Outstanding sound and legendary Ampeg performance have been embodied in rugged, stylish cabinets which are incredibly road-worthy and surprisingly manageable. The PR-1832HE is a four-way full range bass speaker system inspired by Victor Wooten. This enclosure packs the punch of traditional 2-10 / 4-10 cabinets, but with the added advantage of the built-in 18" subwoofer. This enclosure is designed for high SPL and low distortion. The frequency response is smooth and accurate all the way down to 35Hz. The PR-1832HE features a a single 18", 400 watt, 4" diameter flat wound voice coil sub low frequency transducer, two 10", 150 watt low frequency transducers, two 6 -1/2", 75 watt closed-back mid-frequency transducers, and a bullet horn tweeter. This cabinet is biampable between the 18" sub and the 2-10" low frequency components. Tilt-back cabinet design, 3” dolly-style casters and a heavy-duty rear bar handle make the cabinet easy to move around. Heavy-duty self-retracting side handles facilitate loading and unloading. The PR-1528HE is a three-way full range bass speaker system inspired by Steve Bailey. This enclosure is a small full range powerhouse with an incredibly smooth frequency response, designed specifically for true, accurate sound reproduction to please the most demanding bassist either on stage or in the studio. The PR-1528HE features a a single 15", 300 watt, 4" diameter flat wound voice coil low frequency transducer, two 8", 100 watt mid frequency transducers and a bullet horn tweeter. The cabinet is biampable between the 15" low frequency driver and the 2-8" drivers. Four removable swivel casters and heavy-duty self-retracting side handles make the cabinet easy to move. FEATURES: • Switchable "Full Range" and "Biamp" operation. • High power handling: 400 watts RMS / 800 watts program (PR-1528HE), 600 watts RMS / 1200 watts program (PR-1832HE) • Rugged carpet covered cabinet with extensive internal bracing, tuned low frequency section, and internally enclosed mid and high frequency sections. • Slanted front to accommodate both near and far field use. • Road-tough 16GA perforated steel grill. • Full-range frequency response. • Neutrik® Speakon connectors.

PR-1832HE / PR-1528HE Bass Enclosure OPERATION: The PR-1832HE and PR-1528HE are full range speaker cabinets and can be powered by a single full range amplifier, or bi-amped with one amp for the lows and another for the mids and highs. Either the 1/4” speaker jacks or the Speakon® jacks may be used for connecting to the cabinet. The two 1/4” jacks are internally wired in parallel to each other, as are the two Speakon® jacks. This enables daisy-chaining two or more cabinets together, providing you match your amplifier to the overall impedance load. FULL RANGE OPERATION: • Set the Mode switch to the “Full Range" position. • 1/4” JACKS: Connect the output of your amplifier to either of the two 1/4” jacks labeled “Full Range Inputs (Bi-amp Low Inputs).” Use the remaining 1/4” jack to daisy chain to another cabinet, if desired. • SPEAKON® JACKS: Connect the output of your amplifier to either of the two Speakon® jacks. Use the remaining Speakon® jack to daisy chain to another cabinet, if desired. For full range, wire the Speakon® connectors as follows: Pin 1+ : Full Range positive (+) Pin 1– : Full Range negative (–) BI-AMP OPERATION: • Set the Mode switch to the “Biamp" position. • Set the crossover point for the amplifiers somewhere in the 100Hz to 300Hz range. Once up and running, adjustments within this range may be made to suit y...
