Dahlquist DQ-10 - did they use Advent woofers?

As J. Peter Moncrieff stated: "No midrange driver, no midrange".

I had a couple of Advents when they first came out. As I remember, one of its features was that the woofer was a 10" cone built on a standard 12" driver frame, so as to leave more room for a compliant suspension. A clever low cost production strategy.

I thought that the Advents sounded good, particularly as a "stacked" pair, which enjoyed a brief period of high end hype. However, I found the midrange, particularly vocals, to be lacking in comparison with the similar sized KLH5 and the KLH 12 (same drivers) which were three-way designs.

Yes, it's a Advent woofer. These guys will have everything you'll need, http://www.regnar.com/

it is the same woofer used in the Large Advent that Kloss designed. As above, it is probably the surround. However, search around and you may be able to find a replacement woofer. I've seen a few.

I don't know who actually manufactured the woofer but yes, it is the same as the large Advent woofer. DQ-10s below serial number 400 used a 12" CTS woofer. BTW, kits to replace your foam surrounds are available on ebay and it's a relatively easy project.
