@teajay i was pretty sure that as the order goes up the group delay went up, and the things that went along with slowness, muddies, and the other subjective things.
And why people like transmission lines, infinite baffle and sealed boxes.
WinSD does give group delay for a variety of boxes and used the driver’s Theil-Small parameters.
Major innovative break through: The new NSMT Loudspeakers reference speaker
In the next two weeks my Stereo Times review on the new NSMT Loudspeakers reference System Two will be posted. I wanted to give a heads-up to the GON members because I consider the System Two, which is composed of the Clairvoyant Monitor and SUB-DUO active band-pass subwoofer platforms to be a revolutionary break through both in performance and retail price $15,985. For example I compare the NSMT System Two to a great speaker, the Stenheim Alumine Five SE Dynamic Loudspeaker, and found the NSMT System Two to be superior in it's performance. Punch line- The Stenheim Alumine retails for $72,000! For all the details of why I came to the above conclusions take a look at the review when it is posted.

Hey holmz, I'm pretty knowledgeable, but first to admit I am not a designer or electrical/acoustic engineer. With your concerns/questions about band pass active subwoofer design I recommend you give a call to Erol to discuss. I'll also ask him if he would want to put something on this thread addressing your questions. Based on my experience, ported, acoustic suspension, or infinite baffle subwoofers (have had highly regarded and very expensive models in-house for review) come no where close to the natural pressureization of my room delivering a spatial presentation that is a more accurate illusion of live music. Secondly, the blending of the upper bass frequencies with the lower midrange is more seem-less giving the "power range" foundation that allows a system to have a sense of authority/control.

The review on the NSMT System Two speakers earlier today was posted on the Stereo Times website. There is a slight glitch for now, I'm sure it will be corrected shortly by the owner Clement Perry, that the review appears in the archives section under speakers, instead of on the front list of current reviews. So, you have to click on the archives section under speakers to assess it. I hope you all enjoy the review, I explain as clearly as I could why this is a terrific speaker in so many superlative ways. You can start with the monitor and add on later the two different band pass subwoofers as your budget allows. If your shopping in this price bracket, between $7500 to $15,000, you owe to your self to audition this design before you make your next purchase. Thanks, Teajay (Terry London)
