ADAM Audio GTC Subwoofer - Home Theater Loudspeaker


“The system’s low-frequency performance was also among the best I’ve heard, if not the best. If you consider the subwoofer’s modest size and price, that was surprising. The subwoofer produced massive, palpable, dynamically unrestricted, pulsating waves of tuneful, low-frequency, musical energy, along with depth charge–type, room- pressurizing, chest-pressing deep bass on sound effects. The unsubstantiated bursts of unidentifiable bass you get from lesser systems – bass you can hear but not feel, or bass that lacks transient attack – never entered into this system’s low-frequency performance on either music or sound effects.”
