Not saying what the driver is but here are the specs. Any thoughts? ;-)
FS - 37.9 QES - 0.335 QTS - 0.330 BL - 21.879 EBP - 113.13 LE - 2.29 BL and QTS look good but EBP and LE are shite. Whats most important for the MT? |

2x the EBP is the mass corner, or 226hz in this case.
This driver will have trouble pushing air into the throat of a horn much above its mass corner (as any driver will).
This can be seen if you load it into Hornresp.
The EBP on the 12PE32 is 268 Hz, so the mass corner is 536hz. With an optimized thoat it can reach 1Khz and only be 5dB down (on a constant coverage horn).

Thanks for that..
I've been after the input paramaters for the MT so i can make my own comparisons so this is a great help. Actually i use XT8 horns over a pair of TDA version MTs at the moment so these don't look so bad as i can cross them over down to 350Hz (ish). I built them a few years ago and not been able to afford to load the MTs yet. These are the specs for The Box drivers which, not ideal maybe, are only 50 euros each. :-) |

The "W" version is a very heavy coned 4" VC subbass driver. It will sound absolutely horrible in a MT122, or any mid/top at all!! |

But if they are only playing between around 150 to 300 or 400 hz do i need such a high EBP?
