JCP1990S4

I just brought all my speakers in to be rebuilt.

I brought them to Speaker Works in Orange, Calfornia.

They will be able to rebuild all but the two woofers. They are installing two (2) Kenwood speakers inside the original housing so that I can use the original covers.

Will be done next week, can't wait.

I will let you know how it went next week.

Thanks for your suggestions to have them rebuilt!

Sounds interesting...How much $$? compared to new speakers.

The rebuilts are costing $35.00 each.

The other two (woofers) are costing the cost of the speakers and $5.00 each to mount and install them in the old housing.

I think it would cost more for new and I get to keep the original blaupunkt speakers!

You did the right thing there.

Jeff please definitely keep us posted on the quality of the repair. Specifically is the material they use the same or an improvement over stock? Are upgrades available? Do they offer mail order services where we return our existing speakers and have them repaired?

+1, I doubt there's anyone by me locally that offers that type of service, so I would be interested as well.

Did they say why they can't rebuild the woofers? Usually just the foam surrounds are torn/deteriorated and you can replace the surrounds. You can even get them online for DIY repair. I've done it. I even bought some such damaged woofers from 928 Intl and did this with good results.

I'd be interested in seeing how they fit the Kenwoods to the stock housing, how they handle the crossover hardware, and what you think of the sound. The stock woofers were not super high quality, but they were designed to work in that area, providing reasonable bass response despite the large open-air cavity behind them. Nearly all replacement speakers require a closed cavity, although there are some designed for free-air like this area of the car. So, usually after the rears are replaced with aftermarket speakers, there is less bass and a sub needs to be added.

Let us know how this comes out!

Is Speakerworks doing the rebuild or just farming it out?

I'm thinking this place in Garden Grove does the work.

If by rebuilding your speakers you mean they are replacing the outer foam ring, it is a super easy DIY and extremely cheap. I replaced the foam on the woofers in my GTS and they sound great! If you need details I will find the place where I bought mine. There is also a thread with a great step by step of the process.

Put some speaker foam baffles behind the 6" speakers if you want to close off the back from the 3/4 panel cavity. Don't think that's cavity is anywhere's close to being sealed.

Speaker Baffle on Crutchfield
Think I've seen the foam baffles on Ebay as well.




I've got the slim 6.5" ones for the B-pillar speakers and slim 4" for the doors.
Don't have audiophile ears to hear if it made that much of a difference.
But I know the 4" door baffles keep the water off the back of the speakers.

Do the foam baffles affect sound quality or do they just serve as protection from the elements?

ew928

Baffles isolate the back of the woofer/mid cone from the front. So the soundwaves will not cancel each other out as much. (speaker cone moves forward to make sound, back of speaker cone moves away from the air behind speaker to generate neg. pressure wave. Good to keep them apart)
It's not a perfect seal like a nice speaker enclosure. But better (cheap too) than nothing.
And few doors/ 3/4 panels are decently sealed.

Ernest did you use the foam enclosures behind your lower/rear woofers also? If yes did you note any reduction in speaker resonating?

Some good info on this post!

I have a subwoofer in the car and didn't do an A/B test of with and without baffle.
Bit hard for me to tell if the baffles made a big enough difference to the sound.
But the price was pretty low and very easy to install. (I should have put baffle only on one side of the car's speakers and disconnect the sub to get a clearer indication of sound changes)

Just trim the foam baffle around the speaker. Cut tiny slot at base of the baffle to thread the speaker wire through them. Re-install. The machine screws should self-thread through the foam on re-installation.
Plus is that the baffle forms a nice seal around the speaker to quell any noise coming through around the speaker.
