Not sure yet Cal, still trying to wrap up the Jbox build had a change of plans from the amp/dsp box to a plate amp set up. The cradle for the source (ipod/tablet) is at a design standstill but the cabinet has been finished in shellac&wax, can't seem to bring myself to using any other finish on walnut.
While pondering the cradle design i am building another monitor size pair on stands for the a10s in tigerwood with birdseye baffles on cherry stands this will give us a good comparison to the walnut monitors since it is about 50% denser then the walnut and the carcass stock is 15/16" thick with 1" thick baffles.
I'll send some pics when everything is done

These look like great little units Mark. I'm eager to get my hands on a pair. As Bob said, the slimmer frames would allow for more slender cabinets. I think these, combined with several of the popular, small form factor amps could make for some very enjoyable computer, or bedroom speakers.

One has to be careful how narrow one makes a box... too narrow and you start to hear objectionable reflections from off the inside sides. We ended up doing 3 millSize prototypes before we got the boxes wide enuff to avoid that -- the big bezel MAs fit fine on that baffle, i won't go slimmer.

Good point Dave. Certainly something to factor in when attempting to save desktop real-estate.

Mark already indicated in post 9 the Japanese domestic pricing for the CHN70 - $25-30 USD

all above unsanctioned wild a$$ed speculation of course
Hi,

I was quoted US $27, $79 and $135 for the 3 new drivers.

I'd heard much the same, but wasn't sure about its official status - I think final landed cost / exchange rates, etc will be part of the calculus - but close enough neighborhood for now, I guess

prices don't always go up

It will be interesting to compare this driver to the current gen CHR and CHP. $27 seems like a fair price, the CHR was $36 if I recall.

Well, as I postulated above, the metal cones are likely a more costly process than paper, but don't forget these are all projected USD pricing, so even if margins for local resellers permit, between currency exchange and shipping, landed cost to CDN DIYers could be higher.

All that said, I'm still more than eager to hear whether any of the new players approaches (or surpasses) the EL70.

Mark: would you happen to have the dimensions for diameter and net depth of magnets for this driver?

Hi,

Isn't this adequate?
