SB730

SUBWOOFER

The SB730 is designed to be flown as a companion to KF730 Line Arrays, but is suitable for other applications requiring high output at low frequencies in a highly compact format. Used in arrays of two or more, the SB730s couple to extend the low frequency response.

Product Description

The unique enclosure shape both enhances the acoustical performance and serves to provide a solid base for a ground-stacked KF730 array. The SB730 enclosure is 1.5 times the height of a KF730, which allows attractive KF730/SB730 arrays to be assembled in a 3:2 ratio.

The “clam shell” arrangment of its two, advanced design, 12 inch woofers provides tighter driver coupling to increase output and maximize LF “punch”. A massive port radiates the considerable energy needed at the enclosure’s tuning frequency to complement the KF730s output at other frequencies.

Several different wiring configurations are permitted. In addition to Neutrik® NL4 input and loop-through connectors, an NL8 connector accepts amplifier outputs for both SB730s and KF730s using a single amplifier rack cable. Additional SB730s and KF730s are then daisy chained from one SB730. This allows powering up to eight KF730s and four SB730s with just four amplifier channels.

The enclosure features integral skids and companion recesses so that enclosures interlock to stabilize stacked SB730s. Heavy duty handles and an optional caster pallet facilitate transporting.

Six year warranty.
