Key Advantages

1. Open Baffle Special Tuning

   Qts 0.7 optimized for unenclosed baffle design, avoids box boomy bass, outputs clean, natural mid-bass and deep low frequency, ideal to pair with full-range drivers to complete full spectrum audio performance.
2. Precision LMS Professional Calibration

   All parameters measured by LinearX LMS professional speaker testing system, impedance curve smooth with stable low-frequency peak, minimal distortion under medium and large volume playback.
3. High-Efficiency Bass Output (93.6dB Sensitivity)

   High sensitivity matches low-power tube amplifiers and solid-state amps; easy to drive without high power demand, retains dynamic bass texture for vocal, classical and jazz music.
4. Durable High-Quality Construction

   Heavy-duty cast aluminum frame for stable vibration suppression; long-stroke voice coil structure to reduce bottoming; high-loss surround absorbs unwanted resonance, delivering tight, punchy bass with low distortion.
5. Smooth Impedance Curve Performance

   Low-frequency impedance peak neatly positioned at Fs 35.36Hz, gentle impedance rise at mid-high frequency, excellent amplifier load compatibility, no unstable impedance interference with audio signal output.

Application Scenarios

• DIY open baffle HiFi audio systems

• Match 8/10/12-inch full-range speakers for low-frequency compensation

• Vintage tube amplifier home audio setups

• High-fidelity two-channel passive audio systems

• Audiophile personal listening rooms & study music playback

Warm Tips

1. This unit is optimized for open baffle bass compensation, not recommended for traditional sealed/ported closed cabinet use.

2. Pair with matched full-range speakers for balanced 20Hz–20kHz full frequency playback.

3. Suitable for amplifier power between 30W–120W for best dynamic bass performance.
