Does this Peerless 6in look familiar? Neo magnet? Underhung design?

Does this thin look familiar to anybody? http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=3329028888&category=21994

First of all, I can't see any ferrite. Then, a Bxl of 10.56 Tm is enormous for a 6 inch. Last not least, 12 mm gap height and 6 mm VC heigt means its very much underhung. Quite unusual, isn't it?

There is also a self-styled data sheet at:

Whats the problem? Its not 6inch, it says it is 5inch... and it is magnetically shielded...

6,5

Hi
133cm² is more like 6.5" than 5"!
most 6.5er have less cone area!

But it says its 13cm, there is no way its 6inch if it is only 13cm.. lol

Me thinks these numbers are made upish...

I did, and thats where I say fesonany frequency of 74Hz... too high for a 6.5inch if you ask me...

The 130mm Peerless mid-woofer has a fs of about 55Hz...

 

[uli]

why?
I know 10"ers with higher Fs

oh I forgot:
for a given manufacturer the Fs/ diameter relationship
is a CONSTANT

Actually, it is pretty much.... and I doubt Peerless would make a 6.5inch driver that ugly... all their "square" drivers have the same "inverted?" rim around the edge of the frame.. lol now I'l just reaching at straws.. lol 🙄

focal

take a look at the Focal mids & midwoofers in the 6-7" range.
It depends on the intended usage range. There you can find
6" woofers and 7" pure mids.
