The EAW SB730 is engineered to be flown as a companion to KF730 Line Arrays, but this EAW SB730 is perfectly suitable for other applications requiring high output at low frequencies in a highly compact format. Used in arrays of two or more, the EAW SB730's couple to extend the low frequency response. Also, the EAW SB730 has a unique enclosure shape both enhances the acoustical performance and serves to give a solid base for a ground-stacked KF730 array. The EAW 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” arrangement 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. Also, the EAW SB730 has a several different wiring configurations that 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. EAW SB730 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.
