SoundQubed HDS Series 5x7" Coaxial 2-way Speakers (Pair)

SoundQubed HDS Series 5x7" 2-Way Coaxial Speakers — Paper Cone | Mylar Dome Tweeter | Pair

The SoundQubed HDS Series 5x7" 2-Way Coaxial is SoundQubed’s entry-level 5x7" coaxial speaker — built for enthusiasts who want a meaningful upgrade over stock door and dash 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, rubber surround, a 226g barium ferrite magnet, and an integrated 1" Mylar dome neodymium tweeter, the HDS 5x7" delivers 50W RMS / 150W max at 85 dB sensitivity with a frequency response of 78 Hz–20 kHz. Sold as a pair. No grill included. If you need more power and performance, step up to the SoundQubed HDX-CX57 — the HDS is the smart starting point for a budget-conscious 5x7" upgrade.

The HDS 5x7" 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 integrated 1" / 25.4mm Mylar dome tweeter uses a neodymium magnet (3g) and EISVM winding on a KSV former for high-frequency reproduction. With a recommended hi-pass crossover at 90 Hz, the HDS 5x7" works seamlessly with your amplifier’s built-in crossover — no separate passive crossover required.

The T/S parameters confirm a solid entry-level driver: Fs of 76 Hz, Xmax of 2.7mm, Vas of 6.7L, and a cone area (Sd) of 55cm². Whether you’re upgrading factory 5x7" door or dash locations, the HDS 5x7" delivers the output and value to get it done.

Installation & Pairing Recommendations

Amplifier Pairing: The HDS 5x7" 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 90 Hz to protect the driver and maximize output.

Upgrade Path: If you need more power handling and performance, the SoundQubed HDX-CX57 (70W RMS / 210W max, 91 dB, glass fiber cone, neodymium PEI tweeter) is the next step up in the 5x7" lineup.

Mounting: The HDS 5x7" requires a 4.9" x 7" / 126 x 180mm baffle cutout and 2.1" / 53.5mm mounting depth. Overall dimensions are 5.5" x 8.6" / 140 x 220mm, overall depth is 2.48" / 63mm. No grill included — plan your mounting location accordingly. Verify your door panel depth before purchasing.
