Need Help With Replacing A Speaker.
- Thread starter ClintUtz

In general a speaker reconing is much less expensive than a new speaker. That said, if it blew because it was a crappy speaker or loaded incorrectly by the cabinet, it will just blow again. What happened to it?
Im not really sure how long its been blown or how. Its pretty old i would say at least early 80s. It was given to me and it is a hand made cab. I really like the cab and would like to get a new speaker and it also doesnt have a tweeter or horn but it does have about a foot long about 2 inche wide slot to move air. Would getting a tweeter or horn help.I think i would like to find a good all around woofer if anyone knows or has any brands they think would be suitable please let me know. Thanks
I would say Eminence. But as I said before, you need to reverse engineer the cab. Post a thread here with the dimensions and pics and someone will probably help you out. There are more than a few guys around here who know about this stuff.
Sounds like you need the surround replaced. You can buy these online for around $20. If the voice-coil is good, I would recommend fixing it. The surround repair kits usually include the adhesive, so its a very easy repair.
Tech-tip: place the driver on an old phono turntable or a lazy-susan when applying the adhesive. (you hold the glue tube stationary while slowly turning the driver(on the turntable) as you apply the glue)
If whoever built the cab just hammered, screwed, or glued some wood together to make it, it could be that the speaker is not getting the air support behind the cone it needs to keep it from tearing itself up at high volumes.
heres the dimensions of the cab if anyone knows how to reverse engineer cabs it would be greatly appreciated. The inside from top to bottom is 29 inches same from left to right 29 inches. from the back to the front board is 11 and 1/3 inches but theres foam on the back of the inside adn from the foam to the front board is 10 inches.I cant figure out how to upload pictures can some one tell me how im a little slow at this stuff.
It should be pretty easy to figure out if it's foam rot from an old speaker of that vintage: If the rest of the foam around the edges is fragile and crumbly, it's foam rot. If not, it's more likely to be speaker abuse or cab dimension fatality.
But foam rot seems to be less common--I haven't seen it in years. Speakers of that generation seem to be either all shitcanned or all repaired by now.

The internal volume is about 5.5 cubic feet before subtracting for speaker and port volume.
We also need to be able to figure out the approximate port tuning frequency.
Near as you can measure it, what are the exact dimensions of that slot - width, height, and depth? And, where on the cab is it located?
Is the tear all the way around the edge of the cone, or just in one area? If the latter, where is that area in relation to the slot port?
