Stunning dynamic range
superb accuracy and realism
The BM2500.4 is designed for use in two way nearfield studio monitors where accuracy and realism are essential. The BM2500.4 uses a massive magnet with a symmetrical field, extended pole and exceptionally long voice coil for maximum linearity. The cone, linen surround and dome are critically matched and doped to ensure very low midband colouration. The result is analytical sound quality with a stunning dynamic range.
