I am not sure if it worth to paint them. I got about a dozen of those original speakers and most of them looking like brand new, however not a single one of them woks right. 44 years old paper cones warped a bit. Coils rubbing against the magnet is a very common thing. Yes, it is possible to fix it. I prefer the easy way though. Replace them with something similar looking. Quiet few available on Amazon or Ebay. I did checked a few and it's Alpine 1751 and Rockford Fosgate Prime and my favorite Pioneer A-series TS-A1601C.
Replacing or restoring Sharp GF-777 speakers?
- Thread starter Rando11
- Start date
Thanks for the warning about original GF-777 speakers possibly having warped cones or voice coil rubbing.
My first plan is still to keep the original speakers if they work properly, and only do a very light cosmetic restoration. I would keep the original speakers in any case.
It was a bit of a surprise to me that the original loudspeakers were black and not creamy colored! If someone else in addition to the user on page 1 can verify this, it would be great. But having looked at the backside of the speakers, they are indeed black. I have attached a picture of an old brochure and it sure looks like the original color was indeed black.
I finally managed to remove the loudspeakers from the housing. Have a look at the attached picture. It seems that the surrounds of two speakers have lost their black color, so even the surrounds should then be painted black.
However, as a backup plan, I would like to ask about replacement speaker options. If I ever need to replace them, I would prefer speakers that look as close to original as possible behind the GF-777 grilles. I am not looking for modern-looking flashy car speakers with bright logos, colored cones, extra tweeters, chrome bridges etc.
Do you have any specific recommendations for replacement speakers that fit the GF-777 well and look reasonably original once installed?
Important points for me would be:
Thanks!

Important points for me would be:
- correct physical fit / mounting depth
- correct impedance and sensitivity for the GF-777
- no major modifications to the cabinet
- original-looking black/silver cones
- good sound, but not at the cost of making the unit look obviously modified
Thanks!
Up! These kinds on Pioneer loudspeakers would look quite good and close to originals without the grill IMO: https://sbrprosound.co.za/product/pioneer-ts-g160c
Maybe a silver cap could be bought and installed on top for the speakers in the middle? I wonder how to connections should be like, since there are also the tweeter horns in play and the speakers in the left and right edge have capacitors installed. I would need specific info on how to make the connections.
My plan now is to take my unit to a repair shop, since the cassette deck needs cleaning and belts replaced and I will ask them to listen the restored original speakers, how they sound and if they find that they are not good anymore, I will ask them to suggest alternatives. But I am afraid they will say no to any replacement car speakers and just tell that pimping an old system is not a service that they provide...
Picture of the caps inside the 777 loudspeakers attached. Anyone know the type number for the loudspeaker on the right in picture? I cannot figure it out.

Yes lighty dusting them. Just taking time and not overthinking it. Done it many times,with no noticable effect on sound.

I spray painted n old Yorx box's speakers just to get my feet wet when it came to painting speakers. I chose the York because I was willing to sacrifice the speakers should anything go bad like drips or unequal application. Like others have stated, experiment on some cardboard, spraying from about 30cm's away and continue to spray beyond both edges as you sweep across.
I've found going through household cleansers (even shaving cream or air fresheners!) containers have a wide variety of cap sizes that'll work well as dust cap covers.
Take your time and remember...less is more. Don't try and cover it on the first pass. Multiple light coats yield a better result.
Good Luck!

I've managed to hire a professional painter to do the job.
What about the replacement speakers in case I would have to go that route in case where the 40-year old speakers might not be that good anymore?
I was looking at 4 x Pioneer TS-G160C as they look quite good, but as I do not understand anything about electronics, I would need info on how to connect them (should I remove the capacitors connected between the speaker and tweeter?) - or let alone, can I use four of them in the first place...

The speakers look nice. I assume they won't need replacing.
Mine has the original speakers and the sound is good.
