Manger Audio Loudspeakers. Has anyone listened to these?


I am particularly fond of full range loudspeakers. I am not terrifically fond of whizzer cone designs because to make them work you have to decouple the main cone from the voice coil at high frequencies, a mechanical crossover.
As I understand it, the Manger driver is a flat Walsh driver. It will cover 120 Hz to 40 kHz! This will just make it down to subwoofer territory. Other full range drivers include Cube Audio and Fostex both of standard construction and both decouple the voice coil from the main cone at higher frequencies. Is this really all that bad or can it be done maintaining high fidelity? I have not heard any of them. Both the Manger and Cube drivers are very expensive, in and around $5000 for a pair. So, I can not afford to experiment. The Fostex is cheap in comparison but it looks well made and specs fine.
I plan on making a pair of open baffle "full range" speakers crossing to subs in and around 100 Hz. Which driver to use?

@asvjerry, an afternoon at my house and that would change:-)

Most speakers are more or less omnidirectional. The penalty is a lot of energy is wasted bouncing off walls going everywhere but the listening position and you have a more complicated and expensive room treatment situation. You can however make it work. I have heard it work in a stupid small overtreated room. Go figure.

Too directional (beaming) is a bad situation with which I lived for over two decades. Only one person gets high frequencies from both speakers and there is absolutely no image off center. This was the main reason I had my eye on the Sound Labs for around 10 years. Which in my room is perfect. Everyone in the seating positions back hears everything from both speakers. My desk is in the back of the room on a side wall and the sound is much better. Sound only bounces off the side walls behind my listening position out of harms way. Since there is no back wall until two rooms later I get the ambience of the whole first floor. It sounds like a small jazz club. 

I have to use an array of subwoofer in order to match the radiation pattern of the main speakers which are line sources. Two subwoofers get are a pain. You have to keep matching levels as the volume ratio keeps changing with volume. With 4 subwoofers forming a line source I can set their level and forget it.

The Ohms do mid bass fine it is in the region where they crossover from pistonic motion to wavy vibration that things get messy. I know them well as I sold them when I worked for Luskin's in Miami. They offer a different color than other speakers in their price range so, I can understand why some people like them. They are not true omnidirectional speakers by the way. High frequencies are limited vertically. If you were to sit down too far away from them you lose high frequencies. This is actually a good thing IMHO. You also have to take the covers off. The corner posts really screw things up. 

Listen on! 
*L*  Well, I reserve the right to temper my 'changes'. ;)
But we could have some sort of good time. *G*

Distributed subs reminds me of one touting the DEBRA sub array with 5 units. Not huge drivers. either....curious enough to try.

I've literally done a Walsh 'surround' array with a single sub; it displayed interesting 'characteristics' that I'm compelled to explore.
Even if it's only for personal grins and enjoyment.

I'd bet I could get your attention as well....en guarde! *L*

No fat corner posts for me, no.  Shafts, minimalist.
Better hf by lowering the entire unit...almost too simple.
Better hf #2 is going 2way, a Walsh tweet with Walsh mf drivers.

I have a small pair I use as my main 'puters' monitors, with a small sub under desk....

Haven't blown them up yet. but there's no reason I should either....*G*

I have the Manger S1 active speakers. They were damaged in shipping having one of the amps crap out. Before the amp went out I did get 5 hours of listening time in. Stunning sound and made my Audiovector R3 speakers sound lower class. Very fast, Quad like sound but with bass and dynamics. Quiet presentation with no distortion.
