SoundQubed HDX Series Pro Audio 8" Speaker (each)

SoundQubed PA8M-8 — 8" Pro Audio Midrange | 350W RMS | 98 dB | Ferrite + Neodymium Hybrid Motor | 8Ω | Sold Single

The SoundQubed PA8M-8 is a purpose-built 8" pro audio midrange driver engineered for competition car audio, high-output daily drivers, and any build where maximum midbass and midrange output is the priority. Featuring a non-pressed paper cone, cloth surround, a ferrite + neodymium hybrid magnet system (30 + 3 oz), a 1.5" / 38.6mm CCAW voice coil on a glass fiber former, and an aluminum basket, the PA8M-8 delivers 350W RMS / 700W max at 98 dB sensitivity with a frequency response of 80 Hz–8 kHz at 8Ω. Sold as a single speaker — order the quantity you need for your build.

The PA8M-8’s ferrite + neodymium hybrid motor (30 + 3 oz) combines the high-flux density of neodymium with the thermal mass of ferrite — delivering exceptional sensitivity and sustained high-power performance without thermal compression. The 7.6mm one-way Xmax gives this driver serious linear excursion capability for an 8" midrange, allowing it to move real air at high output levels without distortion. With a Qts of 0.784 and Fs of 128 Hz, the PA8M-8 is optimized for use with a high-pass crossover at 125 Hz — keeping it in its optimal midbass and midrange operating range. The CCAW winding on a glass fiber former delivers lightweight, thermally efficient performance for sustained high-power use.

Sitting between the PA6B-4 (6.5", 300W RMS, 4Ω) and the PA10M-8 (10", 500W RMS, 8Ω), the PA8M-8 is the mid-size option in SoundQubed’s pro audio midrange lineup — delivering 8" cone area and 98 dB sensitivity in an 8Ω configuration ideal for high-power pro audio builds.

Why Choose the SoundQubed PA8M-8?

• 350W RMS / 700W MAX @ 8Ω — Pro-grade power handling in an 8" midrange — built for high-output competition and demo builds.
• 98 dB Sensitivity (1W/1m) — Exceptionally high efficiency — delivers massive output with relatively modest amplification.
• Ferrite + Neodymium Hybrid Motor (30 + 3 oz) — Best of both worlds — neodymium flux density for sensitivity, ferrite thermal mass for sustained high-power performance.
• 7.6mm One-Way Xmax — Serious linear excursion for an 8" midrange — moves real air at high output without distortion or mechanical failure.
• 1.5" CCAW Voice Coil on Glass Fiber Former — Lightweight, thermally efficient winding on a rigid former — handles sustained high-power use without thermal compression.
• Non-Pressed Paper Cone — Low-mass, natural-sounding cone material for fast transient response and detailed midrange reproduction at high output levels.
• Aluminum Basket — Rigid, resonance-free basket construction — pro audio grade in a car audio package.
• 8Ω Impedance — Ideal for high-power pro audio amplifier configurations — verify your amplifier is stable at 8Ω before purchasing.

Installation & Pairing Recommendations

Crossover Configuration: The PA8M-8 is a dedicated midrange driver — always use a high-pass crossover set at 125 Hz minimum to protect the driver and keep it operating in its optimal range. For competition and high-output builds, use an active crossover or DSP to set precise HPF and LPF crossover points. A band-pass configuration (125 Hz HPF / 5–8 kHz LPF) is recommended for maximum output and driver protection.

Amplifier Pairing: The PA8M-8 handles 350W RMS at 8Ω. Use a dedicated amplifier channel rated for at least 200–350W RMS at 8Ω. Verify your amplifier’s 8Ω power rating before purchasing — many car audio amplifiers are rated at 4Ω or 2Ω and may produce significantly less power at 8Ω.

Pro Audio Lineup Context: The PA8M-8 sits between the PA6B-4 (6.5", 300W RMS, 4Ω, HPF at 160 Hz) and the PA10M-8 (10", 500W RMS, 8Ω, HPF at 80 Hz) in SoundQubed’s pro audio midrange lineup. Choose the PA8M-8 when you need 8" cone area and 8Ω impedance in a high-output midrange application.

Mounting: The PA8M-8 requires a 7.09" / 180mm baffle cutout and 3.44" / 87.5mm mounting depth. Overall diameter is 8.31" / 211mm, overall depth is 3.81" / 96.7mm. Motor diameter is 4.72" / 120mm. Verify your mounting location provides adequate depth clearance before purchasing.

Frequently Asked Questions

Q: Is the PA8M-8 a subwoofer or a midrange driver?
A: It’s a dedicated pro audio midrange driver — not a subwoofer. Its frequency response of 80 Hz–8 kHz and Fs of 128 Hz make it ideal for midbass and midrange duty in a high-output system. Always use a high-pass crossover at 125 Hz minimum and a low-pass crossover at 5–8 kHz to keep it in its optimal operating range.

Q: How does the PA8M-8 compare to the PA6B-4 and PA10M-8?
A: The PA6B-4 is a 6.5" round driver at 4Ω (300W RMS, HPF at 160 Hz) — ideal for standard 6.5" locations. The PA8M-8 is an 8" driver at 8Ω (350W RMS, HPF at 125 Hz) — more cone area and lower crossover point. The PA10M-8 is a 10" driver at 8Ω (500W RMS, HPF at 80 Hz) — maximum cone area and the lowest crossover point in the lineup. Choose based on your available mounting location and desired crossover point.

Q: What amplifier should I pair with the PA8M-8?
A: The PA8M-8 handles 350W RMS at 8Ω. Use a dedicated amplifier channel rated for at least 200–350W RMS at 8Ω. Many car audio amplifiers produce significantly less power at 8Ω than at 4Ω — check your amplifier’s 8Ω spec before purchasing.

Q: Is this sold as a pair or single?
A: The PA8M-8 is sold as a single speaker. Order quantity two for a stereo pair.
