Yes I had seen that, but I'm looking to keeping my purchasing state-side. The international shipping would cut into the bare driver cost ceiling I had set.

Yeah, I looked into importing some Oberton drivers. Shipping was just too much.

Are the RCF's out of reach? LaVoce WAN103.01 might be interesting as well.

None of the RCF's really pique'd my interest, and the LaVoce looks interesting, but as was suggested to me by a very astute acquaintance of mine: be wary of drivers with a peaking response in the 2 or 3kHz range, as they usually stem from distortion, either 2nd or 3rd order harmonic @ 1kHz (one shows up as a peak near 2kHz, and the other would be a peak near 3kHz), which you will see when measuring harmonic distortion. And he was right, the B&C which has a peak near 3kHz had a 3rd order harmonic peak at 1kHz which you can see fro the distortion measurement. The LaVoce mfg spec sheet shows this same characteristic, so I may or may not be incorrectly assuming what I have found with the B&C driver.

I had not heard of Oberton drivers. Some of their 10's have nice specs, including double demodulation rings. If they had a distributor/dealer state-side I would probably buy a pair.

Nice pictures and good measurements. But still a ridiculous mechanism for moving air accurately and fast. Some day people will laugh at us the way we laugh at open-back Philco radios from 80 years ago.

That little driver with the 9 gram ceramic dome assembly makes a lot more sense... at least until graphene air-movers get here*.

Look to the future.

Note 18Sound classifies 10NDA610 as a midrange rather than midbass. How high are you planning to xo these?
I found a 10G40 at a good price, so I should have one soon.
