Where this model fits
The HDN-30-44 belongs to the super tweeters family — the top end of a car audio or PA system, reproducing the highest frequencies the rest of the system cannot cover. It is one of the models in that family for which the manufacturer publishes a complete specification table, which is why it has its own page here: buyers comparing drivers for an OEM programme or a wholesale range can work from documented figures instead of a catalogue title alone.
Compare this model against the other fully specified models in the family (linked below), and treat the published table as the reference document: if a figure you need is not in the table — mounting depth drawings, for example, or Thiele-Small parameters — ask the sales team for it. The company states that its acoustic sound testing provides Thiele-Small parameters for its speakers, so ask for the parameter set for this model if your enclosure design depends on it.
Ordering notes
The manufacturer's published product FAQ for this model states an MOQ of 500 pieces with an OEM box and 200 pieces without one. Treat that as this model's own published term — minimum order quantities differ across the catalogue — and ask the sales team to confirm it still applies when you request the quotation.
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; the model-specific FAQ term above takes precedence where one is published. Ask the sales team to confirm, in the written quotation for this exact model: the applicable MOQ with your packaging choice, the final specification against the table on this page, the packing quantity, and the lead time for your order — the company describes its lead times as short but publishes no fixed figure.
- Confirm the impedance variant you need where the table lists more than one nominal impedance.
- Confirm the sample process: the manufacturer's product FAQs describe samples as offered for testing once an order is confirmed — ask how that applies to your first order.
- Confirm warranty and after-sales terms for the model in writing before payment.
