Volt BM2500.4 Bass-Mid Size:261x261mm

10" Paper Cone Mid/Bass

The BM2500.4 uses a massive magnet with a symmetrical field, extended pole piece and long voice coil for maximum linearlty. The cone, linen surround and dome are critically matched and doped to ensure very low midband colouration. The result is an analytical sound quality with a stunning dynamic range.

The BM2500.4 is designed for use in 2-way nearfield monitors where accuracy and realism are essential.
