It is designed to add depth, scale, warmth and realism to music and movies while preserving the natural character of the main speakers. Combining REL’s long-standing subwoofer expertise with a striking mid-century-inspired cabinet design, the Classic 99 delivers a richer, deeper and more powerful performance than the Classic 98, making it the ideal choice for larger rooms and more capable sound systems.\u003c\/p\u003e\n\u003cp\u003eCreated for serious two-channel hi-fi systems and home cinema setups, the Classic 99 produces bass that feels effortless, controlled and highly musical. It delivers the kind of low-frequency foundation that transforms the listening experience, revealing texture, atmosphere and dynamic contrast often hidden in recordings.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eLarger Cabinet, Bigger Sound\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe REL Classic 99 takes the design philosophy of the Classic series and expands it significantly. With approximately 50% greater cabinet volume than the Classic 98, it is engineered to move more air, produce greater scale and deliver deeper bass extension.\u003c\/p\u003e\n\u003cp\u003eThis increased enclosure size allows the subwoofer to energise larger spaces with ease, creating a broader, fuller soundstage while maintaining excellent low-frequency control. The larger internal volume helps improve efficiency, bass depth and overall authority.\u003c\/p\u003e\n\u003cp\u003eIts \u003cstrong\u003esealed acoustic suspension cabinet design\u003c\/strong\u003e plays an important role in performance. Unlike ported alternatives, the sealed design offers faster transient response, better timing and tighter bass control, making it particularly effective for music reproduction.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eCustom 12-Inch Long Throw Driver\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAt the centre of the Classic 99 is a specially designed \u003cstrong\u003e12-inch down-firing long-throw bass driver\u003c\/strong\u003e, developed specifically for this model.\u003c\/p\u003e\n\u003cp\u003eThe cone uses \u003cstrong\u003ehot-pressed lightweight paper pulp construction\u003c\/strong\u003e, chosen for its excellent balance of stiffness, speed and natural tonal behaviour. REL’s use of a hand-finished centre cap with randomised paper fibres improves self-damping characteristics, reducing unwanted resonances and allowing the driver to return to silence more quickly.\u003c\/p\u003e\n\u003cp\u003eThis creates cleaner bass notes, stronger attack and greater clarity, especially during demanding dynamic passages.\u003c\/p\u003e\n\u003cp\u003eKey driver benefits include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFaster low-frequency response\u003c\/li\u003e\n\u003cli\u003eBetter tonal texture and realism\u003c\/li\u003e\n\u003cli\u003eReduced overhang and distortion\u003c\/li\u003e\n\u003cli\u003eImproved dynamic impact\u003c\/li\u003e\n\u003cli\u003eGreater low-frequency authority\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe down-firing configuration also helps distribute bass more evenly throughout the room, making placement more forgiving.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e450W Class D Amplifier with High Current Delivery\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003ePowering the Classic 99 is a \u003cstrong\u003e450-watt Class D amplifier\u003c\/strong\u003e, delivering substantial output with speed, efficiency and control.\u003c\/p\u003e\n\u003cp\u003eREL has used proven amplifier technology refined over thousands of subwoofer builds, ensuring stable performance and excellent reliability.
