If you own quality monitor speakers you want to read this new review

I’ve been using MB columns (active band pass 80-300hz) for 10+ years and GR servo bass (60-80hz and down) for 3 years. You call them Band pass, we called them Bass Bins. I had a pair of 500 lb 20 cf tri-pole Bins.

They were made for a dance floor. You could point a single pole UP or forward or against a wall or back to back the units in the center of a bowl venue. There use to be a lot of dancing on TOP of those speakers
around harvest time.. :-)

100 x 100 x 20 shop, they would pressure the whole thing..

I still use my Velodynes. Active, with DSP continuously variable high pass and low pass, volume adjust, contouring adjustment, and phase angle adjust, as well as remote control, to adjust from my listening position. 2005 15” DSL model. 
So this is an OLD idea. Nothing new here.

Hey wolfie62,

Gezz, I wish you and some of the others posters would read the details in the review regarding the differences between regular sub-woofers, like your Velodynes, and how an acoustic band-bass design are not the same thing. Your subs use DSP to control certain frequencies, instead of loading the driver in an unique fashion in a ported box which leads to a very different loading of the room by the device. I have used excellent pairs of sub-woofers for years with monitor speakers with excellent results. However, they never reproduced the weight/foundation of the power region in the music and allowed the spatial cues to effect the sound-staging to evolve into a three-dimensional illusion that the monitors completely disappear in. I could allows "deal-in" the subs, no problem in my listening space(s) and they worked fine without mudding up the mid-range's timbres or clarity. The NSMT band-bass platforms are a different approach and deliver sonicly a vastly experience then a regular active sub-woofer. In the review I asked the designer, Erol Ricketts,to explain the differences and why he chose to use this design in this model.

My excitement over these platforms is that they just don't take a reference level monitor's performance and add bass extension, but transforms them into delivering in a way that usually is only done by large multi-driver floor-standing models without losing any of the tonal purity and sound-staging magic of small two-way designs.

Amorstereo, what is meant by "bandpass." Are you saying that the crossover in the pedestal is rolling off the bass to the monitors?  

Hey mijostyn,

Please read the review for the details/explanation you asking about. There is an extensive/detailed explanation by Erol Ricketts, the designer, that I requested he contribute to my review for the very reason you are asking your question.
