Back chamber effect (Oris Horns)

by Rudy81 @, Dallas, TX, Thursday, February 21, 2013, 21:37 (1760 days ago)

While setting my new Oris 150s up today I decided to see if there was any measurable effect on response with the chamber cover removed vs. installed. I believe Bert indicated that LF would be enhanced with the back installed. Here are my results with the Tang Band 1800 driver, calibrated mic and soundcard, using REW 5.

BTW, the crossover is set up to cross at 153Hz, so you see an early roll off due to the crossover.

The green line is the back cover installed.

Bert, Thank you for all your help. I have not finished the setup, but thus far these are everything I wanted!
