New OB build - RA CG12 Super

[fringy75]

Hi all.

I salvaged 2 Richard Allan CG12 Supers from the local refuse station, and once I am sure that they are okay to use, I would like to build an OB system with these as the bass units.

I have the published tech details as supplied by ZeroD.

FS 32
Qms 2.55
Qes 0.11
Qt 0.105
Vas 7.63 cu Ft
No 6.3%
Cms (M/N) 7.83
Mms (gms) 31.6
BI (wb/m) 18.6

Can anyone advise if this driver would be suitable? And if so, how can I work out what tweeter would work, along with crossover component.

Sorry for so many questions, but a complete nubie when it comes to OB.

Thanks in advance.

This is a nice driver for sure. But it is as far from OB use as it gets. Qts is incredibly low. You will need massive EQ to get the response linear to 30-40 Hz. And the surround doesn't promise large excursion capability.

A large bass horn looks like a much better home for this sort of driver.

Thanks Rudolf, I appreciate your feedback. I did wonder when looking at the driver, so will rethink my plans.
