I just wanted to mention:
Most PEQ units have a max voltage spec because if you add significant boost to the signal the output voltage increases. So, I don't know if Mini means 2V max or what? In any case, the input sensitivity of the clone amps changes with the rear panel gain limit dip switch settings. If yours is set to the default (38dB), the range is limited to around o.5 to 1.2V driving a 4 ohm load. You might want to set the gain limit to a lower setting and use the FP gain control to dial in.
What can I say? 16x18" in 1500 cubes...
That's a single 18" sub for every 94 cubes, which is approximately the volume of a standard 6' x 2' closet. 'Nuff said.
I posted in Carp's thread about my theory for room gain. I've tossed PVG out on it's ear and focussed on actual data. Thanks for posting yours. I added yours and Carp's to the short list for anyone interested:
As Josh and I have noticed over the years (and commented on), many larger rooms show a dip in the 10-15 Hz area and some rooms show a resonance peak from large frame boundaries (vs a room on slab), but the general Room Gain Profiles are (+/-) 2dB, starting in the 30s Hz. Data like this that I've collected over the years is what led me to designing 9 preset curves to mate sealed subs with rooms from a global standpoint rather than some infinitely different room dimension PVG theory.
The rooms are every size from your 1500 cubes to not's 6000 cubes.
Anyway, job well done and thanks for the input in this thread.
