Buyer research

Questions buyers ask about the Sherman

Common pre-purchase questions on the HSD Sherman.

Is one Sherman really worth two BattleAxes?

That is HSD's own equivalence, and the math tracks: a 24″ driver on a 72″-deep horn with 108 dB sensitivity moves the air of two separate 21″ cabinets. One Sherman ($10,600) versus two BattleAxes ($14,200) is also the cheaper path to the same output, if your truck, stage, and crew can handle a 440 lb cabinet.

What amplifier drives the Sherman?

2,300 W continuous (4,600 W program), with a 4- or 8-ohm driver option. With the 4-ohm driver, one channel of the HSD KP Series 4-10KP or KD Series 4-10KD (2,500 W into 4 ohms) per Sherman is the clean match, four Shermans per 2U amp. The 8-ohm option suits parallel wiring schemes on high-power KD channels; we will spec it with you.

Who actually buys the Sherman?

Festival producers, outdoor event operators, and venues that program earth-moving low end as a feature, the events where the sub wall is part of the draw. It is the largest subwoofer HSD builds, and it exists for shows where nothing smaller is honest.

What are the logistics?

Plan seriously: 30″ W × 48″ H × 72″ D and 440 lbs per cabinet. It ships crated freight, wants a liftgate or forklift, and moves on wheels and ramps, not hands. We quote freight to your dock as part of every Sherman system.
