Pro driver 2-way horn

Has anyone used pro drivers in 2 channel stuff? I know that it is generally not used, but I like the really high sensitivity and if it's made for high SQ, wouldn't that translate into my living room? Here is the rough design I've been working on using B&C drivers and a 2nd order Butterworth crossed at 1.6kHz to achieve a 12db slope:
1" horn driver with 10" waveguide for the HF (FR: 1K-18K Hz, SPL: 108.5 dB)
10" LF driver (FR: 60-4000 Hz, SPL: 98.5 dB)
C1 = 8.8 uF
C2 = 8.8 uF
L1 = 1.13 mH
L2 = 1.13 mH
I will need a little attenuation though because of the 10db difference in the sensitivity, but a few resistors should take care of that.
R1 = 5.47 Ohms
R2 = 3.7 Ohms
As far as an enclosure, I haven't decided yet. I should probably give that woofer some room to breathe, at least a sq foot, but a big square box with two 10" spheres would be a little ugly IMO.
What do ya'll think?

Ya ya ya,
I had those in the back of my mind the whole time, and was hoping that my design wouldn't look exactly like them... -

Huh- they discontinued the waveguide. Oh, well, I'm sure you can find a replacement. You could also probably do a little better than those eminence drivers. Keep the Qts fairly high and make sure the driver in question breaks up someplace over 1khz.
Hell, for that matter you could always do a ribbon tweeter, if you wanted something different; you can find them w/; efficiency in the 100db+ range, too.
Obviously, I've been turning this one over. OB woofers, active digital crossover, high efficiency tweeter, pick up an old meridian 565 as a pre-pro to cut out any extra AD/DA conversions....Gallo Ref 3.1 : Bryston 4b SST : Musical fidelity CD Pre : VPI HW-19

With the parts I picked out, it would come to a little over $600 for the pair, drivers only. :eek: The wood wouldn't cost too much since it would most likely end up being an open baffle; and the crossover is relatively simple so that wouldn't cost too much either.
