Its trilaminated sandwich diaphragm places a Nomex honeycomb core between two fiberglass skins, creating a rigid, lightweight cone engineered to remain controlled through demanding low-frequency passages. A wide rubber surround supports the driver’s extended excursion.\u003c\/p\u003e\n\u003cp\u003eLow-frequency response reaches 25 Hz at -6 dB, giving music greater foundation and cinematic effects convincing impact without relying on a conventional port.\u003c\/p\u003e\n\u003ch2\u003e600-Watt Class AB Amplification\u003c\/h2\u003e\n\u003cp\u003eA high-performance Class AB amplifier supplies 600 watts RMS and up to 900 watts peak.
