Econowave? That's a bit of a backward comparison, don't you think? That JBL waveguide design with a JBL compression driver, and a 15" JBL woofer is more like JRX115 than any econowave, or the M2.

The Selenium was used because it's cheap. I'd add CDX1-1746 to your list of better options for ~2x the price.

Oh c'mon Bill. You and I both know output trumps sensitivity.

agreed
2k tweeter is applicable for mini [poor's]M2 (similar to mini tannoy autograph) with 8" woofer

It looks like JBL has come out with another driver in this series. The JBL 2408H-2. Here's some things I notice about it:

1) The price has been reduced further. The BMS 4540 was made in Germany, cost something like $150. The JBL 2408H was made in the USA. The JBL 2408H-1 is made in Mexico, sells for about $120. The JBL 2408H-2 sells for just $85.
2) It's hard to tell from the pics, but it appears to be about a third smaller than the 2408H-1.

An externally hosted image should be here but it no longer works. Please upload images instead of linking to them to prevent this.

Here's a 2408H disassembled. I can't find any pics of the 2408H-2 that I can link to (yet.) Stumbled across it while looking for a 2408H-1 to go with the one I already have.

Interesting that the sellers of the 2408H-2 indicate no replacement diaphragms are available.
