I am looking to design a small satellite system using the XT25SC90-04 tweeter and a small 3-4" mid-woofer in a small top cab and a 8" woofer mounted in a separate cab.
I want to run the sat module down to at least 300hz if not 200hz so the midrange driver needs to be pretty wide bandwith. Most of the 3-4" drivers i have found have a low sensitivity. But the Tang Band W4-930SF looks very interesting. wide and flat from below 200hz out past 3-4khz and 89db@1w where the XT25 is 91db so I wouldn't have to pad it much. most other small drivers are at 85db or less. and there isn't room to mount a 5" driver. a 3" would be an ideal size but a 4" will just fit.
The biggest problem is that this needs to mount in a very shallow but wide area so i cant use a mid driver with a giant magnet on the back. I might be able to raise the crossover point from the woofer to the mid but i want to try and keep as much up top as possible as the woofers will most likely be placed at knee level or otherwise not in a direct plane to the ear.
any other suggestions for a small midrange driver to mate to the XT25?

Will these suffice? SC50 and SC90 are not that different. Sat will go to about 114 Hz, so within your range. You won't really find a 3" with a 91dB sensitivity like you want.
Let me know if you have questions...

An externally hosted image should be here but it was not working when we last tested it.
