assistance requested: dahlquist DQ-8 woofer replacement

Hello all and thanks in advance for your experience.

I bought a used pair of DQ-8s that are turning into quite the repair & upgrade saga.

I’m powering them bi-amped with a Yamaha RX V1600. Most recently while comparing some test tone and sweeps, I’ve noticed significant distortion in the left woofer.

The price of each woofer replacement from Dahlquist is over $160 plus shipping from Denmark (I know this is just peanuts to an average audiophile) and that seems quite high to me.
I am feeling uncertain whether I should:

- buy the factory replacements from dahlquist (plural -I can’t see a reason to not replace both at the same time)

-get the woofers rebuilt locally (this could take forever during the great plague of 2020 and cost as much as replacement)

-take a moment and get some guidance to upgrade them with something reasonable cost/domestic shipping like a Morel, SEAS, Tang-Band(?) can any of you suggest raw frame drivers that would bring new life back to these old mid-range boxes?


If I get a different brand replacement will this make my crossover “wrong”? (I already had to replace the Vifa tweeters with suggested contemporary Peerless tweeters).

-junior stereophile learning as I go...

Contact speaker rebuilders and inquire. Millersound in PA is great but a country away

Contact Madisound for replacements

Evaluate these options and the Regnar fix, decide and move forward.
 
I was not aware that Madisound has a friendly speaker expert *sitting by the phone*
you sir, have me going in the right direction.
 
What is the problem with the woofer. Is it possibly the surrounds are shot? Maybe a pic could help us.
 
the (to my limited experience) sound of voice coil distortion became apparent in one woofer in the low mid band in a series of channel specific tone sweeps. The "bass localization" test tones from audio check.net specifically.
visually they look clean and orderly..will follow up with a photo.
