Name is "Konaki" and they are essentially a DD 9500 copy as far as parameters and motor design.
I just measured the T/S on the 15" D1 Konaki here today... a customer of mine just got four of them and pulled 147.8 dB in a *terrible* box for the meter that he threw together and one SAZ-3000D on stock Ford Expedition electrical. I'm going to help him make a better box and he will be picking up a second amp... so it should do well by then. But, that is not the point of the post.
Anyhow:
Re = 1.88 ohms
Fs = 41.42 Hz
Qes = 0.446
Qms = 9.35
Qts = 0.425
Le = 2.80 mH
VAS = 26.6 L
BL = 21.33 N/A
Cms = 35.5 um/N
Mms = 414 grams
So... this is a copper coil just like DD, uses the DD G basket, judging by Mms and visual inspection the coil is the exact height as a DD.
The BL^2 / RE is higher than the DD 9510E that I measured -- 198 for the DD and 242 for this woofer.
The Cms is actually lower than the DD 9510E that I measured, quite a LOT stiffer. This design uses a spider spacer rather than just stacking them up.
The pole has the same cross-drills as the DD 9500 motor... I can't cut it down to see if it has the cooling channels in the pole. It does NOT have the top plate channels, though... but otherwise, so far, appears to be a DD 9500 replica done fairly well.
The bad... build quality isn't up to DD standards. He popped off the spider landings and had to glue them back down. The good... would probably work quite well after you broke the spider landing off the first time and re-glued it with epoxy (which he did and they are fine now).
I think they literally sent a 9500 to China and said "copy this speaker"
----
... and no, I'm not suggesting you sell your DDs and buy these. I just found it pretty interesting that this company just plain copied DD so blatantly. Thought I'd share.
Discovered some more QC issues with another one, the bottom spider broke @ the triple joint. It still plays as the top spider is still attached but does make a nasty popping noise at high excursion.
Consider these poorly assembled DDs *laughs*
