HND31-99 — 4" Voice Coil Compression Driver For Stage Performance
The HND31-99 is a bolt-on compression driver with a 99 mm (4 inch) voice coil in the GRANVOZ catalogue, intended for stage and horn loudspeaker systems. The manufacturer documents this model with a published product description rather than a separate specification table, so this page presents that description in full and does not re-format it as a parameter table.

The text above is the manufacturer's own published product description for the HND31-99, reproduced exactly as published — including its parameter wording — because no separate specification table is published for this model. Read it as the manufacturer's document, and ask the sales team to confirm any figure you plan to design against before you rely on it in an enclosure, crossover or amplifier pairing.
Where this model fits
Within the catalogue, the HND31-99 sits at the high-output end of its family. Models like this are normally shortlisted by system builders who start from the application — stage and horn loudspeaker systems — and then confirm the electrical and mechanical details with the factory. If your programme needs a fully tabulated alternative in the same family, the related models below include the family's fully specified pages; otherwise, treat the description above plus a written confirmation from the sales team as your specification source for this model.
Ordering notes
The manufacturer publishes no model-specific FAQ terms for the HND31-99. For OEM branding, the manufacturer's published general levels are a 200-piece order for logo application on the dust cap, paper cone, basket or magnet, and a 500-piece order for OEM boxes. Ask the sales team to confirm, in the written quotation for this exact model: the minimum order quantity, the rated power and impedance as you will order them, the packing specification, and the lead time — the company describes its lead times as short but publishes no fixed figure. Ask also for the Thiele-Small parameter set if your enclosure design depends on it; the company states that its acoustic sound testing provides Thiele-Small parameters for its speakers.
- Confirm the impedance configuration of the unit as ordered, in writing.
- Confirm sample terms for your first order before committing to a production quantity.
- Confirm warranty and after-sales terms for the model in writing before payment.
