{"product_id":"rel-s850-subwoofer","title":"REL S\/850 Subwoofer","description":"\u003cp\u003eA serious subwoofer should make the entire system feel larger, clearer, and more convincing without making the room feel like it was built around bass.\u003c\/p\u003e \u003ch3\u003eWhen Output Alone Is Not the Whole Answer\u003c\/h3\u003e \u003cp\u003eIt is easy to compare subwoofers by driver size, wattage, and low-frequency extension. Those numbers matter, but they do not explain why one subwoofer can add weight while another makes the main speakers feel more natural, more expressive, and more complete.\u003c\/p\u003e \u003cp\u003eThe better question is not only how deep it plays. The better question is whether it can support music and movies without pulling attention away from the system or flattening the emotional pull of the performance.\u003c\/p\u003e \u003ch3\u003eSerie S Scale With Proper REL Integration\u003c\/h3\u003e \u003cp\u003eWe chose the REL S\/850 because it brings flagship Serie S performance into a form that can work in serious music and theatre systems without dominating the room visually. It uses a 12-inch CarbonAlloy active driver, a 12-inch down-firing passive radiator, and an 850-watt Linear Class D amplifier for scale, speed, and control.\u003c\/p\u003e \u003cp\u003eJust as important, the S\/850 includes REL’s High Level Neutrik Speakon input, low-level inputs, LFE RCA, and LFE XLR. That gives it the connection flexibility needed for a refined two-channel system, a theatre system, or a higher-performance room where both matter.\u003c\/p\u003e \u003ch3\u003eWhat the Specs Won't Tell You\u003c\/h3\u003e \u003cp\u003e\u003cstrong\u003eIt Builds Scale Without Turning Bass Into a Trick\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe S\/850 has the output and extension to add real weight, but the point is not simply more bass. Properly matched and tuned, it helps the main speakers sound larger and more relaxed while preserving the tone, timing, and space that make music feel more human and believable.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eIt Gives Movies Weight Without Sacrificing Music\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe separate LFE inputs allow the S\/850 to handle cinema effects with authority while the high-level connection keeps music tied to the main amplifier and speakers. That matters in a room where the same system has to carry an intimate acoustic track one night and a full soundtrack the next.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eIt Belongs in Better Systems\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe S\/850 makes the most sense when the speakers and electronics are already capable enough to show what a better subwoofer can do. In that kind of system, the change is not only deeper bass. Vocals gain body, acoustic instruments feel more authentic, and the space around the performance becomes easier to hear.\u003c\/p\u003e \u003ch3\u003eThe Audio Two Verdict\u003c\/h3\u003e \u003cp\u003eThe REL S\/850 is the Serie S model we would look at when the system deserves more than theatre impact alone. It is built for rooms where music quality still matters, where the main speakers are already good, and where the subwoofer should improve the whole presentation rather than simply announce itself.\u003c\/p\u003e \u003cp\u003eThis is the kind of REL that can make a strong speaker system feel like it moved up a class. When it is placed and tuned correctly, you should notice more scale, more ease, and more emotional connection, then notice immediately when it is turned off.\u003c\/p\u003e \u003ch3\u003eTech You Can Hear\u003c\/h3\u003e \u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eWhat You Hear\u003c\/th\u003e\n\u003cth\u003eWhy It Happens\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e \u003ctr\u003e\n\u003ctd\u003eMusic gains body without losing texture\u003c\/td\u003e\n\u003ctd\u003e12-inch CarbonAlloy active driver with controlled cone structure\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eThe system feels larger and less strained\u003c\/td\u003e\n\u003ctd\u003e850 watts RMS Linear Class D amplifier with strong peak headroom\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eLow bass reaches deeper with control\u003c\/td\u003e\n\u003ctd\u003e12-inch down-firing Carbon\/Carbon passive radiator and -6 dB extension at 19 Hz\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eThe sub blends with the main speakers\u003c\/td\u003e\n\u003ctd\u003eHigh Level Neutrik Speakon input follows the main amplifier signal\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003eMovie soundtracks gain serious impact\u003c\/td\u003e\n\u003ctd\u003eDedicated LFE RCA and balanced LFE XLR inputs\u003c\/td\u003e\n\u003c\/tr\u003e \u003ctr\u003e\n\u003ctd\u003ePlacement can stay clean in a finished room\u003c\/td\u003e\n\u003ctd\u003eAirShip Direct wireless compatibility, sold separately\u003c\/td\u003e\n\u003c\/tr\u003e \u003c\/tbody\u003e\n\u003c\/table\u003e \u003ch3\u003eTechnical Highlights\u003c\/h3\u003e \u003cul\u003e\n\u003cli\u003e12-inch long-throw CarbonAlloy active driver\u003c\/li\u003e\n\u003cli\u003e12-inch down-firing Carbon\/Carbon passive radiator\u003c\/li\u003e\n\u003cli\u003e850 watts RMS Linear Class D amplifier\u003c\/li\u003e\n\u003cli\u003eLow-frequency extension: -6 dB at 19 Hz\u003c\/li\u003e\n\u003cli\u003eHigh Level Neutrik Speakon, low-level RCA, LFE RCA, and LFE XLR inputs\u003c\/li\u003e\n\u003cli\u003eAirShip Direct wireless compatible, sold separately\u003c\/li\u003e\n\u003cli\u003e19.25 x 16.125 x 21.25 inches; 93.5 lb\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eWhy Choose Audio Two\u003c\/h3\u003e \u003cp\u003eAudio Two ships across Canada.
