Tang Band 2145 in action

Quad 57’s.

~~~~~~~~~~~~~~~~~~~
The Legendary Quad 57’s,
My tech mention this speaker presents the finest midrange he’s ever heard.

Which backs up my hunch these 2 WBers midrange has authority and eloquence.
Equal to any panel/stat’s supreme mid voicing.

~~~Futhermore,, while looking for Bache's links, I notice you left a  customer comment and states all the top class speakers you've auditioed in the past.
Thats quite a  top notch quality of speakers you mention there.

Again , my hunch the midrange in this TB2145  excels over the  mids in the xover low sens types due to inherent weaknesses, which a xover can not mend nor  fix.

OK Found Bache Audio site
His latest 
Bache Audio 002AB, is really full complete total  range speaker.
Thats one heck of a  tweeter.
Only says (Paper Tang Band** not sure which model.

And i am quite sure  the reviewer got it right, beats the Dali and Wilson in the critical midrange....where is counts...
High tech WBers always come out the winners in  seamless lifelike soundstage  in mids,  vs the xover low sens types. 
You can argue that point all you wish, I ain't budging 1 inch on this  doctrine.
 My dogma is based on experience.

Magnesium, worlds best material for midwoofer cone musical resonances.- mozartfan

It's an unfortunate situation where though it's true that magnesium makes for an exceptional sounding mid-bass driver, it corrodes easily, uncoated.
It sounds much better uncoated than coated, or at least that's what was found to be the case with the Seas Excel drivers.

it corrodes easily, uncoated

~~~~~~~~~~~~~~~~~~~~~

I always wondered,,how a cone  is made of magnesium...??? I think of magnesium as some sort of mineral, like stone or something.
The cone has this spongy type feel to it,, PERFECT for absorbing unwanted nasty upper mid fq’s and as well low mid fq.s
But  gives up some deeper/tighter  DRUMs punch that the ScanSpeak Revelator exhibits. 
Small trade off.

OK just looked more closely at

~~~~~~~~~~~Wilson’s Sabrina...
has a 5 inch paper midrange..
Both my tech and I had our share of the old midrange drivers back in the day.
Neither of us cared for any of the dedicated midrange voice.

I am sure Wilson’s mid driver is superior to the old models,, but is no match for the Tang Bands’ xover-less mids.

Take a look my site all my speakers based on Tang Band 2145

~~~~~~~~~~~~~~~~~
I just did. I really like  your latest 002AB model.

I'm sure your Fostex tweet matches the Dali super tweets.
In bass I;'m sure your bass drivers match/surpass Wilsons' dual woofers.

But again, for my needs in classical music, its all about midrange. 
Here is where you gain the advantage with the Tang Bnad 2145,,,on your site you mention  **Tang band paper driver***, no where did I see 2145..
You might want to update that bit of info..
This way potential buyers know the driver is not the 1808 and 1772.
Its my hunch  the 2145 is the superior speaker.  vs its 2 siblings, 1772/1808.

Great work on your true full ---complete total--- fq design
Sens is super high, fit for any amplifier. 
I'm running the  Tang Band 2145 with a  Jadis Defy and a  EL 34, both pack power and work  with good results (vol gain no more than 9 oclock, =  mid SPL (80ish)in my small room) with the high sens WBer.
Ideally maybe a  SET is superior, but any  sized  PP will also work.
I listen at 8:30 on  the Jadis DPL line stage vol....near field,  . seated 8 feet from speaker. 


After owning the Seas Thors some 15 yrs,, its such a  good feeling have a  WBer on the speaker lines.......
Niceee
