Manger Audio Loudspeakers. Has anyone listened to these?

glennewdick, thanx. I had heard of Voxative but not Lii. Voxative certainly has nuts. $59K for a pair of 8" drivers with leather surrounds no less. But, they do have more reasonably priced units.
I'm thinking an 8 of 10" speaker. The larger driver will beam the midrange more making the speaker more directional which I think is one of the best ways to avoid room interaction. Pulling the deep bass out of it should lower distortion quite a bit. I was thinking of using a pair of Nelson Pass's Amp Camp amps on them, a MiniDSP and a pair of my model 4 subs. Part of the game here is trying to make a killer system for as little money as is reasonable. The Fostex still gets the node for value not sure about sound quality yet. The Lii's are Chinese and I am on a hiatus from their products for the time being.

I have heard the Manger setups at the major audio shows and very much liked the sound. I think single driver or planar speakers do better in the smaller room environments at the shows, as both tend to project a very solid coherent sound for my ears. I am not one for a lot of bass, so I cannot comment on that.

One more unwanted opinion. I did a lot of ob research and settled on the Lii’s; crystal 10 and w15 woofers with crossovers. First time fun and just started and not dialed in but impressed. I am coming from electrostats and a hiatus and kef before that. Little Betsy and eminence alpha woofers is a good entry point for fun. Maybe mark audio. Decware also makes interesting drivers (more expensive) I have not heard any. Visaton 200b . That in short is what I came across other than mentioned.

Good evening... More accurately, a Manger (and Walsh drivers) are 'bending wave transducers' that create a 'ripple' in their surface element, as opposed to pistonic motion of the voice coil on a cone.

In a Manger, this is a flat 'plate' membrane; in a Walsh, a cone typically  inverted & stretched in its' vertical axis.

The Walsh-style driver is used in Ohm speakers, which are omnis in nature.  The Mangers' are used more like a typical driver, mounted on the face of a cabinet.

You might look this over:

Both share the physics behind DML (Distributed Mode) Loudspeakers;  'flat membrane' speakers, which range from the 'poster speakers' (which look like a picture/painting of some size, hung on the wall) to hall arrays; the best of which I've found are:

I find this variant appealing in that two DML panels flank a AMT ribbon driver, very similar to my large ESS Heils...*S*

For one with a reeallly large listening space, one could go extreme:

Better Walsh radiators can be found @ German-Physiks.com, but be prepared for the prices...

http://www.hhr-exoticspeakers.com  ...not only offers new versions of the 'original' Ohm speakers, but offers a 'stand-alone' Walsh radiator very similar to the G-P drivers....

...and quite like the drivers I DIY for my own amusement. ;)

Enjoy your music the way you do, J

@bondmanp , There certainly is, Open Baffle!

@ncdogdoc , Interesting that you heard this and I think you are absolutely right. The reason is probably that these speakers and planar speakers are strongly directional which limits room interference 
Rickderuyter, Thanx, had not hear of those either.

@asvjerry , That is what I was alluding to. The Techtonic drivers have IMHO two failures. They are very inefficient, 82 dB/1watt/meter at best and they disperse over 180 degrees. Optimal in a 16 X 30 foot room is 45 to 60 degrees. Wide dispersion increases room interaction corrupting the image. Wide dispersion speakers add energy from the room at 3-4kHz increasing sibilance. Some sibilance is due to bad recording but most is due to the room! Recordings of female voices and violins I once thought were bad turned out to be fine when I switched to directional speakers.
