• 103.5 dB sensitivity: This high sensitivity means the tweeters can produce strong output with comparatively little amplifier power.
• 8 oz ferrite motor: The ferrite motor supplies magnetic force for the tweeter’s high-sensitivity design.
• CCAW voice coil on a Kapton former: This lightweight winding and former combination supports sustained high-power use.

Technical Specifications

Why Choose This Product?

The HDS-PAT1 is built for car audio setups that call for dedicated high-frequency output from a compression tweeter. Its stated 3.5 kHz–20 kHz response and 103.5 dB sensitivity suit systems where treble output needs to be considered alongside the levels of the other speakers.

For a two-way active front stage, the product details identify the SoundQubed PA6B-4 and PA65M-8 6.5-inch pro audio midranges as pairing options. The machined faceplate and Q logo also make the tweeter’s appearance part of the installation.

Installation & Compatibility Notes

The HDS-PAT1 has no built-in bass blocker. Use an active crossover or DSP with a 3.5 kHz high-pass filter, or a passive crossover set to 3.5 kHz. Do not run the tweeter full-range.

Its sensitivity is 103.5 dB, so its output may be significantly louder than that of many woofers at the same power level. The product guidance recommends a separate amplifier channel or level adjustment through a DSP or crossover. For the named two-way midrange pairing, set the midrange low-pass and tweeter high-pass at 3.5 kHz; use a DSP for level matching.

Allow for the 2.83-inch / 72mm front baffle cutout and 2.56-inch / 65mm mounting depth. Check the installation location for clearance, including the 2.78-inch / 70.5mm overall depth.
