Making A Splay: A Simple Asymmetric Coupled Point Source Loudspeaker Calculator
Loudspeakers coupled as tightly as possible with a ratchet strap might be structurally sound, but isn’t an optimum electroacoustic approach.
By Michael Reed • February 7, 2019

One thing I see frequently in live sound reinforcement is the classic configuration of two main loudspeakers per side, coupled as tightly as possible with a ratchet strap.

While structurally sound, this isn’t an optimum electroacoustic approach.

The cabinet edges of a loudspeaker usually have nothing to do with the horizontal dispersion angle, and for most models, coupling along the edges and driving both sources at the same gain results in a horrible, comb-filtered mess, with some summation...
