The GTO5355 has been engineered to ensure optimum power delivery into numerous impedances with low distortion. It comes outfitted with a variable 12dB per octave electronic crossover allowing you to optimize system tuning based on speaker location and accompanying loudspeaker components. The GTO5355 is designed to drive a complete system using its four full range channels and powerful single subwoofer channel. To further improve your system's performance, we would suggest that that you also add a pair of JBL's GTO loudspeakers and subwoofers.
