Buyer research

Questions buyers ask about the Mantarray 90

Common pre-purchase questions on the HSD Mantarray 90.

How is the Mantarray 90 different from the Mantarray 60?

Two things: coverage and reach. The 90 throws a 90 × 40-degree pattern for wide rooms and shorter throws, and its low-frequency response extends to 90 Hz (-3 dB) / 75 Hz (-10 dB), deep enough to cross straight into subwoofers without a dedicated mid-bass layer. The Mantarray 60 trades width for array behavior and longer throw.

What amplifier drives the Mantarray 90?

Two channels per cabinet: LF 800 W and HF 100 W continuous, both 8 ohms nominal. A four-channel HSD KP Series amp runs a stereo pair of Mantarray 90s with HSD FIR presets per channel.

How does it rig?

Sixteen M10 fly points are built into the cabinet, with optional L-track or flybar accessories for flown deployments. At 100 lbs it also ground-stacks cleanly on subs for installs and pop-up stages.

What subs pair with the Mantarray 90?

Because it holds -3 dB to 90 Hz, it crosses directly into HSD's FLH subs. The Switchback or Eagle 18s suit compact rigs; the Tomahawk and BattleAxe 21s bring festival-scale weight underneath.
