Brand New REL S5 Subwoofer for sale
Color: Piano Gloss Black
Inside the S/5 is a new forward-firing 12" alloy-cone woofer. Additionally, there’s a downward-firing 12" passive driver with a unique carbon diaphragm that is similarly stiff and lightweight. REL says that the S/5 uses a simple filter-type that’s quite fast—with about eight milliseconds in group delay—to eliminate the passage of unwanted higher frequencies to the REL driver. The S/5 now uses a NextGen2 550W switching amplifier that can generate up to 873W on hard transients. Per tradition, REL subs do not use high-pass filters—the main speakers run full-range, full-time. REL’s view is that high-passing the sub/sat looks good on paper, as it allows the main speakers to perform with less stress and more dynamism. But REL also believes that high-pass filtration creates more problems than it solves. Why? Because the main speakers are designed and voiced to operate within a specific range of frequencies, and by cleaving away a portion of that output via a high-pass crossover you are essentially refashioning the speaker into a different, even unpredictable unit never contemplated by its designer. That’s why—at least under their breath—many designers don’t actively embrace third-party subs, high-pass or not. Subwoofers from the same brand are another story. They have purposefully designed drivers and low- and high-pass crossovers to pair with designated models (Revel, among others, comes immediately to mind as a specialist in these matters). In any case, no high-pass filtering for the S/5. The back panel houses a phase toggle and rotary settings for the low-frequency effects (LFE) level and for volume, plus the tiniest 39-step increments for adjusting the crossover over the range of 30–120Hz. There are dual low-level RCA inputs, plus an LFE input, but the high-level input is and has always been REL’s preferred means of installation. A lengthy Neutrik connector is provided for this purpose. It carries within its jacket four wires for connection to an amplifier’s speaker taps. REL suggests starting with corner placement, usually on a room diagonal. This not only maximizes room gain but also allows “for the most linear true low bass wavelaunch.” The set-up manual REL provides is quite comprehensive (without being intimidating) about optimizing placement. In my experience, dialing in an REL is a matter of a few easygoing minutes rather than hours of hand-wringing. My advice: Bring a friend for fine adjustments.
