SoundQubed HDS Series 6.5" 2-Way Component Speaker Set — Paper Cone | Silk Dome Tweeter | 400W Passive Crossover | Pair
The SoundQubed HDS Series 6.5" 2-Way Component Speaker Set is SoundQubed’s entry-level component system — built for enthusiasts who want a meaningful upgrade over stock door speakers without breaking the bank. The HDS Series stands for Heavy Duty Street Series, and that’s exactly what you get: a speaker that handles more power, looks good, and fits your budget. Featuring a paper cone woofer, rubber surround, a 280g barium ferrite magnet, a 1.75" silk dome neodymium tweeter, and a 400W passive crossover, the HDS 6.5" component set delivers 50W RMS / 150W max at 86 dB sensitivity with a frequency response of 35 Hz–20 kHz. Sold as a pair with grills included.
The 6.5" woofer features a 1" / 25.5mm ASV voice coil former wound with EISV winding material, a paper cone with a rubber surround, and a black matte steel basket. The 1.75" / 45mm silk dome tweeter uses a neodymium magnet and EISVM winding on a KSV former for smooth, detailed high-frequency reproduction. The included 2-way passive crossover crosses over at 3.5 kHz with a 12 dB/oct slope, non-polar capacitors, KSV coil, screw terminals, and ABS housing. If you need more power and performance, step up to the SoundQubed HDX Series 6.5" 2-Way Component Set — the HDS is the smart starting point for a budget-conscious front stage upgrade.
Why Choose the SoundQubed HDS Series 6.5" Component Set?
- 50W RMS / 150W MAX @ 4Ω — Handles real amplifier power for an entry-level component set — a significant step up from stock speakers.

- 400W Passive Crossover @ 3.5 kHz / 12 dB/Oct — Quality crossover with non-polar capacitors, KSV coil, and screw terminals — no active crossover required.
- 35 Hz–20 kHz Frequency Response — Wide range from upper bass through extended treble — a complete front-stage solution.
- Grills Included — Complete install-ready package for a clean, finished look.
Installation & Pairing Recommendations
Amplifier Pairing: The HDS 6.5" component set handles 50W RMS / 150W max at 4Ω. It pairs well with any SoundQubed 4-channel amplifier — the S4-100 (100W x4) is an ideal match for a budget-friendly daily driver build. Set your amplifier’s HPF at 60–80 Hz and let the passive crossover handle the 3.5 kHz woofer/tweeter split.
Crossover Setup: Connect your amplifier output to the crossover input, then run separate leads from the crossover to the woofer (+W–) and tweeter (+TW–). The 3.5 kHz / 12 dB/oct passive crossover handles the woofer/tweeter split automatically. See the wiring diagram below for reference.
Woofer Mounting: The 6.5" woofer requires a 5.6" / 142mm baffle cutout and 2.24" / 57mm mounting depth. With grill, overall diameter is 7.28" / 185mm. Verify your door panel depth before installation.
Upgrade Path: If you need more power handling and performance, the SoundQubed HDX Series 6.5" 2-Way Component Set is the next step up — featuring a glass fiber cone, higher power handling, and metal film capacitors in the crossover.

Frequently Asked Questions
Q: What’s the difference between the HDS and HDX component sets?
A: The HDS is SoundQubed’s entry-level component set — paper cone, 50W RMS, and a natural, musical character. The HDX steps up to a glass fiber cone, higher power handling (50W RMS with metal film capacitors in the crossover), and is designed for builds that need more output and durability. Both use the same 3.5 kHz passive crossover point.
Q: What amplifier should I pair with the HDS 6.5" component set?
A: The HDS handles 50W RMS / 150W max at 4Ω. The SoundQubed S4-100 (100W x4) is a perfect match for a daily driver build. Set your HPF at 60–80 Hz and let the passive crossover handle the 3.5 kHz woofer/tweeter split.
Q: Do I need an active crossover or DSP?
A: No — the HDS 6.5" component set includes a 400W passive crossover that handles the 3.5 kHz woofer/tweeter split with a 12 dB/oct slope. Connect your amplifier output to the crossover, then run separate leads to the woofer and tweeter.
Q: Will the 6.5" woofer fit my OEM door location?
A: The woofer requires a 5.6" / 142mm baffle cutout and 2.24" / 57mm mounting depth. Most OEM 6.5" door locations will accommodate this driver without modification. Always verify your door panel depth before purchasing.
