Two catalogue listings for the HST105-1B
The manufacturer's catalogue lists the HST105-1B twice. This page covers the listing titled “1 Inch Voice Coil High Performance Tweeters”. A second listing, titled “1 Inch Voice Coil Tweeter Speaker 4 Ohm”, publishes an identical specification table and the same product description. The two listings are kept as separate pages on this site so each catalogue entry can be quoted against its own title; ask the sales team to confirm which listing your quotation refers to, so the order paperwork matches the entry you selected.
Where this model fits
The HST105-1B listing on this page is the one the manufacturer titles for high performance, and its published table supports that positioning: a titanium diaphragm on a 25.4 mm KSV voice coil, a 70 × 32 × 15 mm magnet, 25 W RMS rated power and 99 dB sensitivity across a published 1.5 kHz–20 kHz response. In programme terms, this is the tweeter tier for high-output car builds and pro-style doors, where the top end must keep up with high-sensitivity midrange drivers rather than with factory head-unit speakers.
Pair it by the figures: a midrange publishing around 99–100 dB sensitivity (the MD-65S23-06 class) meets this tweeter at a workable crossover level without heavy padding, and its 97 × 87 mm housing (as dimensioned in the published table) needs a cutout check in shallow door cards. Ask the sales team for the model's Thiele-Small data only if your crossover design workflow requires it; for a tweeter of this class, the published table plus a sample pair covers most programme decisions.
Ordering notes
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.
