Why Choose This Product?

The PA6B-4 is a dedicated pro audio midrange driver, not a full-range speaker. Its listed 80 Hz–12 kHz frequency response and 160 Hz recommended high-pass crossover help define its role when you plan a two-way or three-way active front stage.

Its 1.5-inch CCAW voice coil uses a Kapton former, while the speaker combines a cloth surround with a steel basket. These construction details help you compare it with other midrange options for your build.

Installation & Compatibility Notes

Use a high-pass crossover set at 160 Hz minimum. A band-pass configuration with a 160 Hz high-pass and an 8–12 kHz low-pass is recommended in the product details. An active crossover or DSP can manage crossover points.

The speaker handles 150W RMS at 4 Ohms. The SoundQubed S4-100 (100W x4) and Q4-150ABv2 (150W x4) are listed as amplifier pairing options. For a complete system, pair this dedicated midrange with a dedicated tweeter and a subwoofer or midbass driver.

Check the installation location against the 5.65" / 143.5mm baffle cutout and 2.4" / 61mm mounting depth. Allow for the listed 4.33" / 110mm motor diameter as you assess clearance.

Frequently Asked Questions

Is the HDS PA6B-4 sold as a pair?

No. Each order is for one speaker; order quantity two for a stereo pair.

What crossover setting is recommended?

The recommended high-pass crossover is 160 Hz. The product details also recommend a band-pass setup with an 8–12 kHz low-pass point.

What amplifier rating should I consider?

The speaker is rated at 150W RMS and 4 Ohms. The listed pairing options are the SoundQubed S4-100 (100W x4) and Q4-150ABv2 (150W x4).

What mounting space does it need?

Plan for a 5.65" / 143.5mm front-mount baffle cutout and 2.4" / 61mm mounting depth. Overall diameter is 6.55" / 166.4mm, and overall depth is 2.66" / 67.6mm.

How does it differ from the SoundQubed PA6B-4?

The HDS PA6B-4 is rated at 150W RMS and uses a 23 oz ferrite motor, steel basket, and Kapton former. The separate SoundQubed PA6B-4 is listed at 300W RMS, with a 30 + 3 oz ferrite and neodymium hybrid motor, aluminum basket, and glass fiber former.
