Hi guys,
I run a couple of 4645B subs
Sound is great, punch is amazing but i expected some thing better on the very low frequencies.

After a tone test it is no present anything under 33hz
I was expecting to reach 25Hz

First doubt are the actual amplifiers that are some pro module from Mackie subs and could be they have some EQ / hicut built in. I'm moving to something like QSC, Crown, Carver.

Second doubt is the room to little (8,5mt x 4mt)
that doesnt allow frequncies blow a certain Hz.

Any help pease?

I'm considering also to use the two 2242 for building a TCB clone unit, maybe better for extreme low freq.
