This full-range, high powered amp is designed especially for acoustic stringed instruments. With performance that gives new meaning to the phrase 'loud and clear', this diminutive, triamped powerhouse delivers studio-quality sound at stunning volume levels. The 250 Watt, single-channel Loudbox, features an 8 in. woofer, 4 in. polypropylene mid driver and two 1 in. soft-dome neodymium tweeters.
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. The innovative Loudbox enclosure leans back 10 degrees for better dispersion of highs and tighter lows. When you need even more angle, an integrated 't-bar' kick stand allows you to tilt the amp back as much as 70 degrees, converting the Loudbox into an effective near-field floor monitor.
Fishman's decision to go with a tri-amped, three-way speaker system was driven entirely by their quest for amplified clarity and sheer volume. To achieve the sound quality and power they were looking for, a two-way system just couldn't cut it; that would sacrifice the system's response or over-burden the drivers. Once Fishman added the midrange driver to the equation, all these problems evaporated.
Taking a cue from commercial sound reinforcement systems, the three power amplifiers that drive the Loudbox 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 midrange frequencies and two softdome neodymium tweeters top off the treble.
The tweeters in the Loudbox are identical to those used in the best studio mastering monitors; they produce a smooth, sweet treble that is perfect for acoustic instruments. With two of these tweeters, you get great dispersion and high SPLs, without the unpleasant "honk" of a high frequency compression driver found in many so called 'acoustic' amps.
The single-channel Loudbox features an ultra-high impedance input with an EQ section that includes bass, treble, midrange and brilliance controls. Like a high-performance sports car, Fishman decided to keep the layout simple and straightforward. The Loudbox has a greater than 116dB 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's notch filter and phase switch. A sweet-sounding spring reverb, mute switch, effects loop, and an XLR output round out the features.
