Keep in mind Joe when comparing bass of Duo vs 4367, one is passive and the other powered. The passive would be subject to the amp used.
I have to say your enthusiasm is enough to make us all lust for AG, LOL It would be cool to have four 12's in my room and if the compression driver is better, so much the more.
What does the DSP do, is there a microphone or some way the speaker compensates for the room?
The EQ allows for selecting the curve, setting the crossover and adjusting everything below 150hz (in the case of Duo). It allows you to set up to 40 or 50 different presets if you want (I only use one). You can adjust over all bass level. It’s very powerful and dial the speakers into the room. I play pink noise and use my own microphone and software to determine measurements.
