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

DG01 Near-Field Multipurpose Monitors

DG01 Wireframe

DG01 NEAR-FIELD MONITORS
The DG01 speakers are multipurpose mixing and listening speakers designed for near-field use. Despite their size, these desktop speakers were made to be listened to from a distance of only about a foot away.
To achieve the low end necessary for critical listening, the DG01s are designed as a ported box with a 2” port on the rear side. While this causes some loss of transient accuracy, it is more than made up for by the low-frequency extension. These speakers manage to reach an F3 of 38Hz while also boasting a +/- 3dB range from ~40Hz-19kHz. The range is possible due to the excellent drivers selected for the job—Dayton Audio RS225-8 for the woofers and SB Acoustics SB26STAC-C000-4 for the tweeters. With the use of a MiniDSP PWR-ICE125 amplifier and DSP unit for each monitor, a fairly flat response is easily achieved. With the design comes a very strong center image and a large sound stage.

QUICK FACTS:
Crossover: 4th-order, woofer at 2.2kHz, tweeter at 2kHz
Response: +/-3dB ~40Hz-19kHz
F3: 38Hz
Total cost (w/o MiniDSP): ~$400
Box materials: 1/2” MDF with 3/4” birch plywood
Size: 19”Hx15”Wx18”D
Tweeter: SB Acoustics SB26STAC-C000-4
Woofer: Dayton Audio RS225-8
