Anyone familiar with the Manger driver?

Well EssentialAudio I have to ask based on this comment, cause I am assuming you actually know something technical about audio gear not just brand names.

"That is not to say the Manger drivers do not have their merits"

Like what? What are their "merits"? You should be able to rattle 5-6 things that make the Manger unique.

I cannot write an experience for you but no SoundLab is ever going to win an award for clarity, not with the reverb off the back wall (100% distortion), and when you can get 110db out of your speakers at 30hz call me, cause that is bass output performance commiserate with a $30,000 speaker system in my estimation. Just don't break anything trying, its not that important. :)

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

Hey Greg,

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).

Manger and paper allow for an easier passive crossover but the paper is a distortion liability in higher performance systems, and with Accuton and Seas using very rigid cones and better motors today, the speaker could be significantly better than what I built, waaaaaayyyy better.

That's not to dump on a Zerobox 109, 107, there are many speakers inferior to it, but in my opinion if you're not using advanced DSP methods, then you cannot get the best from the Manger driver.

The Manger driver today looks to perform about 70% better than the one I used, the DSP was used to control dispersion in the high frequencies and flatten the response to with +/- .5db throught the mids, with todays computing power the transparency of the DACs, the Manger can be realized to its fullest potential. I know why I stopped using the Mangers, but it appears those issues have been smoothed out and have become stabilized.

BTW, there's is nothing obvious about using the Manger, it was not like I bought the parts and the next day I had a speaker that was good and was on the U-1 level, more like 2-3 years later. You don't slip this driver in and suddenly you're a speaker design genius, infact its quite the opposite. All sorts of little nasty surprises that on other speakers could be ignored but are revealed by the superior performance of the Manger, simply cannot be overlooked. The Overkill guys would likely have even better stories and maybe some measurements. I have no records of my early projects and I can't even remember who I sold the system too. Some guy in Frederick Md.

BTW, you better have the "right" amplifiers, Nelson Pass does not make the "right" amplifiers for the Manger which is why he couldn't get it to fly. Manger is a tricky beasty that on paper looks like a plug and play miracle.

it is a trap. :)

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.

Hey Guys,

A bit of updated info re: the Manger driver.

Daniela Manger has indeed further refined the driver which is now quite linear in response and impedance. Much easier to drive and achieve even more spectacular results.

Now the caveat, since the driver is lightning fast, an amplifier that can keep up is optimal. However, superb results can be obtained with many amplifiers out there on the market. Contact us if you have questions about a specific model.

I have always preferred what ESL, Ribbons, etc can do well and I find similar qualities in the Manger. And without the physical size and required room dimensions. Even the 2-way ZeroBox 109 (19" tall) with the 8" ScanSpeak carbon-bass driver that takes over at 140 hz is extraordinary. The 109 puts other much more expensive loudspeakers to shame in all the audiophile areas and yet sounds so naturally real & live.
