Its down-firing 10-inch paper-cone driver and 300-watt Class D amplifier are voiced for natural, slightly warm bass rather than an overly aggressive presentation.

Its warm tonal balance and High-Level connection are especially well suited to two-channel listening, while the dedicated .1\/LFE input allows it to provide additional low-frequency impact in a home theater system. High-Level and .1\/LFE inputs can also be operated simultaneously.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan the Classic 98 be used with other REL subwoofer models?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes.

(14-37 sq. m.). Its 10-inch down-firing driver, 300-watt amplifier, and closed-box cabinet can generate broad, room-filling bass while maintaining a natural musical character. Final performance will also depend on room acoustics, speaker choice, placement, and listening level.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan REL Classic 98 subwoofers be vertically stacked into a line array?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eNo. Classic 98 is intended for conventional floor placement rather than vertical line-array stacking. For higher-performance two-channel systems, a stereo pair of Classic 98 subwoofers can improve clarity, soundstage definition, transparency, and bass balance; REL's Serie S and Reference models are better suited to dedicated line-array applications.\\\u003c\/dd\u003e \u003c\/dl\u003e \u003ch4\u003eREL Classic 98 Downloads:\u003c\/h4\u003e \u003cp\u003e\u003ca href=\"https:\/\/storage.googleapis.com\/lupublic\/REL_Classic_98_Manual.pdf\" title=\"REL Classic 98 Manual\"\u003eREL Classic 98 Manual\u003c\/a\u003e\u003c\/p\u003e","brand":"REL","offers":[{"title":"Default Title","offer_id":44494146273439,"sku":"REL-CLASSIC98-WAL","price":1499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0495\/6910\/4031\/files\/da06f6af-a4e4-4f0f-bbd3-9cff7babf1a4.jpg?v=1788544749"},{"product_id":"rel-classic-99-downward-firing-subwoofer-in-walnut","title":"REL Classic 99 Downward Firing Subwoofer in Walnut","description":"\u003ch3\u003eREL Classic 99 Subwoofer\u003c\/h3\u003e \u003cp\u003eThe REL Classic 99 is a premium powered subwoofer designed for listeners who want the warmth and visual character of classic hi-fi combined with the output, control, and reliability of modern REL engineering.

Its 24Hz in-room extension, strong dynamic capability, and refined low-level detail make it especially well suited to music-focused systems and larger listening spaces.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan the REL Classic 99 be used for both music and home theater?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes. The Classic 99 is particularly focused on musical performance, but its dedicated .1\/LFE RCA input also provides powerful low-frequency effects for movies. High Level and .1\/LFE connections may be used simultaneously, allowing one subwoofer to support the main speakers during stereo playback and reproduce the dedicated LFE channel during home theater use.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eCan the Classic 99 be used with other REL subwoofers?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes. It can be integrated with other REL models when the system is carefully positioned and calibrated, although similarly voiced models generally make integration easier. For the most consistent imaging and bass distribution, a matching pair of Classic 99 subwoofers is an especially effective option.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eDoes the REL Classic 99 support wireless operation?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eYes, with an optional REL wireless accessory. The Classic 99 is compatible with AirShip II and HT-Air MKII, both sold separately; AirShip II supports REL High Level and .1\/LFE operation, while HT-Air MKII supports Low Level or .1\/LFE connectivity.\u003c\/dd\u003e \u003cdt\u003e\u003cstrong\u003eWhat room sizes are best suited to the Classic 99?\u003c\/strong\u003e\u003c\/dt\u003e \u003cdd\u003eThe Classic 99 is intended for capable systems and medium-to-large rooms, with approximately 150 to 400 square feet being a suitable range.
