Frequency Response Charts

thoburnse40 · 30th October 2007, 09:55 PM

This is a newbee question for Panet10 or ScottMoose and I really have tried to search for the this. I have noticed that your frequency response charts only go to 1000Hz. Why is that?

Thanks.

The reason they only go to that point is that the BW of a back-loaded cabinet is relatively narrow; above ~1KHz, the cabinet ceases to have any real effect on the response. Above that point, the driver response will be essentially as per it's IB plot. Heavily simplified of course, but it basically holds good, so the MathCad graphs stop at that frequency.

Thanks Scott.

I thought that was why, but was not sure
