Tell us more!
Would love to build a pair if they are as great as "they" say they are...
I think the most interesting part of it is the tweeters - the very same that SpirosZ linked to.
They are small enough in size to minimize combing effects by allowing closer placement to each other and the woofers. (..probably all series connected - with a net an average spl slightly higher than there reference - say an honest 96.5 db for a nice easy impedance).
There is also likely enough gain from the woofers to provide baffle step compensation.
The only real problem IMO is the use of 10" drivers - which are probably also custom.. in a 2-way design.
-it's a bad idea for the same sort of reasons I previously mentioned about the Lore.
A much *better* choice would be a 3-way (2.5 actually) with a smaller mid driver.
ie. 3 X SB tweeters, a B&C 6MD38-8 mid, and THEN the 10" drivers. Crossover the 10" at a point where baffle-step occurs (so you don't need baffle step compensation).
-yes, more expensive because of the mid.. BUT almost certainly MUCH better performance.
A pair of eminence 10B's in a 7.5 cubic foot cabinet with a tuning freq. in the mid 20's works out well when factoring in the gain of the drivers parallel connected to 8 ohms and pressure losses from the baffle. Might not need much more than a large iron-core inductor with the right size baffle for good integration with the midrange.
