Greetings,
I'm currently converting a few 70-80's vintage RtR 280s to sub only duty. And I'm in need of a few 10" 2300 8ohm woofers and or repair cones, spiders, and voice coils. Apparently post secondary market support for these never really occurred, as the pro's don't have any data in their files. And from what I gather most were produced by RtR, with a small production run produced by Rola. I've scoured the available 1 1/2" voice coils and haven't located any that have the same winding height. Same for the spiders which were apparently doped differently for less stiffness for less resistance. Lastly, the cones are also special consisting of a composite of purple paper pulp with an added assortment of different fiber threads.
So if anyone happens to have any of these around collecting dust please get in touch. Plus if your into winding voice coils also get in touch as I may have to produce a few.
Thanks,
DD

You want to repair the old drivers just to make sub-woofers out of the speakers????
If this is some sort of nostalgic restoration, I could understand. But if you just want to get the speakers working to make some bass, I would set aside the main drivers and replace with some current 10".
I just finished "restoring" some old rtr 600d speakers. I imagine you'll run into the same issues I did. 🙂

Hi Dave,
Thanks for the reply. Sorry to hear of your issues with the 600d whatever they may have been. The models are apples and oranges at least on the bottom end. Neither are suitable by modern standards for full range reproduction. Hense in this case the sub conversion..
It appears your assuming that these drivers are "unworthy" by modern standards. Frankly, I see no need in entertaining debate over this. As either it's your cup of tea or perhaps not. Either of which is okay. Currently your free to believe and assume whatever you wish. Enjoy it while you still can.
It's all good,
DD

Who said anything about the drivers being "unworthy"??? On the contrary, the woofer drivers utilized by rtr at the time were mostly from CTS and high quality. The drivers in the rtr 600d were not beyond hope and I simply replaced the surrounds and they sound fine again.
I used to sell these speakers many years ago (and have been inside a bunch of them), so am well familiar with any apples/oranges comparisons.
My comment simply meant that if you're going much beyond surround replacement, it's going to get quite involved with probably little chance of finding suitable replacement parts. But, you're obviously free to do whatever you like.
Next time leave the snark on the sidelines.
Cheers,
Dave.
