Default Guess the driver

Can someone with technical experience let me know what they think about a driver with the following T/S parameters as measured using the DATS system.

Qts: 0.582
Qms: 3.923
Qes: 0.683
Spl: 86.5
Fs: 74.69
Re: 4.6
Sd: 53.8
Vas: 4.58
L: 0.09
Bl: 3.59

Then guess the driver. Thanks

And have you ,by any chance,misplaced the decimal point in the Sd and Vas values ? I get the distinct feeling that a cheapish 8'' speaker has been measured.

No...not the CHR70.

Run the parameters through Winisd Pro or other favourite speaker software and see what you get.

It looks like a 4 inch or something driver, good spl for the size.

Yep, 4" driver, and I can tell you as I listen to them they are remarkable little drivers. I never imagined that so much depth of bass could be produced from such a little driver.

No more guesses......?

FR curve - or would that be cheating?

Some of us have worked with the late lamented CSS EL70, FR125 and VWR126, and are quite aware of the bass that is attainable from drivers in this weight class.

Hmmm...I believe I have all of those.

EDIT: Nope I have the WR125, which is even better in the bass dept. than the FR.
