The PreSonus 328AI Three-Way 2,000W Powered Dual 8" Loudspeaker with Active Integration is a compact PA enclosure with full-range sound and performance. It features dual 8" ferrite woofers for low frequencies and a custom-designed 8" coaxial speaker with a 1.75" titanium compression driver. These transducers are driven by 2,000W RMS of triamplified, Class D power.
Coaxial systems mount two drivers on the same axis, thus providing a single-point source for a consistent acoustic center. This results in symmetry of response on both the horizontal and vertical axes, at any given angle. The crossover transition is seamless at all angles. The onboard 96kHz/32-bit floating point DSP employs Temporal Equalization to perfect coaxial performance.
The 328AI has flexible connectivity, featuring an XLR/TRS combo input as well as an XLR microphone input. The microphone input provides an XMAX Class A preamplifier and 12V phantom power. An additional XLR mix output can send a parallel signal to another powered speaker. Wireless and wired speaker level-attenuation can be controlled via USB and Ethercon connections.
The plywood enclosure is pole-mountable and has two ergonomic side handles, M10 fly points and allows stable stacking. Four DSP preset Operation Modes optimize performance to the application, including MP3 playback, live performance, or stage monitoring as well as a custom user preset using the SL Room Control software for Mac, Windows and iPad.
