This article was originally published in audioXpress, June Typically, response below to Hz is not possible in reasonably sized rooms. This, in turn, limits low-frequency response. These systems window the time-domain measurement to eliminate room reflections. The power of these systems comes at a price. With the availability of low-cost, PC-based acoustic data acquisition systems, experienced hobbyists can make highly accurate loudspeaker frequency-response measurements without an anechoic chamber.

Thanks to all Good point Kal, I didn't consider that. Quote: I guess I could use the hardware with some of the freeware, no? I guess I could use the hardware with some of the freeware, no? Wrager is offline.
Anyone know how to get a hold of XTZ? I bought the kit and my lap top died so I need the software. Hornresp Tutorials By amateurs, for amateurs! OldPM. If you've not guessed by now - I went the DIY route.
Disclaimer - not all of the meters have responded well to the mods - I am still struggling with the one I am currently working on. Seriously - the electronics are flat from 10 Hz - 20KHz, far better than my ears. It all depends on what you are comfortable with. Is this the same sort of thing as what you've recommended above?

You can import the measurement saved from HOLM. You do need to buy a sound card with phantom power for the M-audio mobilepre USB is popular. As I've said, I just recently have become obsessed with speaker building, and was wondering how I could measure my finished products.
It may all seem easy to replace a diaphragm for a compression driver/HF horn.
