RAWDATA1 · 19th August 2010, 02:52 AM

Hello,

Sorry if this is not the place, but i was not sure where to post this...
I, lucky one, have been giftet with 4 units of JB Systems Sp12/200 speakers a few weeks ago, and although I spent hours in searching on Inet for the Thiele Small parameters, I couldn't fnd them anywhere.
Everything I was able find is this (not really helpfull):

Technical Details:

Imdedance: 8 Ohm
Durchmesser: 12"
Power RMS: 200W
Frequency response: 60 Hz - 5 kHz
SPL 1W/1 m: 96 dB
Application: Mid / Bass
Weight: 3kg

Anybody has got measured them out or know where to find more info?
Would apreciate it a much as i have not multimeters to do this.

Just tried one of these chassis With an 50W RMS amp, and found they sounds surprisingly (for their price range) punchy and clear in a closed box with not too much lowerbass but a nice spl peak in midbass and goes wide up in frewquency.

Anybody could help me out with the T/S parameters, so I could choose a enclosure design and starting the calculations and craft?
Hope you could help me.

Thanks&
Cheers

No one knows T/s parameters for those chassis?
So do you think some multimeters with 1,5% exactitud would do this job?
Or what would you recommend for this works?
