Crossover measurements

[maxover]

Hi all,

I have recently come across what I think could be an interesting tool for crossover measurements:

EasyTF

EasyTF is a complete solution for measuring transfer functions. It makes cross spectrum frequency analysis available to hobbyists and smaller companies on a restricted budget.

What do experts here think about it? Has it got any chance of being useful for an amateur builder like myself?

Thanks,
Max

Outrageous price for this.

Just get HolmImpulse for free.

Nobody use "cross-correlation" techniques anymore. Completely obsolete.

HolmImpulse is designed for 32bit windows OS up to Vista (yuk!) but runs in win7-64 (marginally better).
Looking forward to a Linux version.

I use Holm in Windows 8 64 bit and it works fine. I doubt that there will ever be a Linux version since the author is no longer doing this software.

Dayton Audio DATS Dayton Audio Test System 390-806

..measures driver T/S param.s, driver impedance magnitude and electrical phase, crossover components, and a few more test conditions.

UMIK-1 | MiniDSP

..provides a mic, calibration file, and sound card all in one via USB port.

-Impulse Response measurement program of choice, which could be HolmImpulse (as Earl mentioned), or Arta, (both of which can be "freeware"), or perhaps something else.

Xover xfer functions can be measured using the WTPro. Howver cost is similar to the OP's unit.
