SoundQubed QP-MR 8" Pro Audio Midrange Speakers (pair)

The SoundQubed QP-MR8 is an 8-inch midrange driver engineered for high‑fidelity car audio builds, delivering articulate vocal and instrument detail to balance a subwoofer‑heavy system. As a midrange‑only speaker in the QP series, it’s suited for enthusiasts pursuing precise midrange control within component sets.

• Impedance: Single 4 Ω load — compatible with a wide range of car amplifiers and easy to integrate into a multi‑speaker system.
• Sensitivity: 93 dB (1W/1m) — defines how loud the driver will play with a standard wattage at one meter, helping plan effective amplification.
• Continuous Power: 100 W RMS — supports steady listening levels without distortion in typical installations.
• Music Peak Power: 200 W peak — handles transient dynamics without damage when driven within the rated limits.
• Frequency Response: 80 Hz–8 kHz — specifies the usable midrange window focused on voices and instruments for clear articulation.
• Coil Diameter: 1.5" — coil size contributes to the speaker’s excursion and power handling capabilities.
• Magnet Weight: 18 oz — provides stable magnetic control for consistent midrange performance under dynamic music content.
• Useable Throw: 16 mm — cone excursion that supports the midrange’s dynamic response within its frame.
• Overall Diameter: 8.25 inches — outer size to consider for fitment in larger mounting openings.
• Mounting Diameter: 7.18 inches — cutout diameter required for installation.
• Mounting Depth: 3.18 inches — recommended depth to ensure proper enclosure and panel clearance.
• Freq. Range Spec: 80 Hz–8 kHz — aligns with midrange duties and helps balance a subwoofer with a suitable tweeter.
• Speaker Type: Midrange‑only driver (not a coaxial speaker) — if replacing coaxial speakers, you’ll need to add tweeters to cover highs.
• Enclosure Guidance: Requires less than 0.25 cu ft of airspace per pair in a sealed enclosure — supports compact installations and predictable sonic performance.

In a typical car build, the QP‑MR8 fills the midrange gap left by a sub, enabling clear voices and instrument textures without demanding excessive amp power. When used with a subwoofer and a QP series tweeter, it contributes to a balanced full‑range presentation; if you’re replacing a coaxial with this midrange, plan for additional high‑frequency drivers. The sealed enclosure requirement helps keep performance consistent in tight spaces.
