Default Infinity QLS1 Woofer replacement advice needed

Would like to replace the 12" woofers in these and wondered if anyone knew
of a decent quality similar spec DVC woofer for them.

Also could use one of the domed midranges too if you know a match.

Thanks

Try writing as Harman is now the supplier of Infinity
parts. I know that my Kappa 8s are about 15 years old and when I needed a new
pair of woofers they had them in stock. Not all parts are carried by them but
they should be able to tell you who or where you can get repairs or spares for
your speaker components.

I owned a pair of QLS's for about 4 years in the late 80's.
One of the things that made the QLS unique was that it used a
"Watkins woofer". My understanding is that the Watkins woofer
had 2 voice coils, each with a different impedance. To extend
the bass response, a special crossover shifted frequencies
near the resonance point of the first coil over to the second
coil, which had a different impedance & lower resonance frequency.

Every dual voice coil woofer I've seen for sale in the last 15
years has had 2 coils with the SAME impedance. I haven't looked
around, but it may be hard (if not impossible) to find a new
woofer with the special impedance specs of the Watkins woofer
used in the QLS. I know that's not very helpful, but I'm
just saying an off_the_shelf woofer might not make a suitable
replacement. It would be better to either repair the one
you have, or try to find an exact replacement.
