BMS BMS4595NDH 4595 ND – 1.5″ Coaxial Neodymium Driver 150 W + 80 W 16 Ohm

• Extended Bandwidth (300 - 22000 Hz)
• Neodymium Magnet Assembly
• With two Subsystems in one, each Driver covers a smaller Frequency range for increased Power Handling, high Dynamic and extremely low Distortion
• Excellent Phase Coherence
• Perfect Time Alignment without Problems of Multi-Source Interference
• Ultra light Weight and small Size

The 4595ND is a 1,5" coaxial compression driver delivering a real coherent single point wave front without hot spots with excellent phase coherence and perfect time alignment. The driver is in fact a 2-way system employing two concentric annular ring diaphragms. Each driver covers a smaller frequency range for increased power handling, high dynamic and extremely low distortion.

The larger of the two reproduces middle frequency from 300 Hz upward, crossing over 6,3 kHz to the HF transducer which is capable of reaching 22 kHz. The large diaphragm excursion of max. + / - 0,8 mm results in high output and increased power handling up to 1300 W peak. The voice coils may be driven in conjunction with a passive crossover or driven individually from an active crossover. The outer casting features extensive heatsinking ensuring high power handling and low compression.

150W AES compression driver, 4 διάφραγμα τιτανίου, coherent wave phasing plug, 8Ω

Driver 140WRMS, 108dB, 500-18.000 Hz

2" high frequency compression driver. The particular mylar/titanium
diaphragm using a 3" edgewound flat aluminium wire voice coil and a
optimized high energy ceramic magnet assembly using a copper shorting
ring assembly produce smooth response and excellent sonic properties .
