BMS 4510ND The BMS 4510 features a 1" x 4" planar exit for use in line arrays. The 4510 radiates a coherent planar wave front from the rectangular piston without internal diffraction for superior dispersion control, high fidelity sound, and virtual lack of destructive interference from driver to driver when used with 10 degrees of vertical splay or less. The 4510 is very versitile as it can be used with two units and 8" cones, three units and 12"/6" cones, or four units and 15"/8" cones. The 4510 is the HF unit used in the Coda LA5A. The exit structure is made of aluminium with additional fins for cooling. The 4510ND sells for $199.00.
