RSS-603 Reverberation Room Testing Speakers

April 29, 2016 Leave a comment

This set of speakers were designed as reference source speakers for testing in reverberation chamber. To be suitable for this condition the set of six speakers need to be able to reach a high sound pressure level with a frequency response of +/- 3dB per ANSI standards. Additionally, due the sound pressure needed at a constant duration, the drivers needed high power handling capabilities. The specific room that these will be installed do not accurately test below 400 Hz so this was taken into consideration in the design.

Tech Specs:

-F3 of 250 Hz

+/- 2.25 dB

Two way digital cross over

Mono for testing capabilities

Drivers:

Woofer: Celestion NTR06-1705B 6-1/2″

Tweeter: Tymphany D27TG35-0
