Talking Bohlender Graebner RD75 with Acoustic Elegance Dipole15 Open baffle Project

Below is the design of my open baffle speaker. It uses 4 AE Dipole 15 inch woofers for low frequency, Planar transducers for the mids, and 2 Aurum Cantus striction tweeters for the high frequency.
Note: I do not have money to build these right now. This is just for fun.
What do you think? Is it overkill?

Bg planar = $753.50 x 2. (4 total for pair)
Aurum Cantus AST2560 Aero Striction Tweeter = $169.49 x 2. (4 total for pair)
AE dipole15 = $314 x 4. (8 total for pair)
Total cost for pair of speakers minus cost of crossover and baffle = $6203.96!!!!
HOLY SCHNIKES!!!!
The baffle will be sand filled and the crossover will use high-end silver oil caps and copper foil inductors plus high gauge silver wire throughout.

Or would you just rather buy Magnepan 3.7's and get a pair of subwoofers?

as it is now, with two horizontal tweeters/mids is complete disaster...
no matter how much drivers cost, it would sound worse than bose

drop one tweeter and mid per side
and if you like expensive drivers, use RAAL tweeter

In HELL you'll got plenty of time to make that perfect speaker and eternity to listen to it.
But one at a time.
'cos in HELL stereo signal has little delay between channels...
generally one month

If you get the woofers off the same panel you might really have something there.

And you don't need or want the tweeter either.
