The result is bass that feels tighter, cleaner and better integrated with your main speakers, whether you're listening to detailed acoustic tracks or watching action-packed films.\u003c\/p\u003e\n\u003cp\u003eThe amplifier also offers high-current capability, ensuring consistent performance even during demanding low-frequency passages.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAdvanced 10-Inch FibreAlloy Active Driver\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe T\/9x uses a custom-built 10-inch FibreAlloy active driver designed for speed, rigidity and precision.
