The REL Acoustics HT/1205 MKII establishes a new standard for affordable home theater subwoofers, featuring a lightweight 12-inch CarbonGlas™ driver paired with a powerful 500W NextGen5 Class D amplifier for extraordinary dynamics and precision. Its sealed, front-firing cabinet is solidly braced with 'Magic Brace' internal bracing, finished in line-grained black composite with a high-gloss lacquer top plate. Engineered for pure home theater use, it delivers 50% louder output than its predecessor, with flat bass response down to the low 20Hz range thanks to specially adapted input filters. Optional HT-Air wireless capability enables uncompressed .1/LFE signal transmission. Suitable for both cinema and music, it offers high output levels typically found in pricier models.
