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

Today, my review on the NSMT 20M Armada speaker was just posted on Stereo Times. It will give you all the details regarding way this two piece (Monitor mounted on a band-pass active sub-woofer pedestal) is a superlative full range speaker.

However, if you love your monitor speakers you owe to yourself to read the details that explain the difference between adding a pair of sub-woofers vs. a pair of band-pass sub-woofers, because their effect will transform your monitors seamlessly into a full range system. Not just bass extension, but because of how a band-pass active sub-woofer fills in the power range (lower mid-range/upper bass) and also pressurizes your room so all the ambient cues that create, both power deep accurate bass and a vast panoramic layered sound-stage. I ran a detailed extensive process involving over ten monitor speakers with a pair of excellent sub-woofers compared to the MSNT band-pass sub-woofer pedestals, and every time the sonic "magic" took place that was quite different then using a pair of sub-woofers. If you own Harbeth or other highly regarded British monitors you will be amazed what will take place in your listening room. There is also a detailed explanation that lays out the difference between an active band-pass design and a normal sub-woofer.   Terry London/Teajay

Dear @amorstereo :There are some critical issues in that set up that are wrong:

first is that any two way speakers with concentric tweeter or not and running in its full frequency range develops very Intermodulation Distortions and this means that midrange/hig frequencies quality performance is non-adequated.

The main target when using subwoofers with those kind of monitors is to lower that high IMD using a high-pass filter to liberate the monitors of bass frequency response from 80hz and down and at the same time to have a true excellent bass range performace, this bass range is the foundation of the Music system reproduction and as better the bass range of the system as better its overall quality performance.

That " band-pass " kind of set up does not avoid that developed IMD and even makes it worst with added bass unit crossing as band-pass and I say bass unit because that is not a true subwoofer.

I'm using two true subs and I have first hand experiences on what I say.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

Hey rauliruegas,

I would be more then happy to discuss why your analysis of IMD is not correct, if you want to Email through AudioGon.

What I really want to share is that two more listeners brought their monitor speakers to my home to hear them with the NSMT band-bass subwoofer platforms and both were totally enthralled with the combination! Both want to purchase a pair in the near future. When I asked them what they heard that was an improvement both had similar remarks: 1) Can't believe the vast sound-staging with a sense of the original recording venue as part of the over-all perspective. 2) Not just bottom end extension, but a sense that the foundation of the music was much more there, but perfectly blended with the mid-range in a seem-less fashion.
