Question about Audio Players & Recorders

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.

Repair of speaker


You can have your cones re-foamed by any speaker repair shop. You can even do it yourself, there are many places that sell kits to do that. It's easy, I've done it myself. Here's a source:

HI CAN YOU PLEASE TELL ME WHY MY FENDER RUMBLE 100 BASS AMP DISTORTS AT LOW VOLUME? EVEN THOUGH THE SPEAKERS IS NOT BLOWN


A common reason for 'distortion' with all bass amps can be either that the screws holding the speaker unit to the cabinet have worked loose or that there has been a build up of dust particles in the corrugations around the edge of the speaker cone, which rattle especially on the lower notes.
The solution is simple - remove the front grille and check the screws are tight. Use a vacuum cleaner to remove dust from the rim of the speaker cone.

Hi, I am looking for a replacement bass cone for a pair of Tannoy 611's mk1's. I had them from new in the early 90's but a few years back, my son picked out all of the foam that joins the plastic cone to...


If you found second hand 605s you can swap entire sub speaker. Your other option is check your local yellow pages for a pro audio repair shop that does re-coning. Re-coning is a specialty operation and it's not a procedure for the novice. You can also check online for re-coning services.

Ok..... I have some Wharfedale Modus 8s. My question is, is that the base speaker is crackling a bit. typically when you don't have enough power the tweeters will clip first and go out. perhaps i did...


Dunno how old they are, but I just had an 11-year old pair of woofers re-edged because the foam surround and the adhesive had deteriorated. Upon close inspection the foam surround was noticeably pulled away from the cone in a few spots. Unfortunately, if there is an age-related issue with materials beneath the surface that you can't see, you'd have to pull the driver to check it out.

It wasn't until I turned my bass up loud that anything sounded wrong, which precipitated looking for the culprit (quickly found).

It is rip in to little piecies


It may not be worth the expense, but if the cone or surround are torn, they can be replaced by a speaker repair shop. I just had a pair of JL 10W6's re-edged (the foam surround around the cone deteriorated after 11 years), and the repair cost $100 for the pair, including parts.

My 12 L7 the rubber came off the cone and doesnt hit as hard what kind of glue would fix my problem


Hi, Jr.

I'm sorry, but glue will not fix this problem. When the rubber or foam edge of a speaker breaks down or deteriorates because of age, it becomes almost like dust, which is why it cracks and then breaks apart and falls away from the speaker. The only way to fix it (besides replacing the speaker) is to replace the edge, or "surround". At this link, http://www.simplyspeakers.com/All-Foam-Kits_c_118-1-3.html, you will find a kit that you can buy to repair your speaker for about $30. The standard 12" repair kit will work if you have an 'angle cone edge attach' type speaker (see the bottom of the page for a picture of what this means). This page, http://www.simplyspeakers.com/speaker-repair-foam-edge-replacement-instructions.html, will show you step by step how to use the kit to repair your speaker.

Good luck, and please remember to rate my help.
Thank you for the opportunity to help you.

One of my kicker cvrs rattle really loud at high volumes


It could be the foam edging where the speaker meets the edge of the cone. Rubber works better than foam, and I believe kicker uses foam for this model. Check for any missing screws because sometimes air leaks make that sound you hear. also try turning down the amp a little bit

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.

Subwoofer Bass Level Problems


What is your sub stood on? If it is on a piece of furniture then this could be the problem. Bass frequencies travel further than higher frequencies due to their longer wavelength and will also be transmitted through any solid objects the speaker is in contact with. The solution is to mount your sub on a piece of foam to provide some damping.

Also if your sub has a port (a hole) on the back or side this needs to have a good 3 or 4 inches clearance from nearby walls or panels.

Finally the speaker cone itself needs to have a clear path to push sound energy into the room, if this path is blocked by furniture (some people like to hide them under tables) then it may make that furniture vibrate.
