Jamo SUB 250 Technical Overview - Page 4

Since SUB 550 reaches very low, it features a Boundary Gain Compensation switch, which further helps to keep a flat frequency response, as BGC compensates for the room influence at low frequencies. The level control is placed on the front of the subwoofer, elegantly integrated in the design, with a soft blue light indicating the volume setting. SUB 650 The SUB 650 incorporates a 12" subwoofer driver and an amplifier capable of producing 650 Watts of peak power. This subwoofer works in a closed cabinet, and even if there is no bass reflex port to contribute to a high SPL, it delivers 110 dB sound pressure level. The advantages of a closed cabinet is absolutely absence of port noise and an even better timing resulting in a musical fidelity that is even more accurate and exact than conventional ported systems. The SUB 650 is intended for high performance bookshelf and floorstanding speaker systems. The SUB 650 is capable of reaching down to 24 Hz which is why we have here incorporated the continuously variable Boundary Gain Compensation for optimum integration into the home environment.
