Cabinet Idea for Hammond Rola AO 21055-2

Hello to all,

I have tested the Hammond Rola AO 21055-2 Speakers in an open baffle.

But the bass response is quite poor.

Does anybody had build a cabinet for this speaker?

Closed cabinet, bass reflex, front loaded horn or else?

Would be great, if somebody share his design.

Thank you.

Field coil? If so, you can dial in [EQ] the amount of bass by changing the voltage with a variable 12 VDC regulated power supply if you don't have the amp that it was attached to.

Anyway, it's obviously designed for a large, lossy cabinet, so will really depend on what the driver's T/S specs are at different voltages as to how small a cab can be and still make decent bass.
