The low price is because it will need to be checked since it plays with less volume than a second one I have. I love that model, fast and easy to integrate.

The REL Acoustics Gibraltar G2 (also known as the G-2) is a reference-grade active sub-bass system designed for high-end two-channel audio and home theater integration. Built to deliver the same sound signature and filter circuitry as the flagship G1, the G2 utilizes a slightly smaller footprint to achieve faster transient speed and precise bass control.

Key Technical Specifications

• 10-Inch Long-Throw Driver: Features a continuous-cast carbon-fiber cone that is exceptionally light and rigid, allowing high power handling and linear movement with minimal distortion.
• 450W Class A/B Amplifier: Powered by a high-current analog MOSFET amplifier section, selected over Class D designs for its speed, musicality, and control.
• Ultra-Fast Analog Filter: Utilizes an analog Bessel filter network with a group delay of approximately 4 milliseconds, ensuring seamless phase coherence and time alignment with main loudspeakers.
• In-Room Low Frequency Extension: Frequency response drops down to 18 Hz at -6 dB.
