If anyone orders one let us know how you like it.

If anyone gets one in the SF Bay Area, I would be interested in comparing it's results to those from using Clio.

I have the original and it is a great bargain for use at home.

Just happened on this today -

BassBox 6 Pro Changes
Version 6.0.20 changes (29-Mar-05):

• A new import filter was added for the Woofer Tester II. It can import the measured Thiele-Small parameters from "log" files created with the "Export to BassBox" command in the Woofer Tester II's File menu.

X•over 3 Pro Changes
Version 3.0.15 changes (11-Apr-05):

• Removed the driver polarity from the impedance net plot line calculations when the phase is included. This is because the driver polarity does not affect the impedance presented to the amplifier.

Version 3.0.15 changes (29-Mar-05):

• A new import filter was added for the Woofer Tester II. It can import the measured Thiele-Small parameters from "log" files created with the "Export to BassBox" command in the Woofer Tester II's File menu. The new Woofer Tester II can measure both open and sealed back drivers (woofers and tweeters) and the import filter allows data to be imported for any driver (woofer, midrange or tweeter).
• A new feature was added to the System Impedance graph. The user can now control whether the net impedance plot line is summed with or without the phase in similar fashion as the net amplitude response plot line. The feature is controlled with a new net impedance "ø" (phase) checkbox on the "Graph" tab of the Preferences window.
• The calculation of the band-pass filter of a 3rd-order 3-way crossover network was tweaked to provide a better response on the low-pass side of the band-pass filter.

Could be fun I suppose.

Dang it! I just recently got BBP6 and XO3 and now you're gonna' make me go out and get sumpin' else...

Yeah. It's cheaper than the orginal Tester was though and supposedly considerably better. The only thing left to get would be an RTA to check real world results. Gotta love being able to run all this crap automagically. I think Robh3606 already has BB6P and an RTA

Other uses which might not be so obvious would be inductor triming and quick measurement of enclosure tuning frequencies. The USB hookup makes it easy to use with laptops on the go.

I went ahead and ordered one to play with.
