Waves Sub Align

This plugin lets FOH engineers align subwoofer and top speakers in PA systems where the subs are tied in with the tops and the system processor is inaccessible.

Compact, portable PAs with separate subs and tops are great for musicians playing small venues—except in clubs that position subs and tops based on physical convenience, not sound quality. When subs and tops aren’t aligned correctly, the bass becomes muddy, weak, and indistinct.

Sub Align inserts in your master bus, and “moves” the subs virtually in relation to the tops. Once you hear the difference that proper alignment makes, you’ll never gig without Sub Align again.

Why Alignment Matters

Ideally, the PA’s top is right above the sub. But if the sub is placed elsewhere, phase misalignment can degrade sound quality. Sub Align delays or advances the sub virtually, for proper phase alignment and better sound.

Work With the PA, not Against It

Sub Align’s crossover control lets you match the PA system’s internal crossover frequency. This ensures that the correct low-end frequencies are going to the subs for proper alignment.

Easy Interface

The straightforward interface (which is also touch-friendly) makes it easy to align the sound, whether mono or stereo. Link stereo channels or adjust them independently, solo subs or tops, and tweak gain as well as phase.
