Product Description

1. Professional Acoustic Testing

During new product development, LONVIN conducts comprehensive testing and adjustment of electro-acoustic parameters—including sensitivity, frequency response, and directivity—in professional acoustic laboratories. With meticulous precision and a commitment to excellence, we focus on crafting acoustic masterpieces.

2. 4-inch Silk Dome Tweeter

The tweeter diaphragm is made of premium silk film coated with special damping material, delivering a soft tonal texture and flat frequency response. Capable of extending high frequencies up to 20kHz and beyond, it enhances treble clarity while ensuring bright, non-fatiguing highs.

3. 6.5-inch Professional Mid-Bass Driver

Featuring a newly designed high-strength diaphragm with long-stroke and high-power architecture, this driver delivers dynamic low-frequency output for impactful bass. Paired with an energy-absorbing rubber surround, it ensures deep bass extension down to 40Hz.

4. 88dB High Sensitivity

With 88dB sensitivity, D2 requires minimal amplifier power to drive—avoiding instability common in high-sensitivity speakers while maintaining low distortion, making it compatible with small amplifiers and tube amps.

5. 200W High Power Handling

D2 boasts a continuous undistorted power (RMS) of 30Wx2 for tweeters and 50Wx2 for mid-bass, enabling seamless reproduction of dynamic musical scenes with immersive impact.

6. Audiophile-Grade 2-Way Crossover

Engineered for professional tuning, the crossover enhances treble detail and high-frequency extension while ensuring smooth, natural transitions between the mellow midrange and delicate highs.

7. Front-Mounted Hyperbolic Dual Ports

Designed to optimize airflow with smooth, turbulence-free passage, these ports eliminate airflow whistling (common in standard ports) for purer sound and deeper, more substantial bass.

8. 12mm High-Strength MDF Enclosure

Constructed from 12mm-thick high-density MDF (each enclosure weighing 3kg), the robust design minimizes resonance and ensures acoustic stability.

9. Pure Copper Gold-Plated Binding Posts

Featuring low contact resistance, these posts reduce signal transmission loss, preserving audio fidelity for pristine sound quality.

10. 20mm Professional Sound-Absorbing Cotton

Both enclosures are lined with 20mm-thick peak-shaped acoustic cotton to suppress resonance and standing waves, minimizing interference and enhancing sound purity.

11. Exquisite Protective Mesh Covers

Included with D2, the mesh covers safeguard drivers from dust, debris, and physical damage while allowing easy disassembly for cleaning.
