The top one in the second photo looks like an original DQ 10 woofer. It has a Masonite surround so it’s a 10 inch woofer in a 12 inch frame. ?This one should work well. If you’re not familiar with rebuilding speakers, I would send it to a professional and have them check it out. I use Simply Speakers in Florida. They’ve done a great job on 3 DQ 10 woofers that I had them refurb.?

I would not use the second 12 inch woofer in these speakers. It was the original design that Jon Dahlquist had for them, and some of the early speakers have a full 12 inch woofer, but for reasons mentioned in posts on this site, they switched to a 10 inch woofer in a 12 inch frame

Maybe someone here has one of the original advent woofers they’d be interested in selling? You could also search craigslist or other used speaker forums to see if you can find one.

Other folks here can chime in why, but I wouldn’t use the 12 inch woofer in the DQ 10s… It just won’t sound right.?

?I have this pair of DQ-10's I've been getting ready to restore/rebuild. One of the woofers has had the foam surround redone and they did what looks to me like a terrible job. The other one looks original as far as I can tell.

Online I found what was described as a fully rebuilt pair of DQ-10 woofers so I bought them thinking it would save me time and trouble. Now that I'm getting ready to start working on these things the woofers aren't the same. The frame and magnet are the same - but it's a full 12" woofer. Even though they are a direct fit I'm guessing these are a no-go for the DQ-10?

Here are some photos. Original on top, purchased on bottom:



Thoughts? Do I try them or is this just a complete no-go? I'm guessing they will sound very different than the originals. I looked online and have not been able to find a pair that looks the same - even on old advents.
