New member - Dahlquist DQ10 questions


Hello gentle people,

im a retired electronics engineer so I now have time to do some repair projects I've been wanting to do. 
I've wanted to get back into listening to my stereo setup and be able to play vinyl again so I resurrected a pioneer pl 50 table and then got to looking at my DQ10's thinking I'd refoam the woofers, check the crossovers, etc. I've owned the dq10's for over 25 years and never did a thing to them but when I got them apart, I found the woofer surrounds to be in great shape, which I thought was really weird. The guy I bought them from mirrored them and I'm wondering if he then coated the woofer foams and that's why they're in such good condition.
I did find one of the 5" mids has a approx 1/4" tear in the rubber surround. It plays ok but I'm thinking the surrounds on both mids should be replaced. 
I've been doing a lot of reading but see no replacements for rubber surrounds for these.
Anyone know of a source?
Also, I'm driving these with a (about to be recapped) quad 405-2, that is driven by a Mac C27. 
Im thinking even after a recap, the quad may not be up to the task. Thoughts?

Thanks very much

If you happen to want to make your own stands, below are some dimensions for making them obtained from Regnar, years ago. I finally retired my DQ10’s this past year after 40 years of faithful service, passing them on to a neighbor.

DQ-10 Stand Dimensions

Top platform: 15" W x 7.5" D
Back Lip attached to top platform: 15 W x 1.5" H
Column posts (in between top platform & Bottom Base): 7" H
Bottom Base: 22" W x 11.5" D
Posts are 60mm square

Made contact with Bill LeGall. I'll send the mid speakers out this week. 
What are your thoughts on my woofers being in great shape after all these years? As I mentioned, I'm assuming they were coated years ago and that preserved them. Would you leave them as is?

I hope this doesn't sound ignorant but, when the DQ10's are mirrored, which one is considered left or right?

thanks for everyone's time.
