Anybody knows anything about this drivers? anyone who's heard them can post anything about them?

Now, I have not received any marketing or business training per se, but if you ask me that's not exactly the best title I would use to describe a speaker!

LOL, didn't realize... oh well.

Here's a review:

And here's a source for the drivers:

A "very fast" amp is recommended.  The new digital amps should be perfect.

And a first order crossover at the bottom end.

The VBT subs look like a natural pairing to the mangers for their speed.


The only negative I see is the lack of typical distortion for playback of some musical genre.  But I had a speaker designer tell me 30+ years ago that reduced distortion is probably a good thing for rock/etc.  


Definitely worth a listen, but where would you go to hear them?

[nathanm]

In all seriousness I was curious about these as well awhile back.  They must be something phenomenal for the prices they're asking - yikes!!!  Certainly has an interesting look at least.

The review was nice, but it concerns me that I didn't read anything about detail levels... He said they are warm and non fatiguing which makes me wonder about detail speed and acuracy, which he does not go too much into...

U right definitely need to listen to them specially at that price... the drivers alone are close to $700 on e-speakers each!

How about a 7 foot tall line array of these babies croseed over at 80Hz?
It'd probably make a smoking system for about $50k in driver cost alone!

PS I'm assuming that it acts as a continuous membrane and not as a point source otherwise it'd be comb-filtering like a mama!

[JLM]

Mama combs filters?  Cool!  

Their zerobox concept requires (3) $680.00 drivers per speaker (front, right, and left firing) and you'd still be missing the bottom 2 - 3 octaves.  I'd say go for six drivers for a true omnidirectional point source from a 12 inch cube that could be supported at the corners by small cross section metal legs.  Thats only $8,160 for drivers plus some Corian for the cabinets, add some chrome plated open stands on 24 inch square plinths and your favorite powered sub.  Throw in the typical 800% mark-up and now we're cooking at around $100,000.00 USD.

Detail/accuracy is their forte.

If you're building your own speakers the driver cost can be absorbed.  I like those single driver versions they show with the corian baffle curved back slightly.  Don't know why you couldn't make something similar with some sort of straight material (countertop, plywood, MDF, etc.) for the baffle and make the box they show for a cabinet.  Just add a powered sub with a high filter.

I understood the drivers that are not on the front are not used up high. At any rate, putting a driver on every surface is not really acting like a point source at higher frequencies. For the cost of three Manger drivers I'd look into a line array instead.

I was quite interested in the drivers at one point. Further research (ain't the Net great ) seemed to reveal that they were particularly fussy wrt amplification, as you've said, but without more explanation that was certainly a big question mark. Also, there was a question of where a good crossover point was because of the limited displacement. In the end too many question marks and too much hard sell from the distributor.

[NCF]

In theory they look good, the only thing I see is the phase shift between the frequencies since you have to wait for the impulse to move outwards for the driver to start producing lower frequencies. Not that regular drivers don't have their own phase problems...
