S515 on August 22, 2015 15" Two-way Passive LoudspeakerCLASS-LEADING POWER AND PERFORMANCELoudspeakers are the voice of any PA and Mackie S500 Series Passive Loudspeakers provide the professional power and performance you want for your system. Delivering class-leading power, S500 full-range loudspeakers are available from a highly-portable 2-way 12″ all the way up to a dual 15″ model that can handle up to 2400 watts of peak power. The sound quality is undeniably professional as S500 loudspeakers utilize high-quality components like custom-specified drivers and all-wood enclosures to deliver touring-quality sound in designs that are rugged and affordable. After all, there’s no reason you should sacrifice sound quality for just a few bucks. With a chest-pounding subwoofer and a selection of full-range models, S500 Series Passive Loudspeakers easily outperform anything in their class.BUILD TO BE TOUGH AND SOUND GREATS500 enclosures are real step from those rat-fur-covered passive loudspeakers you find in dingy old venues. They are made of wood which, aside from being sturdy and all-natural, provides the best-possible response, extended low-frequency output without annoying rattles or vibrations. Plus, substantial internal bracing provides a more rigid enclosure, reducing nasty vibrations that could negatively affect sound quality. Lastly, the entire acoustic chamber is air-displaced with adiabatic acoustic batting. This dampens internal midrange reflections so they can’t bleed back through the LF transducer cone and reach your ears, which causes inferior enclosures to sound “boxy.” This, along with LF porting, also allows Mackie S500 enclosures to deliver huge sound in a more compact design than otherwise possible. The full-range S500 models also feature a highly-durable PVC vinyl covering that protects against the occasional ding or spilled drink. They also have protective edge bumpers. If you had roadies, these bumpers would keep them from messing your speakers up when they knock against a door jam or the floor of a beat-up van. The bumpers also have built-in cups for stacking multiple full-range loudspeakers along with sturdy integrated side handles with an ergonomic design that’s great for transportation.HF PROTECTION YOU CAN RELY ONS500 Series full-range models all feature protective circuitry for the HF driver. When the speakers get driven beyond their limits — not that you would ever do that — the HF protection circuitry kicks in and immediately reduces power to the HF driver. There’s a couple of amazing benefits here. For one, you will clearly hear the highs drop in level, effectively signaling that its time turn things down. But the real benefit is that this will protect the HF driver from damage. Once you control the signal, everything will smoothly return to the proper levels. And the show goes on, night after night.DITCH THE CROSSOVERWhen you run a passive system, you want maximum flexibility. Mackie S500 loudspeakers offer a couple of features that can really help out when you need it most. For instance, the S518S 18″ subwoofer features a low-pass filter that strips away all highs and mids, focusing power on low frequencies. This not only lets the sub do what it does best, it also lets you use a single 2-channel power amp to drive a stereo rig without an external crossover, eliminating another piece of expensive gear in the rack.THE VOICE OF YOUR LOUDSPEAKER SYSTEMPassive loudspeaker systems offer an extremely flexible, modular approach that’s perfect for anybody that needs to adapt their sound system for the task at hand or who wants their system to be able to grow over time. The Mackie S500 Series Passive Loudspeakers are the perfect voice for your passive loudspeaker system, with proven performance that is as professional as it is affordable. Pair the S512 or S515 with Mackie’s popular PPM Series Powered Mixer for powerful system that’s easy to transport and set up. Or, integrate with Mackie FRS Series Power Amplifiers and an SP260 Speaker Processor for a completely optimized passive system with the flexibility and performance you need.
