Inspired by REL’s heritage designs and created specifically for vintage and retro-inspired systems, the Classic 98 combines traditional craftsmanship with modern amplifier technology to deliver bass that feels deep, natural, and beautifully integrated.\u003c\/p\u003e\n\u003cp\u003eDesigned with a more relaxed and expressive sonic character than many modern high-speed subwoofers, the Classic 98 brings body and scale to music, adding weight to basslines, realism to drums, and greater atmosphere to soundtracks without overwhelming the rest of your system.\u003c\/p\u003e\n\u003cp\u003eWhether paired with classic floorstanding speakers, compact bookshelf models, or a dedicated home cinema setup, the Classic 98 is engineered to blend seamlessly and elevate every listening experience.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDesigned for Musicality, Built for Emotion\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eUnlike many subwoofers designed for sheer output, the Classic 98 focuses on musical engagement. REL has tuned it to deliver a softer, fuller bass character that fills the room naturally, making long listening sessions more immersive and less fatiguing.\u003c\/p\u003e\n\u003cp\u003eThis makes it especially suited to vinyl playback, jazz, acoustic recordings, classic rock, orchestral music, and atmospheric film soundtracks where texture and warmth matter just as much as depth.\u003c\/p\u003e\n\u003cp\u003eIts sound signature is balanced and inviting, adding scale to your music while preserving the tonal integrity of the main speakers.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e10-Inch Down-Firing Paper Cone Driver\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAt the core of the Classic 98 is a custom-built \u003cstrong\u003e10-inch down-firing bass driver\u003c\/strong\u003e, constructed using REL’s traditional pulp-on-paper cone technique.\u003c\/p\u003e\n\u003cp\u003ePaper remains one of the most respected cone materials in audio because of its natural damping characteristics and lightweight structure. This allows the driver to move quickly and accurately while maintaining a rich, organic tonal quality.\u003c\/p\u003e\n\u003cp\u003eThe down-firing design helps distribute bass energy evenly into the room, creating broader, more natural low-frequency coverage and helping the subwoofer disappear into the soundstage rather than drawing attention to itself.\u003c\/p\u003e\n\u003cp\u003eBenefits include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural bass texture and realism\u003c\/li\u003e\n\u003cli\u003eBetter room-filling bass dispersion\u003c\/li\u003e\n\u003cli\u003eImproved tonal warmth\u003c\/li\u003e\n\u003cli\u003eSmooth integration with stereo speakers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cstrong\u003eAcoustic Suspension Cabinet for Tighter Control\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe sealed cabinet design plays a huge role in the Classic 98’s character. Unlike ported subwoofers, which can prioritise maximum output, the acoustic-suspension design focuses on accuracy, speed, and control.\u003c\/p\u003e\n\u003cp\u003eThis enclosure allows bass notes to start and stop more cleanly, reducing overhang and improving timing.\u003c\/p\u003e\n\u003cp\u003eThe result is bass that feels more connected to the music rather than detached from it.\u003c\/p\u003e\n\u003cp\u003eThis is particularly important for hi-fi listeners who want bass extension without losing detail or rhythm.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003ePowerful 300-Watt Class D Amplifier\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003ePowering the Classic 98 is a modern \u003cstrong\u003e300W Class D amplifier\u003c\/strong\u003e, combining efficiency with excellent low-frequency control.\u003c\/p\u003e\n\u003cp\u003eREL uses Class D technology here not for aggressive output, but for its ability to deliver consistent power, lower heat, and tighter driver control.\u003c\/p\u003e\n\u003cp\u003eThis amplifier gives the Classic 98 the authority to reproduce deep bass with confidence while maintaining composure at higher volumes.\u003c\/p\u003e\n\u003cp\u003eKey amplifier advantages include:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh efficiency operation\u003c\/li\u003e\n\u003cli\u003eLow heat

standout features is its \u003cstrong\u003eHigh-Level connection\u003c\/strong\u003e, allowing the subwoofer to receive the same signal as your main speakers directly from the amplifier.\u003c\/p\u003e\n\u003cp\u003eThis preserves the tonal character, timing, and dynamics of your system, creating more seamless bass integration than many traditional line-level connections.\u003c\/p\u003e\n\u003cp\u003eFor stereo listeners, this is one of the biggest advantages of owning a REL subwoofer.\u003c\/p\u003e\n\u003cp\u003eIt ensures the subwoofer behaves like an extension of your speakers rather than a separate bass source.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDedicated LFE Input for Home Cinema\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eAlongside its High-Level input, the Classic 98 also includes a dedicated \u003cstrong\u003eLFE (.1) input\u003c\/strong\u003e for AV receivers.\u003c\/p\u003e\n\u003cp\u003eThis means it can work in both music and cinema systems simultaneously.\u003c\/p\u003e\n\u003cp\u003eREL’s unique setup allows separate gain settings for High-Level music playback and LFE movie playback, so you can enjoy subtle musical bass and powerful cinematic impact without changing settings every time.\u003c\/p\u003e\n\u003cp\u003eThis makes it ideal for hybrid entertainment systems.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eFully Adjustable Crossover Control\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eWith a variable crossover range from \u003cstrong\u003e30Hz to 120Hz\u003c\/strong\u003e, the Classic 98 can be matched precisely to almost any speaker setup.\u003c\/p\u003e\n\u003cp\u003eThis flexibility means you can optimise the handover between speakers and subwoofer for smoother bass integration.\u003c\/p\u003e\n\u003cp\u003eWhether your speakers already produce strong low frequencies or need more support in the bass region, the Classic 98 can be tailored accordingly.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eREL Filter Technology\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eREL’s advanced

naturally into the system, maintaining a cohesive and balanced soundstage.\u003c\/p\u003e\n\u003cp\u003eRather than simply adding more bass, it enhances the overall scale and realism of your system.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eOptional Wireless Connectivity\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eFor easier placement and cleaner installations, the Classic 98
