Just imagining said 'fantastically powerful magnet' and a glued cardboard cone...
Nope, by brain won't allow it.

Wasn't here long time. It is sad to see the content and responses didn't change and mature much. It seems that scientists are not sciencing much anymore. Frequency response is now about irrelevant. The constant power response with displacement volume, large signal behavior are! This thing will play, and it will play loud deep. Not exactly recommended for 10Hz, but 18-30Hz well within the need of use. It is just that the amplifier needs enough voltage swing to feed into the impedance peak (or overall rised impedance curve).
The OP had good first contact response, especially when people brought up just negative opinions, not real world facts. Ooof.

Been distracted with this 10 inch tower and hifi cabinet build. Yet to house the Beyma tweeters you see on top. Construction is 32mm thick black american walnut with medieval stud bolts. Hifi door in the middle is hand carved from a solid 90 x 56 x 14 block of teakwood. Grilles are teakwood also (removed for listening) 550 lbs total weight.
I will sort the 24 precision devices out soon i promise.

Drivers used
Beyma cp21 F
Eighteen sound 10MB600 or Eminence KappaLite 3010LF
when i have the eighteen sound in i xover at 4.6k, for the kappalite, 3.9k
It's a dirty n loud system for hard dance and D&B
Cabinet vol is close to 6cuft, so rather large for most 10 inchers. Both these drivers have good strong motors though, never hit the coil on the back plate.


Cabinets braced externally...

Loving the Medieval Keep look. Just the style for playing Gregorian chant techno... 😉
Yeh
My new house was built in 1537.
Oak beams, panelling, floors everywhere, in order for the missus to accept huge cabinets it's got to be in keeping with the house. The PD 24 will be getting the medieval treatment too.
