Description
The tri-amped, 600-watt, two-channel Loudbox Pro features a 12" woofer driven by a 380-watt power amp. The 6" polypropylene
mid driver is pushed by 160 watts and the three 1" soft-dome neodymium tweeters also have their own 60-watt amplifier. These
speaker components have been painstakingly designed for high power handling and a smooth, flat acoustic response. Each
component is housed in its own sealed enclosure and tuned precisely for acoustic stringed instruments. For close onstage
monitoring, an integrated kickstand allows you to tilt the amp back as much as 70 degrees.
Our decision to use a tri-amped, three-way speaker system was driven entirely by our quest for amplified clarity and sheer volume.
Most acoustic amplifiers on the market are severely underpowered and just don't have the quality components and/or the
horsepower to honestly reproduce acoustic instruments at concert levels. To achieve the sound quality and power levels we were
looking for, a traditional power amplifier and two-way speaker system just couldn't cut it; we'd sacrifice the system's response or
we would over-burden the drivers. Once we added a midrange driver and three power amps to the equation, all these problems
evaporated.
Taking a cue from commercial sound reinforcement systems, the three power amplifiers that drive the Loudbox Pro deliver cleaner,
less distorted sound through the speakers than any acoustic amplifier in its class. The high-efficiency paper-cone woofer pumps
out the bass, the polypropylene midrange driver handles the crucial mid frequencies and three soft-dome neodymium tweeters top
off the treble.
The tweeters in the Loudbox Pro are identical to those used in the best studio mastering monitors; they produce a silky smooth
treble that is perfect for acoustic instruments. With three of these tweeters, you get great dispersion and high SPLs, without the
unpleasant "honk" of high-frequency compression drivers found in many other acoustic amplifiers.
The two-channel Loudbox Pro features ultra-high impedance instrument inputs with EQ sections that include bass, midrange, treble
and brilliance controls. Loudbox Pro has a greater than 122 dB SPL rating, so the big thrills with this amp come when you step on
the gas and feel the surge of power. Fighting acoustic feedback is straightforward with the Loudbox Pro's notch filters and phase
switches. A sophisticated digital reverb with five useful settings can be assigned to either (or both) channel(s). A mute switch, dual
effects loops, and an XLR output with selectable pre/post EQ round out the features.
