you should specify if your wanting to measure to get the t/s parameters or if your intending to measure output with a mic.

I would like to measure both: speaker frequency response and driver T/S parameters.

Thanks.

Check my home page, http://www.claudionegro.com, there is a tutorial on Speaker Workshop (freeware), for electrical and acoustic measurements.

The ATB PC Pro is on page 18 of the Meniscus Audio catalog (www.meniscusaudio.com) for $219. You might give them a call to ask about it. They talk about an add-on PCMCIA card availability 'next year' for a pro version of the program. Don't know about compatibility with your computer but it does come with a calibrated mic and looks complete to test as delivered.

Another way to go is to use Soundeasy (measurement and design software) which is availabile from Parts Express, E-speakers, and other places around $240. S-E needs specific sound cards to have full capabilities (the emulation ability) so look before leaping. Also you will need a mic (the Behringer ECM8000 is $50 but uncalibrated) and perhaps a microphone preamp to get started.

The Woofer Tester (www.woofertester.com) for $150 for T/S test has a pro version coming soon which may add more than T/S testing capabilities.

Soundesay has an active support forum and the woofer tester support seems active as well. Don't know about the ATB PC Pro but likely much support from European users.

speakerworkshop and the (somewhere available) huge manual that was written for it.

VERY powerful software for the best price: free

For acoustic measurements, I use a Behringer ECM8000 w/ Behringer UB802a for a preamp, which I bought from a forum member for only $50.

I couldn't realize the full potential of this measurement setup until I purchased a good soundcard. I bought a used M-Audio Delta 2496 for only $25. This thing is great. Being able to sample at 96khz is very useful when taking gated measurements.

For software, I use Arta for quick measurements, and Speaker Workshop for extended projects. Both were free.
