BMS 4555 - 1,5" Hochtontreiber 80 W 8 Ohm

 

• 1,5-inch driver for budget projects
• Unique patented design
• 113 dB sensitivity 1W / 1m
• 1 kHz crossover
• Extended high frequency response up to 20 kHz
• Very small size and low weight
• 44,4 mm voice coil

BMS 4555 is a powerful 1,5´ professional compression driver that delivers excellent sonic quality in a small package. It has an exceptional dynamic range and produces even the most complex music signals with depth and definition.
The BMS exclusive voice coil technology employs a light weigh Cooper Clad Aluminium wire wound inside and outside of the KaptonTM former to improve the heat dissipation, dramatically increasing the acoustic output and reliability of the driver while minimizes the power compression.

The BMS 4555 – 1,5´ compression driver is designed for a wide variety of applications including budget projects requiring 1,5´ driver of high sonic quality.

The 4555 offers all the benefits of the patented BMS compression driver in a 1,5´ format, but at much reduced cost.
