SoundQubed HDX-CX57 — 5x7" 2-Way Coaxial Speakers | Glass Fiber Cone | Neodymium Tweeter | Pair
The SoundQubed HDX-CX57 is a high-performance 5x7" 2-way coaxial speaker built for enthusiasts who want a direct-fit, stock-location upgrade that keeps up with the rest of the HDX lineup. Featuring a glass fiber cone, rubber surround, a 410g barium ferrite magnet, and an integrated neodymium PEI dome tweeter, the HDX-CX57 delivers 70W RMS / 210W max at 91 dB sensitivity with a frequency response of 40 Hz–20 kHz. Sized to fit standard 5x7" factory mounting locations, it’s the straightforward, high-performance upgrade your front stage deserves. Sold as a pair with grills included.
The HDX-CX57 woofer features a 1" / 25.5mm KSV voice coil former wound with EISV winding material, a glass fiber cone with a rubber surround, and a matte black steel basket. The integrated 1" / 25.5mm neodymium tweeter uses a PEI diaphragm and EISVM winding on a KSV former for smooth, detailed high-frequency reproduction. With a recommended hi-pass crossover at 60 Hz, the HDX-CX57 works seamlessly with your amplifier’s built-in crossover — no separate passive crossover required.
The T/S parameters confirm a well-engineered driver: Fs of 68 Hz, Xmax of 2.7mm, Vas of 8.66L, and a cone area (Sd) of 153.5cm². Whether you’re building a daily driver system or upgrading a factory front stage to match an HDX subwoofer, the HDX-CX57 delivers the output and clarity to complete the picture.
Why Choose the SoundQubed HDX-CX57?
- 70W RMS / 210W MAX @ 4Ω — Handles real amplifier power for a 5x7" coaxial — pairs well with any SoundQubed 4-channel amplifier.
- 91 dB Sensitivity (1W/1m) — High efficiency means more output per watt — loud and clear even with modest amplification.
- Glass Fiber Cone + Rubber Surround — Stiff, lightweight cone material delivers accurate midrange with controlled resonance and long-term durability.
- 410g Barium Ferrite Magnet — Powerful motor for a 5x7" coaxial — drives the cone with authority for solid midbass output.
- Neodymium Tweeter (PEI Diaphragm) — Smooth, detailed high-frequency reproduction integrated directly into the coaxial design — no separate tweeter install required.
- 40 Hz–20 kHz Frequency Response — Wide range from upper bass through extended treble — a complete front-stage solution in a single driver.
- Direct-Fit 5x7" Footprint — 4.9" x 7" / 125 x 179.5mm baffle cutout fits most OEM 5x7" door and dash locations without modification.
- Grills Included — Complete install-ready package for a clean, finished look.
Installation & Pairing Recommendations
Amplifier Pairing: The HDX-CX57 handles 70W RMS / 210W max at 4Ω. It pairs perfectly with any SoundQubed 4-channel amplifier — the Q4-150ABv2 (150W x4), Q4-2000 (325W x4), or S4-100 (100W x4) are all excellent matches. Set your amplifier’s HPF at 60–80 Hz to protect the driver and maximize output.
System Integration: The HDX-CX57 is engineered to pair with HDX subwoofers for a coordinated, full-range system within the same lineup. Run the HDX-CX57 on your front channels (HPF at 60–80 Hz) and let a dedicated SoundQubed monoblock handle the low end for a complete, balanced build.
Mounting: The HDX-CX57 requires a 4.9" x 7" / 125 x 179.5mm baffle cutout and 2.3" / 58.5mm mounting depth. Without grill, overall dimensions are 5.5" x 8.6" / 140 x 220mm. With grill: 6" x 8.9" / 154 x 226mm. Verify your door panel depth before purchasing.
