I purchased a pair of Realistic Mach 2's for $20 and I guess i turned the speakers up too loud and it started to make a weird buzzing sound? I touched the subwoofer area and i took a chunk out!

here are the pics...

Is this repairable? What would be the best/cheapest way to repair the speaker? Is it worth it?

For $20 speakers, you get what you pay for. It'll cost more for a repairman to look in it's general direction than to buy a new set.

I'm hoping to repair this myself if possible. Somehow fix the broken plastic/vinyl part...or put a new sub in the box?

buy a replacement driver. Just call the company up, tell them the model and they'll tell you the replacement.

there are foam repair kits out there, but not worth it IMHO. Duct tape will work if you're in a bind

-edit- if you touched the surround and it crumbled then they are suffering dry rot. Just replace the driver.

thank you spidey,

I just looked at the rest of the surrounding sub area and it appears to be in bad shape(dry rot). I also believe that this company might be out of business. What should I do?

I believe radio shack sold those. not using the exact driver will most likely yield bad results.

you could try to find out the parameters of the sub and try to find one really close.

It's not a subwoofer - that's a traditional 15" woofer.

Those were quite popular and I'm sure there's Thiele Small parameters floating around - somewhere. :p

Get a replacement driver with similar parameters and you'll be all set. If you're into some adventure you can start from scratch and get a suitable driver for the enclosure size and reflex tuning (easily changed) and build your own crossover.

I remember the Mach One's with the huge (for a house speaker) sectored midrange horn across the top. Those were great party speakers. :D

And if you want to keep the original driver you could go this route.

thanks for the help Ms. Dawn and Aliencraft...I spent $20 on these speakers so I don't want to spend tooooooooo much on replacing the 15" driver(s).

I'll have to look into replacing or refoaming!
