A few questions...

[theman4455]

I know this will sound crazy, but I have a pair of old Cerwin-Vega D-3s and the subs dry rotted. Well... I got a stupid idea to make headphones with the crossovers. I figure (I'm bored as hell and I'm just doing this for fun to let you know) "I've got an old pair of computer speakers, I'll use it as an amp, go into the crossovers, use a pair of over the ear (the ones that cover and have depth till you get to the speaker) headphones in place of the subs, and two pairs of earbuds for the midrange and tweeter." Like I said, bad idea... it's more for fun than anything...

So... my question is... are the impedance/resistance differences gonna be a problem? The crossovers are 8 ohms and I think a majourity of headphones and that are only 2 ohms... I don't know how ohms work, so... yeah.

Thanks for any help, and I'm sorry it's such a moronic idea...

Sorry but,
I think you've answered your own question.
The impedance mismatch is a problem.
The crossovers are made to work with the enclosure, and drivers in the Cerwin's.
Below is a link to help explain:

It's great that you want to experiment; though I'd learn a little more about the subject first.

The beauty of headphones is that they don't need a crossover. You idea is DOA anyway.

If you want a project refoam your speakers. It is quite straight forward and you will lean a lot.

Alright, I'm new to it so... yeah. I'm too lazy (comes from being young) to look stuff up really thoroughly...

And as for refoaming, someone replaced the foam (after peeling the rest away) with some cloth (before I knew about refoaming...)... I guess I could replace the subs completely? (I know I have to use 8 ohm now at least. ^.^)

Here is a link to a 'how to' for re-foaming surrounds.

It's an example, so if you're interested, Google 're-foaming speaker surrounds' to look for kits.
Also I'll bet our friend TLS can give you links to some good ones.

Also, I wouldn't replace the entire bass driver. The reason is the same as in post # two.
The enclosure, crossovers, and drivers are made to work with each other.
A replacement would have to be an exact match in every way. Chances of finding it are slim to none; especially when you can re-foam them for between $15 and $20.

A buddy of mine who says he has no real mechanical skills was able to refoam his speakers himself, so I don't think it should be all that difficult.

It really isn't that tough to do. You should follow instructions and you will be fine. Make sure you strip off all the glue and old foam as leaving any will cause the speaker not to bond properly....good luck
