Size of Midrange Drivers


Why, in this day of super materials, do designers still use
mini midrange drivers?
Can we expect realistic dynamics from a five inch speaker?
My former Audio Artistry Dvorak's used dual eight-inch
midranges (D'Appolito config, paper cone) and sounded fine.
I'm thinking great dynamics = lots of air moved quickly.
I'd like to hear dual eight inch diamond coated berilium with 1000 watts behind them!
I think when we're at the point where the wave launch gives you a skin peel,
we'll be close to proper dynamics.

I think the planar route is the way to go.
I'll have to wait for Martin-Logan to vapor deposit
diamond onto their panels so they can play at higher SPLs
without breaking up.

The Martin-Logan Summit X's are rated 91 dB/2.83 volts/meter, and can handle 200-600WPC. The CLX's; 90dB/2.83 volts/meter, and can handle 20-450WPC. Either should be capable of satisfying most SPL cravings, quite well. I've always said, "size matters!"
And Magneplanar X.7 series--1,7, 3.7(i), and 20.7--have sort of blown past the stereotypycal limitations of Maggie speakers. My 1.7s are dynamic, coherent, and can play loud and clean on 100 wpc (200 into thei 4 ohms) in a vaulted ceiling open architecture living room. The X.7 series are the first Maggies not to have been designed by founder Jim WIney. They were designed by his son, who apparently successfully addressed the chronic complaints about the previous iterations.
