DBC - I am using a speaker level connection from the Zen to two (2) separate Rythmik A370PEQ plate amplifiers, 375w each into 4 ohms. The Augies in each channel are wired in series to present a 4 ohm load to the plate amps. The plate amps can crossover as high as 120hz with (I think) a 12db/octave slope, but no higher.

ProggRob,
I don't have personal experience with the Augie's. My Mid Bass Modules and the Omega DeepOmega Sub have very light 12" driver cones for speed at the higher frequencies. Not sure if the 15" Augie's are light enough (fast enough) and that may be the reason for the Muddled Bass at higher crossover frequencies.
I have a pair of HSU ULS-15 Subs (15" drivers). These are great Subs at a crossover of 60hz & below. As you describe, they get what I call Flabby around 80hz & above.
So I'm not sure why you are not able to achieve the same performance as quoted by the reviewer comments below?
Quote:The 15” Silver Iris Augie was well reviewed by Dick Olsher of “Enjoy the Music.com” Following is an excerpt taken from his review of the 15” Augie. “It seems to me that many listeners confuse bass weight with bass extension and opt for a subwoofer when bass weight is lacking. The problem typically lies in the upper bass, the octave from 120Hz to 240Hz where much of an orchestra's foundation and acoustic power resides. This is the octave that box woofers have a hard time coping with, basically managing to sound boxy through this range. In contrast, the Augie managed to shine here, elucidating instrumental fundamentals with consummate clarity and 3D realism.

"It seems to me that many listeners confuse bass weight with bass extension and opt for a subwoofer when bass weight is lacking.

I've always said I would choose the Mid Bass Module over a Sub any day of the week because the reinforcement up into the 150hz range is where the Weight is.
