SP Audio SP-8CX Midrange 8″ / 20 cm – 150 W RMS (Pair) Super-Slim

The SP Audio SP-8CX pair represents the culmination of an 8″ (20 cm) “Super-Slim” midrange designed for car audio enthusiasts. With only 150 W RMS (and a manufacturer’s datasheet that can go beyond), this model combines installation finesse with sound performance.

Thanks to its ultra-flat format and meticulous design, this midrange integrates easily into vehicles with limited space while delivering exceptional mid-range / upper-midrange reproduction: vocal clarity, nuanced instruments, controlled dynamics – everything you expect from a high-end audio system.

Technical specifications

• Format: 8″ / 20 cm (nominal diameter)
• Nominal power (RMS): 150 W (pair) — “super-slim” model
• Nominal impedance: 4 Ω (typically)
• Ultra-flat profile for easy mounting in compact or demanding vehicles
• Robust connectors, high-performance voice coil, dedicated upper-midrange cone

Why choose this SP-8CX pair?

Because you are looking for:

• A large midrange speaker (20 cm) capable of "breathing" and being freer than a 16.5 cm model
• A "Super-Slim" format that easily adapts to shallow or premium locations
• A more open, more present sound, with a clear midrange, without bloating or excess
• A system that remains discreet but highly efficient in a vehicle where space is limited

Recommended applications

• Replacement of original speakers in vehicles with 20 cm slots
• High-end 2-way or 3-way audio systems where well-defined mids and upper mids are desired
• Installations in compact vehicles or those with limited depth (doors, ceilings, arches, etc.) where a "slim" model is an asset
• In combination with a high-end tweeter and a subwoofer, for balanced and precise rendering

Installation tips

To fully utilize this SP-8CX pair:

• Allow for a compatible 200 mm (20 cm) cutout and check available depth
• Use an appropriate high-pass filter (e.g., 80-120 Hz) if the midrange shares the bass with a woofer
• Install with a solid mounting and ideally a rigid baffle for optimal performance
• Choose quality amplification (at least 100 W RMS per speaker) to express its dynamics

Pack contents
