Ampeg EXTREME SERIES PR-1528HE - Manual (Page 2)

INTRODUCTION:
Inspired by two of the most accomplished bassists of our day, Ampeg’s new PR-1832HE
and PR-1528HE Bass Enclosures are truly a performing musician’s dream come true.
Outstanding sound and legendary Ampeg performance have been embodied in rugged, styl-
ish 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 advan-
tage 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.

removable swivel casters and heavy-duty self-retracting side handles make the cabinet easy
to move.
