Anyone familiar with the Manger driver?


Sounds like a new and innovative approach to a speaker design. The big question is, HOW DOES IT SOUND? Some interesting stuff on their website MANGER, but I'm curious to know the impressions of people who have actually heard one...I didn't make it to the CES this year.

Jack--your question is a bit incomprehensible. IF I get the gist: Mangers in a p.a. application, I'd say forget it. You don't have the the spl capacity in the first place.
Larryi the Mangers are 8" (they do look small). But yr comments still apply!
D_edwards, can you describe your Manger application -- the speaker part, the dsp part is obvious? BTW, that 10' paper scan is not a bad driver in & of itself.
What did you use?
Cheers
My Manger project utilize 2 dual voice coil Scan speak 8" Kevlar (100watts per driver perside) and twin tower 2x15" JBL woofers (total of 4).
Now that's what I'd call refreshingly serious stuff!!
I assume the Scan was a 8546 - but w/ dual VC -- filling in midbass b/ween Manger & JBLs?

Actually, a contemporary Manger I tried briefly has a smooth pattern in the mid/upper-region (s/thing bumpy ~7kHz, never figured out what it was).

Thank you for the descrip.
Sbfx -- the diy you present reminds me of the those Audio Physic Medea I had many years ago.
The diyer probably achieved better implementation I assume...
These distortions, unlike simple harmonics, are non-mathematically correlated, and occur in time AFTER the musical signal
Quite so. However, and apparently, these can be modelled -- but only with reference to electromechanical properties in each specific application. Unfortunately, I can't find a ref you may be interested in.

BTW, a simple experiment with very hard cone material coupled to powerful electromagnetic support, may reveal an "overdamping" effect (i.e. relative spl drops faster than projected -- further i.e., what we call "decay" is truncated, becoming "sub-audible" if I may coin the ugly word).

A very interesting viewpoint, Martin.
I hope you test on open baffle and measure below or at 30ms.
Of course, without interpolating passive components. Since you're using a generator, limit the bandwidth if necessary.
It's a wide-range driver and, depending on the application, it can be used down to 300-200Hz. It has an unusual sound; in some respects it's reminiscent of a ribbon & in others of cones. DIspersion characteritics are also somewhat unusual compared to a conventional cone. People who have tried working with it (N Pass is one of these) have had difficulties in getting the speaker system dispersion pattern right (among other things). The side firing mangers seen in some systems are purportedly there to smooth response from ~2kHz downwards...

I forgot: it's also an expensive driver so, if you're thinking of a diy scheme, check out a discussion at diyaudio.com. E-speakers sells it in the US and has some specs at the site.
