Manger Audio Loudspeakers. Has anyone listened to these?

I used to be one of the very few dealers of Manger in the U.S. many years ago. Their uniqueness was attractive but I never got behind selling them. Did not care for the sound. Did not think they were very musical.

Something for thought; - - - -  regardless of how the sound quality is perceived by a given listener, and regardless of the fact the it will undoubtedly need a sub-woofer, which is not unusual, pertaining to many speaker designs being offered on the market today, my real concern here would be, availability of dealership interaction, if needed. I may have missed something, but I can only determine (1) US based dealer. That fact alone has sent me in the opposite direction from considering several speaker designs that are quite credible sounding. I certainly don't want to have to factor in accessibility and credibility of a dealer along with a somewhat obscure design/manufacturer of speakers. I had a problem with a very finely reviewed OPERA speaker, some years ago. Very scant representation in the USA at that time. It took many months to resolve the issue, having to deal with a manufacturer in Italy. Just something to think about before " jumping off this particular bridge".  GOOD LUCK ANYHOW.

axpert, I totally understand your apprehension. I feel very much the same way. People have been messing with speakers for over 100 years and there is nothing mysterious about the engineering. New materials and CAD have improved the engineering but products that go off the beaten track should always be suspect and treated with a degree of caution. Thus, my inquiry about the Manger. It is a very different approach and I am not hearing a lot to recommend it although it is rather rare in this country.
full range drivers have several advantages. They are a perfect point source. They can be made to be directive without beaming. They are phase coherent. The big "but" is that as soon as you ask them to make low bass you force them into making long excursions which force the suspension into the non-linear portion of the range increasing IM distortion and you add doppler distortion on top of that. Pull the deep bass out and you have a remarkably different situation. The same mistake is made trying to make ESL do bass. They can do it but the penalty is very high if you like to listen at realistic levels and I do not mean Rock stadium levels. I mean jazz and symphony orchestra levels.
Ths became obvious to me back in 1978 when I started in with Acoustat Model X's. They made wonderful bass as long as you did not take it up over 80 dB. Then they started farting all over the place. Randy Hooker had just come along with his Helmholz resonating subwoofers. A pair of those with a Dalquist Crossover and two Kenwood LO7M amplifiers gave you state of the art bass of the day and let the Acoustats do what they do best unhindered. I have not changed my approach in over 40 years.
I have never tried it in the context of a small, very efficient full range driver
but I can not see why it would not work wonderfully. It will give you a smaller image but would fit much better in smaller rooms than honking huge ESLs and would cast a lot less. Building a SOTA system for less than $10K for the preamp, amps and speakers would be quite a stunt.

@axpert   BINGO! "The Ghastly Truth". +10  Thank You. *S*

@mijostyn... "...Then they started farting all over the place."

Yeah, I hate that....the 'acoustic stink' just drives one out of the room....;)

Same with what I play with....the 'original Ohm/Walsh variants, victims of the 'tech' of the time., 'Great@200/AWOL@201 watts'.

If one directs the lowF to a sub...better, an array, more so.....
If one unleashes the main cone from that chore.....;)

It gets better...but I have no short stories, anymore. ;)

HO, the Manger competes with German Physiks as to high accuracy reproduction in two different approaches as to 'how' being one prefers to have music (or anything else) reproduced feels...'appropriate'. *S*

The Mang' don't get 'exposed enough'

But I'm an 'omniperv', and Proud of it. *G*;)

@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!
