass speaker cones have deteriorated and now the "poly" cones are just hanging by their connection to the cone drivers. Same foam deterioration problem for the 12 inch bass reflex cones (paper). Can I replace the foam rings to support the speaker cones? What type of adhesive to use? Where to get the parts? etc. This speaker has seven separate speakers in one enclosure and are interwired with adjusting controls. I use the matched Kenwood amplifier etc so wish to keep the system going. Thank you for any suggestions. The speakers were purchased about 1986.

I have a pair of Jamo Laser 2000P speakers, and the rubber support for the bass units is perished. Where can i find the correct replacements?


I can't find any data to indicate the size of the speaker but if you search eBay for "(speaker size) foam surround" you will find various kits.

SUB WOOFER CONE SPLIT LOGITECH Z5500 REPLACEMENT CONE


you should just buy a replacement speaker and install it, replaceing the cone would not be cost effective, in fact you could buy a better speaker and get better bass out of the sytem, try www.martinsoundproducts.com they are in Cleveland and sell many great speakers in all sizes.

REPAIR CONE TEAR IN 18"


If the tear is large, or the speaker cone is brittle because of age, you might be best off having the speaker completely reconed. There are companies that offer the service, or you can buy replacement cones and do it yourself.

For small tears (an inch or so long), you can glue a patch in place. I have used a piece of a paper coffee filter as a patch, and plain white Elmer's glue slightly thinned with water. Put the patch over the tear and use a small brush to spread a thin layer of glue over it. Give it a day to thoroughly dry and you should be set.

I have found this repair to be more effective on smaller speakers than on large woofers, though. The woofer cones are more mechanically active. But I patched a couple of 15-inch cones that had been punctured for a friend, and they are still playing after a year. So it can't hurt to try.

A repair kit should solve your problem. Make sure you get directinos and follow them. For not much more you could send them out to be re-foamed. Bing or google speaker refoaming

I have a pair of custom made bookshelf size speakers that I love. They are older speakers that use french made Focal 7" dual voice coil drivers. One mid-bass 7" driver and one tweeter per...


Hi,
Well, fortunately it was the woofer that blew out. The reason I say that is because woofer material should have little to do with accurate reproduction in that frequency range. Since I don't know the model number of the speaker that was discontinued, I can suggest to you what can be done to get a satisfactory result.
1st If you have the model number on the Bass Driver AND Focal has the specifications. Go ahead and match the characteristics using THEIR data. The most important characteristics, besides the size of the driver would be the efficiency of the driver in terms of dB out. And the resonance frequency.
If these two are matched up closely, you should be good to go.
Focal is known to make good drivers, however, if you have to go to another manufacturer and you match the specs as above, then you should still do well.
If you get a newer Driver from focal, some of the characteristics may have been improved upon over the older driver. Such as transient response. If that were improved upon, It wouldn't sound really different, but it would seem tighter in the bass range.
One other thing I suggest. If you do as I suggest above and are pleased with the result, Go ahead and replace the woofer in the other speaker.
One additional point worth mentioning. Many of the foam surround speakers used in the old days in audio have failed because the foam has literally rotted away, as may be the case with your woofer. I know, as I have re-foamed enough of them. If you find a satisfactory woofer with a butyl rubber surround, it will never rot.
That would be the best replacement, as it would be permanent (if you don't badly overdrive it)
I've been an audiophile for most of my life, and I love music. I REALLY feel for you. I think that you will come out this just fine.
I hope this helps you,
Best,
Mark

I have Imperial 4 speakers circa 1971. One of the woofers popped the center black cap and is now fuzzy at moderate bass levels. Can I get a replacement speaker somewhere? Thx, Rich


I do most of my vintage audio shopping on eBay.

You could probably get a whole pair of them for less than sourcing the individual woofer.

Ends Dec 15, 201019:15:17 PST - Right now at $15.00 with $15.61 shipping.

Or maybe you just need to refoam them....

At $26.00 for this kit, I'd opt for whole speakers.

What kinda glue do you use on a blown speaker?


A blown speaker needs the windings replaced and re-coned. If you have deteriorating foam\cardboard type edges you an use clear silicone caulk from any home improvement store to fix small tears or detererioration. Tears and such on a large scale will require re-building.

I have 2 Cerwin-Vega speakers that stand on the floor Both have blown bass components and blown fuses. They have adjustable mid and horns and the bass is also adjustable. Can I replace these items...


Hi there,
of course you can replace the bass components and the fuses.
If you are not sure if the bass driver are actually blow try to replace the fuses first. You can easily find the fuses in any electronic components shop (like Radioshack or Maplin).
If the cones are blown they can be repaired (some specialists can do that) or just contact cervin-vega for the spare if available.

Substitute for Woofer p/n 141760


Hi there

Replace the foam for sure. It is always better than looking for another original driver to fit to the box, as they often have foam deterioration happening as well(spares are the same age as the originals) . A great idea(once repaired) is to use an artists paintbrush to apply "Armoural" a polyvinyl protectant to the foam. It will extend the life of it by at least double. They rot in hot humidity and heat environments and there is not alot that works better than that foam. I have done hundreds of speakers here in Queensland Australia. If you live in a hot humid area, there is probably a HiFi shop near you that does repairs to surrounds also. Good Luck

Do you have a source and knowledge for replacement of foam surrounds. holler back and I can help:)

regards
Graeme
