High sens 4'' driver

Gowa

I'm looking for a 4'' driver with as high sensitivity as possible. Know any?

Looks like even pro audio stuff is limited to about 90-91db.

Best I can do is PRV 5MR-450NDY. The 4MR60 is about 91dB.

That TC10 modeled well in a Synergy horn along with the Visaton R10S

That TC10FG would make a really nice hybrid OB mid on a narrow baffle (rear mounted of course).  I probably think that because that's what I'm into right now

I've been wanting to use them in an MMTMMWW for a while.  With 4 per side, you'd be at 99dB @ 2.83V/1m.  Of course it's only moved from 9th to 7th on my project list over the last 4 years.

The Faitalpro 4fe35 is 91db 1w/1m. might be worth checking out.

Yeah, looked at that one a lot. 2 of them in an MTM "top" get you 97 dB raw, 95 dB or so after BSC.
Very reasonably priced, also.
