Buyer research

Questions buyers ask about the Ballista

Common pre-purchase questions on the HSD Ballista.

Q1

What amplification does a Ballista hang need?

Each module is a four-way passive design, LF (2,600 W), MF (800 W), HM (180 W), and HF (100 W) sections at 8 ohms each, wired through dual NL8 connectors. The straightforward plan is one four-channel HSD KP Series or KD Series amplifier per module with HSD FIR presets. On larger hangs, sections can share channels across modules, send us your module count and we will build the amp schedule.

Q2

How does the Ballista fly and ground-stack?

Integrated flyware is built in. The MH-24 main hanger ($3,850) supports up to 24 modules per side for flown arrays; the BC-3 cart ($2,200) carries three modules for fast truck packs and doubles as the ground-stack base; padded covers ($950) protect module and cart in transit. All three are in the additional products table.

Q3

What subs go under a Ballista rig?

The module holds -3 dB to 60 Hz with dual 12s and phenomenal mid-bass clarity, so it wants serious sub-bass below it: Battlehawk or BattleAxe ground stacks for touring, or Sherman bases when the show calls for the flagship.

Q4

Why choose the Ballista over a big point-source rig?

Coverage consistency over distance. A hung line of Ballistas controls vertical dispersion so front rows and back rows get the same mix, the physics that point sources cannot replicate past a certain room depth. With 115 dB HF sensitivity and four-way passive convenience, it is HSD's affordable route into true large-format line array.

This pairs well with
