Mackie HD1501 Aktiivinen subwooferi

15" Powered Subwoofer 600W RMS/1,200W Peak. The 15" HD1501 balances chest pounding thump with a truly musical Symmetrical Linkwitz-Riley crossover circuit, which lets you dial in the low-end impact right where your system needs it. Its own internal EAW amplifier supplies the HD1501 with 600 watts of power (1,200 watts peak), allowing it to generate a massive 131dB output. That's easily enough output to keep up with most midsize PA rigs.
