Key Features:

• Extended Bandwidth (300 – 22.000 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
• 8Ω

Product Details:

• In a conventional full range compression driver the phase plug must be located extremely close to the diaphragm, excursion of the diaphragm is limited and middle frequency performance is compromised.
• A typical large diaphragm dome compression driver has a limited high frequency response.
• Over 8 kHz the dome diaphragm breaks up causing resonance and harsh, metallic sound.
• The patented design of the BMS 4594 is a result of extensive dedicated research and development providing dramatic improvement in dynamic response, clarity and transparency.
• The BMS annular midrange diaphragm covers the frequency range between 300 and 7.000 Hz with a smooth, linear response.
• The large diaphragm excursion of max. +/-0.8 mm results in high output and increased power handling up to 1.300 W peak.
