10\" horn drivers

Could anyone please recommend a 10" driver for a horn? I'm looking to x-over at 500 Hz so extended high frequency response isn't important, but I am looking to use it down to 70Hz, so it must be capable of handling low frequency equalisation. (this is for hi-fi use)

Maybe having a look at 18sound m600 or mb600 i think they're called.

I've looked at the following drivers, how can I tell if I can safely use low frequency equalisation to extend the low frequency response?
JBL 2012h (300w fs61Hz xmax5mm 100dB/w)
18Sound 10M600 (400w fs70Hz xmax4mm 102dB/w)
B&C 10MD26 (350w fs76Hz xmax1.5mm 100dB/w)
Precision Devices PDN.10MH25 (300w fs79Hz xmax2.6mm 99dB/w)
Beyma 10MI100 (350w fs89Hz xmax2mm 101dB/w)
EV DL10X (300w fs60Hz xmax4.1mm 97dB/w)
Faital Pro W10N8-700 (700w fs56Hz xmax9mm 96dB/w)
RCF L10/L750YK (</font>350w fs68Hz xmax2.5mm 100dB/w)
Volt M2500 (200w fs47Hz xmax0.44mm 99dB/w)

I would personally try simulating it, looking at the driver excursion, and thinking about that. Where driver excursion is low, you can add a bit of EQ. How low are you trying to reach?

The other option would be to port the rear chamber.

I can only speak for the B and C 10MD26. I used it to good effect in my MX350's Which are horns. Size, area, etc. of the horn will have it's affect on any speaker. All volt 10's are good.
