Description

Product Overview

Bring separate woofers and tweeters to your front stage with the SoundQubed HDX Series 6.5" 2-Way Component Speaker Set. Its glass fiber woofers, silk dome tweeters, and included passive crossovers provide a dedicated speaker system for your vehicle’s audio setup.

Each set is sold as a pair and includes woofer grilles. The crossover provides a 3.5 kHz woofer-to-tweeter split, tweeter attenuation, and built-in tweeter protection.

Key Features & Benefits

Glass fiber woofer cone: Paired with a rubber surround for the specified woofer construction.
Silk dome tweeter: The 1.94" tweeter uses a neodymium magnet and silk diaphragm.
Passive crossover: A 12 dB/oct slope and 3.5 kHz crossover point divide the woofer and tweeter signals.
Tweeter adjustment: Attenuation lets you adjust the tweeter level.
Woofer grilles included: The set includes grilles for the pair of woofers.

Why Choose This Product?

This component set separates the woofer and tweeter, with the included passive crossover managing their 3.5 kHz split. Its tweeter attenuation adjustment gives you a way to balance the high-frequency level to your taste and room acoustics.

The woofer’s 50W RMS and 150W maximum ratings, 4-ohm impedance, and 86 dB sensitivity help inform amplifier selection. The set’s 40 Hz–20 kHz frequency response and recommended 60 Hz hi-pass crossover provide additional reference points when planning your system.

Installation & Compatibility Notes

Check available mounting space before installation. The woofer requires a 5.6" / 142mm baffle cutout and 2.36" / 60mm mounting depth; with its grille, overall depth is 3" / 76.5mm. The tweeter requires a 1.9" / 48.4mm cutout and 0.82" / 21mm mounting depth.

Connect the amplifier output to the passive crossover, then run separate leads from the crossover to the woofer and tweeter. The crossover handles the 3.5 kHz split; the source recommends an amplifier hi-pass setting of 60–80 Hz. Suggested amplifier models in the product information are the SoundQubed Q4-150ABv2 (150W x4), Q4-2000 (325W x4), and Q4-3200 (520W x4). Radio, amplifier, wires, and battery are not included.
