12" long-excursion downward-firing driver • 500W RMS Class D amplifier • sealed-box design • DSP Music / Movie / Impact modes • LFE, low-level, and high-level inputs
The Acoustic Energy AE308 Powered Subwoofer in Black is a high-performance sealed subwoofer designed to add serious low-frequency extension, control, and impact to both hi-fi and home theater systems. With a 12-inch high-excursion doped and stiffened paper-cone driver, a 500W RMS Class D amplifier, and DSP-based listening modes, it is engineered to deliver deep, tunable bass while remaining compact enough for more design-conscious living spaces.
System note: the sealed cabinet and DSP tuning options make this a strong fit for listeners who want both musical accuracy and theater-level authority from one subwoofer.
12-inch downward-firing driver — the high-excursion doped and stiffened paper-cone woofer is designed to combine deep bass output with good control and reduced distortion.
Sealed cabinet architecture — the enclosure avoids ports entirely, helping prioritize accuracy, transient response, and better integration with main speakers.
DSP listening modes — Acoustic Energy includes three selectable EQ modes so the subwoofer can behave in a more balanced way for music, hit harder for movies, or prioritize maximum impact when desired.
Simple tuning controls — rotary crossover and phase adjustments allow finer matching to your room, speakers, and listening position.
In a properly integrated system, the Acoustic Energy AE308 Powered Subwoofer in Black delivers low bass that feels substantial and room-filling while still staying disciplined enough for serious music listening.
It is a sealed-box design with a downward-firing driver.
