Peavey VR112 Manual De Usuario
Line curvature, or splay between cabinets
Splaying the line will tend to require more level increase from the tweeters, and some
more cut EQ at 1.8 kHz.
A uniform splay of 2.5 degrees between cabinets for an 8 cabinet array would need
approximately 2 dB of tweeter boost, and 0.5 dB of 12” woofer level increase, relative
to a subwoofer level. A uniform splay of 5 degrees per cabinet for an 8 cabinet array
would require approximately 5 dB of tweeter level boost, and approx. 1 dB of 12”
woofer level increase, relative to a subwoofer.

112: Woofer= 0.0 dB, Tweeter= +8.5 dB (for ribbons wired 16 ohms)
SPECIAL NOTE: Versarray

218 Sub is in 4 ohm mode (woofers paralleled).
If the Versarray

218 Sub woofers are driven separately, using an amp with the
same gain as all the other amps, then drive level does not increase.
