Description
Its BMS 4590 Double diaphram‚The BMS annular midrange diaphragm has a smooth linear response across a frequency range of 400 to 7000 Hz. The substantial diaphragm excursion of max. +/- 0.8 mm leads in high output and enhances power handling up to 1300 W peak. The extremely light annular diaphragm for the high range provides remarkable transient response with very high efficiency between 6 and 22 kHz. In a normal full range compression driver‚ the phase plug must be positioned quite near to the diaphragm‚ limiting diaphragm excursion and compromising middle frequency performance. A common 2" dome compression driver has a restricted high frequency response. Above 8 kHz‚ the dome diaphragm breaks up‚ resulting in resonance and a harsh metallic sound.
