Bassnectar NYE 2016 analysis
« on: January 05, 2016, 05:56:53 am »

I got a question regarding Rat Sound Systems' subwoofer setup designed by Dave Rat for Bassnectar NYE 2016, so I thought I break it down.

DISCLAIMER: This analysis, in the interest of education, is based on a single photo and the physical dimensions of a single L-ACOUSTICS SB28 subwoofer. Dave Rat has disclosed it was gradient, but I've modeled both end-fire and gradient approaches. I did not design, install or operate this system and am not affiliated with either Rat Sound Systems or Bassnectar.

All physical dimensions point towards the use of SB28_60 (60 Hz bandwidth) presets.

Maximum cancellation in the center occurs around 40 Hz for End-Fire and "full-range" for gradient.

Normally I wouldn't recommend a 5 : 3 ratio because it noticeably compromises rear cancellation. However, IN THIS INSTANCE at CLOSE DISTANCE (4,75 m / 15.7 ft) the ratio accounts for the level difference introduced by the physical displacement between the rings (inverse square law).

Link to Soundvision files are below.

Enjoy!
