MY JVC RC-M90 - PROJECT REFRESH

[Cpl-Chronic]

I still have to paint the chrome trim around the tweeters, now that the black is finished & the grills are painted. I'm working in the paint on the woofers.

The secret, when painting woofers is 2 thin coats. As soon as the first coat tacks, apply the finish coat, lightly. let the woofers dry 12-24 hours, depending on the type of paint, let them dry while resting with the cones facing up & sitting on the magnets. This allows the paint to flow evenly. Once it has mostly dried, but not yet 'hardened'(12-24hrs), install the speakers & put some good bass through them for the next 2-3 days & as much as possible. That way, while the paint does its final hardening the ribs of the surround won't get too stiff. This helps the speaker's suspension stay efficient. If the ribs of the surround harden or stiffen, bass response & SPL will suffer.

Once, you paint it, wait a day, then USE it or LOSE it.

Too bright a blue for my liking...it makes it look cheaper in my opinion. Hey though it's what you want that counts here.
I just thought that you might have gone a different accent rather than of the stock blue.... as some of your creations have been pretty wild.

En..Don't let the flash of the camera fool ya on the blue. The blue has a extremely dark undertone & the shift in color is pretty sweet in person. I'm just trying to show, from the photos how the chrome dustcap just floats inside that sea of blue. The grills pop against the grey monolithic styling of the M90.

Wait until I'm done....

Ah i see...get some daylight shots when you're done.

Best ever excuse to turn the bass knob all the way to its cold end!

ennn...Fantastic is really harsh on delicate finishes. Warm dish soap & water is best for grime & grease, etc. A soft bristle toothbrush is your best friend. It got to be SOFT bristle or your gonna scratch things up FAST!! Novus cleaner & polish works real well without the abrasive & corrosive crap you find in Fantastic. eek!

Cheers,

i meant as a cleaner in general. lol.. im always cleaning.

i agree... the blue/black fade is pretty sweet! if i catch the M70 in a certain light it changes..

Congratulations. That's one clean machine. Welcome to the M90 club.

Working in the woofers as we speak. Again, JVC has made an extremely LOUD & CLEAN sound from the M90. This is what the 777 should have been & I got it close on mine. Some songs, I love the JVC & with some I love tha PHAT AZZZ BAZZZ 777Z.

A short sound test after being rebuilt....

Don't forget to set it to 720p for full effect.

There's a couple of small rattles I have to sort out but overall it sounds amazing!!

Isn`t the paper of the speaker meant to "throw" the sound out , wouldn`t painting them cause it to throw less sound? Can`t really tell from the video? Thought of doing this to mine but worried it might change the sound..

The JVC woofers are already coated with a polymer of some sort so if you use light coats, you should be OK. There's a couple of tricks to make sure it comes out good.

Paint with the woofers facing up & resting on the magnets. Let tack dry for 12-24 hours depeinding on the paint dry time. Once it's dry, intstall & use for the next 2-3 days, with lots of bass to work the surrounds in. This keeps the paint from hardening the surround & limiting movement. The important part is letting it dry first but using them as it fully hardens. There is a slight loss in total SPL but it is a trade off for slightly deeper bass.

Thanks, going to try it on a lesser box first - those M90 woofers are tough to find !

Well, be careful what paint you use. Like I said, the JVC woofers are already coated with a type of plasticky substance so I didn't have to worry about absorbtion into the paper. Other woofers may not be as forgiving so really try it on a woofer you don't care about & see how it comes out first before doing it for a boom-box. Some members report good results with fabric paint you can buy at car detailing shops. I used my trademark blue for the JVC's but it is thick paint so I used light coats & as I said, used them to break 'em in after painting so the surrounds don't get stiff & limit the movement.

Good luck,
Cpl

There are fiber cloth with an adhesive back up near the rims of the cabinet case to stop vibration and rattling. If they are gone use black electric tape. Also use fasten loose wires together.
