SoundQubed HDX Series 6.5" 2-Way Component Speaker Set

SoundQubed HDX Series 6.5" 2-Way Component Speaker Set — Pair | Glass Fiber Cone | Silk Dome Tweeter | 400W Passive Crossover

The SoundQubed HDX Series 6.5" 2-Way Component Speaker Set is a complete front-stage upgrade engineered for enthusiasts who want a direct-fit, high-performance component system that keeps up with the rest of the HDX lineup. Built around a 6.5" glass fiber cone woofer, a 1.94" silk dome neodymium tweeter, and a 400W passive crossover with tweeter attenuation and protection, the HDX 6.5" component set delivers coherent midrange, crisp highs, and a wide soundstage — all from a system designed to install in stock door and dash locations with confidence. Sold as a pair with grills included.

The 6.5" woofer features a glass fiber cone with a rubber surround, a 1" / 25.5mm KSV voice coil former wound with EISV winding material, and a 410g barium ferrite magnet in a black matte steel basket. With 50W RMS / 150W max power handling, 86 dB sensitivity, and a frequency response of 40 Hz–20 kHz, it delivers solid midrange output with a recommended hi-pass crossover at 60 Hz. The 1.94" silk dome tweeter uses a neodymium magnet and EISVM winding on an ASV 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, metal film capacitors, ASV coil, tweeter attenuation adjustment, and built-in tweeter protection.

Why Choose the SoundQubed HDX Series 6.5" Component Set?

• 50W RMS / 150W Max @ 4Ω — Handles real amplifier power for a component set in this class — pairs well with any SoundQubed 4-channel amplifier.
• Glass Fiber Cone + Rubber Surround — Stiff, lightweight cone material delivers accurate midrange with controlled resonance and long-term durability.
• 1.94" Silk Dome Neodymium Tweeter — Smooth, detailed high-frequency reproduction with a neodymium motor for high sensitivity in a compact package.
• 400W Passive Crossover @ 3.5 kHz / 12 dB/Oct — High-quality crossover with metal film capacitors, tweeter attenuation, and built-in tweeter protection — no active crossover required.
• 86 dB Sensitivity — Efficient enough for head unit power, but designed to shine with proper amplification.
• 40 Hz–20 kHz Frequency Response — Wide range from upper bass through extended treble — a complete front-stage solution.
• Stock-Location Friendly — 5.6" baffle cutout and 2.36" mounting depth fit most OEM 6.5" door and dash locations without modification.
• Grills Included — Complete install-ready package — woofer grills included for a clean, finished look.

Installation & Pairing Recommendations

Amplifier Pairing: The HDX 6.5" component set handles 50W RMS / 150W max at 4Ω. It pairs perfectly with any SoundQubed 4-channel amplifier — the Q4-150ABv2 (150W x4), Q4-2000 (325W x4), or Q4-3200 (520W x4) are all excellent matches. Run channels 1/2 for the front component set with the amplifier’s HPF set at 60–80 Hz, and let the passive crossover handle the woofer/tweeter split at 3.5 kHz.

Crossover Setup: The included passive crossover handles the 3.5 kHz woofer/tweeter split with a 12 dB/oct slope and tweeter attenuation adjustment. Connect your amplifier output to the crossover input (+W– for woofer, +T– for tweeter), then run the crossover outputs to the woofer and tweeter separately. Use the tweeter attenuation to balance the high-frequency level to your taste and room acoustics.

Woofer Mounting: The 6.5" woofer requires a 5.6" / 142mm baffle cutout and 2.36" / 60mm mounting depth. With grill, overall diameter is 7.26" and depth is 3". Verify door panel depth before installation — most OEM 6.5" locations will accommodate this driver without modification.

Frequently Asked Questions

Q: What amplifier should I pair with the HDX 6.5" component set?
A: The HDX 6.5" handles 50W RMS / 150W max at 4Ω. The SoundQubed Q4-150ABv2 (150W x4), Q4-2000 (325W x4), or Q4-3200 (520W x4) are all excellent matches. Set your amplifier’s 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 with this component set?
A: No — the HDX 6.5" component set includes a 400W passive crossover that handles the 3.5 kHz woofer/tweeter split with a 12 dB/oct slope, tweeter attenuation adjustment, and built-in tweeter protection. 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 2.36" / 60mm mounting depth. Most OEM 6.5" door locations will accommodate this driver without modification. Always verify your door panel depth before purchasing.

Q: What’s included in the set?
A: Each set includes a pair of 6.5" woofers with grills, a pair of 1.94" silk dome tweeters, and a pair of 2-way passive crossovers — everything you need for a complete front-stage component install.
