First, would the JBL 2123 drop in and behave the same as the ALpha re: naturally rolling off w/o coil or cap? Of course the Fs is higher: 85Hz but no matter.
According to the link below the JBL 2123J is "ruler flat from 150 to 5000 Hz".
That leads to the second thought of having a 4Pi Pro box with 2226J, a small sealed box on top housing the 2123J and then, for all JBL system the 2404 or 2402 bullet on top.
The bullets are hards to find except the 2402 for almost $300 each. THAT leads to the third thought which is 'would the Vifa DX25 serve instead of the JBL Bullet? I refer of course to the drop in sensitivity from the 2123J about 100dB and the Vifa 94. Would attenuating the Vifa be much of a sacrifice vis a vis the very high price of the more efficient JBL Bullets?
