Hi All,
I have been experimenting for some time with the Audua labs "Speaker Workshop" and a DIY microphone for doing psuedo anechoic frequency response testing with mixed success. The system is not very accurate, often gives spurious results and I don't have a lot of faith in the measured responses.
I have decided to bite the bullet and purchase/build a professional FR test setup so that I can measure the performance of my speaker designs in near real time anechoic conditions. I have a small testing room which I plan to coat with anechoic tiles but I need the test system.
All I want to do is on and off axis FR testing and I want the results to be repeatable and the system relatively easily to operate. I don't need super accuracy or precise calibration as most of the testing is of a relative nature anyway, ie eliminating peaks and dips in the crossover performance.
Can anyone suggest a test setup (inc microphone)? I have contacted Bruel & Kjaer Sound and Vibration here in Australia but their basic system is $15,000 - a little out of my budget!
Thanks
