In Reply to: do you have a published impedance plot on the Mani 2?... posted by kuma on May 6, 2007 at 10:03:27:
KumaThe impedance curve is in the UHF magazine
http://www.uhfmag.com/Issue76/UHF76.pdf
Page 31 has the graph. Link Below
Impedance curves don't tell the whole story.
There seems to be an undefined (as of now)
factor(s) involved in driving real speakers.
I have designed/built many speakers with
Dynaudio and other drivers and realize this.
My favorite tweeter is the D260 - I have 4.
My brother prefers Morel tweeters and mids
and Dynaudio as the woofers in his bedroom.
He has Maggie 2.7s in the living room.
Maggies have a fairly flat impedance curve but
many have found using the Zero autotransformer
does wonders for the bass by increasing the
impedance seen by the amplifier.
This is the same factor I am proposing.
Amps Current Capabilty vs Speaker Impedance Load
Higher current capability of the amp and
higher impedance of speaker are two ways
of accomplishing the same results.
Some speakers are more susceptable to this variable
while others seem to care less about it.DanL
Follow Ups:
Having tried the speakers, I was just curious.I agree that the impedance plot alone does not determine how successful speaker/amp pairing would be. There are lot more factor involved.
http://www.stereophile.com/loudspeakerreviews/462/index7.htmlIn keeping with this thread's discussion I would post John Atkinson's Note as well, from the same page:
"In my original review, I concluded that while Totem's Mani-2 appears to cost a lot for a conventional-looking if well-finished minimonitor, its combination of clean treble, transparent midrange, natural dynamics, and powerful, extended bass allowed the music to communicate in a most effective manner. Although the current sample is a little more forward-balanced in the upper midrange, the Mani-2 is still enthusiastically recommended, particularly if you have a smallish room, value bass extension, and are prepared to pay for it. A solid Class B loudspeaker in this magazine's "Recommended Components."
NO wonder! :0
