arrayable bass cabinet

 

RA18 is a new element of the PalcoPlus™ line-array system, designed to further increase the system's flexibility of use and tonal quality.
It is a vented ‘arrayable bass cabinet’ having the same frontal size of two RA16 loudspeakers and with integrated steel suspension fittings that are compatible with model B1 and B2 bumpers and with the RA16' fittings. The combination of RA18 and RA16 allows to project and install compact and efficient audio systems able to reproduce the complete audio spectrum even when you can’t or don’t want to use floor-standing subwoofers. Indeed RA18 allows to significantly increase the lower octave's sound pressure level generated by the suspended system, thus increasing the already it's large dynamic range, transforming the array in a great array.
RA18 is fitted with an 18" LF driver, purpose-built for this project, with neodymium magnet and a 4” voice coil, and it can boast an excursion of ±15,5 mm. Moreover RA18 allows to further increase the remarkable low frequency ‘punch’ of the RAB1815 cardioid woofer. RA18 (1700W@4ohm) is designed to be driven by one channel of the PLM6800 powered controller, and it is rated for over 130 dB continuous SPL in the 50÷100 Hz frequency range.
It may be supplied in a special version, RA18X, with a custom LF driver (rated at 3400W@8ohm) featuring a carbon fiber cone and a 5.3" voice coil, that may be driven by two bridged channels of one PLM6800. Two Neutrik 8-pole Speakon® connectors (a single one on RA18X model) provide simple and intuitive connection to the PLM6800 powered controller or to any other power amplifier
A single PLM6800 can drive four RA18 units  or two RA18X units.
In order to simulate on Ease Focus an array made of RA18 and RA16 use the file PalcoPlus_Montarbo_1_10.efo (available in the download section).
