DESCRIPTION
The R2-66MAX is a three-way, full-range loudspeaker system
designed to provide "No Compromises" premium music
reproduction at very high output levels, and also improves the
legendary R2 voice projection and intelligibility capabilities.
It is designed with the same materials and construction
as the standard R2 for extreme weather resistance, and
can withstand long-term exposure to tough environmental
conditions.
The R2-66MAX is constructed with premium components
in a biamp format to maximally optimize its performance. It
uses a 1.4" exit HF compression driver that features a copper
shorting ring and hybrid diaphragm to reduce resonances
while maintaining excellent HF extension. Operated with a
high crossover frequency, the large HF driver maintains very
high headroom, delivering effortless performance. The dual,
high power 12" LF drivers feature an aluminum demodulation
ring for very clean, low distortion performance. The midrange
features a higher performance version of the legendary low
compression ratio M200 2" exit compression driver, achieving
3 dB greater output with extremely low distortion. The passive
MF/HF horn signal aligns the drivers for the best possible
music and speech performance. The result is an excellent
loudspeaker system that is capable of exceeding expectations
in any application.
Community strives to improve its products on a continual basis. Specifications are therefore subject to change without notice.

ARCHITECTURAL SPECIFICATIONS
The loudspeaker system shall be a horn-loaded, three-way, full-range triaxial design with two 12" inherently weather-resistant neodymium
low frequency drivers on a bass horn, one 2" exit Ferrofluid-cooled midrange compression driver with a nonmetallic diaphragm and one
1.4" exit HF driver with a titanium/mylar hybrid diaphragm mounted on respective fiberglass horns built within the bass horn. MF/HF
drivers shall be connected to an integral passive crossover with a crossover frequency of 3300 Hz, the electronic biamp LF/MF crossover
frequency shall be at 450 Hz. The biamp input connection shall be two 16-2 12' (3.6 m) SJOW cables with stripped ends, one for LF and
