Description

Product Overview

Give your car’s front stage a separate woofer and tweeter with the SoundQubed HDS Series 6.5-inch 2-way component speakers. The pair combines a paper-cone woofer, silk-dome neodymium tweeter, and included passive crossovers for a component-speaker upgrade rated at 50W RMS per set.

With a 4-ohm impedance and 86 dB sensitivity, the HDS set is designed for use with a head unit or amplifier. Grilles are included for a finished speaker installation.

Key Features & Benefits

Paper cone and rubber surround: The 6.5-inch woofer uses these materials for a natural midrange character.
Silk-dome tweeter: A 1.75-inch neodymium tweeter handles high frequencies separately from the woofer.
Passive crossover included: The 2-way crossover divides the signal at 3.5 kHz, so an active crossover is not required for the woofer-and-tweeter split.
50W RMS power handling: The speakers are rated for 50W RMS and 150W maximum at 4 ohms.
Grilles included: The pair includes grilles for a clean, finished appearance.

Why Choose This Product?

The HDS set is SoundQubed’s entry-level 6.5-inch component system. Its separate woofer and tweeter give you a two-way front-stage setup, while the included passive crossover manages their 3.5 kHz division. The paper cone and silk dome pair a natural midrange character with a dedicated tweeter for high frequencies.

The 50W RMS rating and 4-ohm impedance are key considerations when matching the speakers to your audio system. The supplied product details also recommend the SoundQubed S4-100 amplifier, rated at 100W x4.

Installation & Compatibility Notes

Check the woofer’s 5.6" / 142mm baffle cutout and 2.24" / 57mm mounting depth against your installation location. Allow for the stated 7.28" / 185mm overall diameter with the grille and 3.4" / 88.4mm overall depth with the grille. The tweeter requires a 2" / 51.6mm front-mount cutout and 0.8" / 20.5mm mounting depth. Check available space for the crossover, which measures 2.59" x 4.7" x 1.31".

Connect the amplifier output to the passive crossover, then run separate leads from the crossover to the woofer and tweeter terminals (+W– and +TW–). The crossover handles the 3.5 kHz split at a 12 dB/oct slope; an active crossover is not required for that function. The installation guidance suggests an amplifier high-pass filter setting of 60–80 Hz, while the specifications list a recommended hi-pass crossover of 60 Hz.

Radio, amplifier, wires, and battery are not included.

Frequently Asked Questions

What are the power and impedance ratings?

The set is rated at 50W RMS and 150W maximum at 4 ohms. Match your amplifier to the RMS rating and the system’s impedance.

Do I need an active crossover or DSP?

No active crossover is needed for the woofer-and-tweeter split. The included passive crossover handles the 3.5 kHz crossover point with a 12 dB/oct slope.

What mounting space should I check?

The woofer needs a 5.6" / 142mm baffle cutout and 2.24" / 57mm mounting depth. Check the tweeter and crossover dimensions above against your available locations, too.
