Neat Momentum 4i Iso-Baric?

There is a pair of these listed on AG and they have my interest. Can someone explains the Iso-Baric feature, pros/cons, are ther other speakers with this feature?

I currently have the following speakers in use at home: Spendor SP7/1, Dynaudio Contour 1.8 MKII and Vienna Acoustic Mozart. Using respective amps: Prima Luna Prologue One, Marantz MA700 Monos, Primare A30.1 Any comparison to these would be helpful.

Experience with Neat is with the Critique Pros bookshelf, a favorite bookshelf without consideration of price.

How do the Momentus 4i compare to my other speakers and what amps listed are the best match?

Thanks!

Thanks for the replies, but the Momentum 4i are no longer listed. The listing doesn't even show up on a google search.

Isobaric also called compound loading is basically two woofers mounted front to front or front to back with a very small airspace between them wired so the the cones move in the same direction. Advantages are half the distortion and that the pair only need 1/2 the cabinet volume behind them to achieve the same bass output. Disadvantages are half the impedance and the fact that you need two woofers.

In my Montana EPX i use this technique, each box use 4 woofers, 4 ohm wired in series parallel for a combined impedance of 4 ohms - tremendous bass out put for a relatively modest sized floor stander.

As always, good listening
