SoundQubed SQ-HDX-2HDT-8 6" Aluminum Horn + 2" Titanium Driver (each)

Product Overview

Bring high output and wide sound coverage to your car audio front stage with the SoundQubed SQ-HDX-2HDT-8 6-inch aluminum horn and 2-inch titanium compression driver. Its 114 dB sensitivity with horn, 57° rounded coverage, and 900 Hz recommended high-pass crossover suit systems designed for strong output across a broad listening area.

Key Features & Benefits

• 114 dB sensitivity with horn: The stated sensitivity helps you assess output when planning system levels.
• Titanium diaphragm: The diaphragm material is specified for high-frequency reproduction.
• 2-inch voice coil: The large-format coil is paired with a Kapton former and CCAW winding.
• Aluminum short horn: The 6-inch horn provides a 57° rounded sound coverage pattern.
• 900 Hz recommended high-pass: This crossover point allows the driver to cover frequencies below the range of many compression tweeters.
• Sold individually: Order two units if you need a pair.

Why Choose This Product?

The SQ-HDX-2HDT-8 combines a titanium diaphragm, ferrite motor, and aluminum horn in one driver system. Its 57° rounded coverage is wider than the 35° pattern stated for the SQ-HDC-1HDP-8. The 2HDT-8 is also specified with 114 dB sensitivity, 320W RMS power handling, and a 900 Hz recommended high-pass crossover; the comparison model is listed at 108 dB, 120W RMS, and 2 kHz.

That lower crossover point can let the horn cover upper midbass through treble in some active two-way or three-way systems. Use a DSP or active crossover to manage crossover points and balance its level with the rest of your system.

Installation & Compatibility Notes

• Crossover: Use an active crossover or DSP with a 900 Hz high-pass filter minimum. Do not run the driver full-range. For competition builds, the source recommends a 900 Hz high-pass and 15–20 kHz low-pass band-pass configuration.
• Amplifier: Check the amplifier’s power rating at 8 ohms before purchase. Use per-channel level control and attenuation as needed to balance the horn with other speakers.
• Impedance: One unit is 8 ohms. Two units wired in parallel present a 4-ohm load; check the amplifier’s minimum impedance rating first.
• Mounting: Check the mounting hole, bolt pattern, and 5.83-inch mounting depth against your available space before installation.

Frequently Asked Questions

Is the SQ-HDX-2HDT-8 sold as a pair?

No. It is sold as a single unit; order two for a stereo pair.

What does the 114 dB sensitivity rating describe?

The stated 114 dB sensitivity is measured at 1W/1m with the horn attached.

Can this driver cover part of the midrange range?

Its frequency response is 630 Hz–20 kHz, with a recommended 900 Hz high-pass crossover. The supplied details describe use in some active two-way or three-way systems. Set crossover points with a DSP or active crossover.

What amplifier load should I plan for?

Each unit has an 8-ohm nominal impedance. Two units wired in parallel present a 4-ohm load, so confirm your amplifier supports the resulting load.

Will it fit my mounting location?

Compare the 5.75-inch mounting hole, 6.33-inch bolt pattern, and 5.83-inch mounting depth with your installation space.
