Footnotes:
1: Based on speaker preset selection and cabinet orientation/configuration.
2: Peak, unweighted SPL, measured under
half-space
conditions at 1 meter using broadband pink noise with a 12 dB crest factor and specified preset.
3: IEC Standard: IEC shaped noise with 6 dB crest factor based on nominal impedance and a duration of 100 hours. Continuous is defined as 2x RMS.
4: For more information on how to power B15 subwoofers, refer to the
VTX B15 User Manual
.
5: Nominal impedance within the stated frequency range of the product. Minimum impedance is 6.1 Ω at 38 Hz and 180 Hz.
6: Front face at 0 degrees or greater down angle to allow the cabinet to drain water. Suspension components fully weather rated for indoor or covered outdoor conditions where humidity is nominally under 50% and not local
to bodies of corrosive materials. Unused speakON connectors must be sealed using silicone to protect against water and moisture.
