Back chamber effect (Oris Horns)

Your comments have really piqued my interest in finding out what the horn alone can really do. I am going to bring one down from my listening room and take it outside to try and get a semi-anechoic measurement.

You say you run the 150 full range. Does that not stress your driver when trying to go well below 100Hz or so? I am curious as to what the driver can really handle. In terms of the Tang Band, the manufacturer says it is capable of 45Hz to 20kHz. I plan on running my test from 45Hz to 20kHz. I will be using my Behringer calibrated mic, although it is not an expensive piece, it should give us a reasonable response. The Tascam audio card will be attached to my laptop via USB and REW will interpret the results.

I will post the results later today.
