The transducers are implemented in a K- shape conguration. The K1 enclosure is based on a 3-way active design with 2 LF sections, 1 MF section and 1 HF section, each one at the nominal impedance of 8 ohms. The K1 enclosure is made of rst grade Baltic birch plywood to ensure maximum acoustical and mechanical integrity.
Refer to the LA8 / LA12X owner's manual for detailed instructions about the whole cabling scheme, including modulation cables and network. Rigging elements Rigging elements or procedures are not presented in this document. Refer to the K1 rigging manual. K1 user manual (EN) version 6.0...
There are two distinct applications for K1-SB in a K1 system: • As an LF extension in a line source for enhanced throw, using the [K1SB_X] preset with K1. • As a subwoofer for increased impact, using the [K1SB_60] preset.
• K1/K1-SB line source: enhanced LF throw By providing the K1-SB with the same frequency response as the K1 low section, the [K1SB_X] preset allows the K1-SB enclosure to be used as an LF line source element, increasing the length of the sub-low line source.
