Anyone familar with this Technics driver of at Apex Jr?

[Hybrid fourdoor]

Anyone know what this driver is all about?

Technics EAS32PL02S
3 way speakers
D : 150.24mm (6")
Re : 6.38 ohms
Fs : 63.56 Hz
Qms : 11.56
Qes : 0.88
Qts : 0.83
Vas : 8.82l
L@1K : .88mH

$175.00 per pair, sold only in pairs.

An externally hosted image should be here but it was not working when we last tested it.

Looks like something trying to make the best of point source.
And I take it all those rings (textured thin ones) are surrounds, seperating the various drivers. Anyways they look super intriging and was wondering if their anygood.

With a QTS of 0.83, I don't even want to imagine a box
for it 😱

Thats the good part, no box necessary😉
I contacted Steve(?) at Apex about these for further info but what is on the website is it as far as info. If they were cheaper I would have bought a pair to experiment with.
Some of those unusual japanese drivers make some real good sound. I remember about 10 - 12 years ago some flat, square Sony drivers that were real nice.

Dude... Qms of 11.56 and Qes of 0.88.... doesn't that mean, like, WAY low efficiency?

 

[phase_accurate]

fs is quite high with 63 Hz and because efficiency is only proportional to 1/Qes it is also proportional to fs^3 which will compensate for this and also for the Vas related part of efficiency.

BTW: the low VAS (if this is really true) makes an "infinite" box quite small.

There is one detail I don't like about this driver: Foam suspensions.
