Both internal amps are designed using Mackie’s legendary Fast Recovery(Trademark) circuitry. Other amplifiers can ‘latch’ when pushed to clipping, leading to distorted audio, but Fast Recovery(Trademark) amplification reacts instantly to the occasional aggressive transient, drastically reducing the time it takes for the amp to recover, ensuring clean audio under the most demanding of situations. This potent bi-amplified system is the highest powered 2-way available in its class, providing a beefy 700W RMS low-frequency amplifier and a 100W RMS high-frequency amplifier that, when combined, can deliver a max SPL up to 135dB (calculated, measured maximum SPL of 125dB). DEFINE THE EXPERIENCE Mackie created the ‘Active’ electronics game long ago, incorporating precision crossovers and transducer time/phase alignment processing into the loudspeaker. This instantly took the guesswork out of setting up a perfectly tuned system and the world of loudspeakers irreversibly changed. HD Series High-Definition Powered Loudspeakers not only advance Active technology, they take it to an entirely new level, marking the next major advancement for powered loudspeakers: High-Definition Live Sound. Even the most expensive loudspeakers on the market have inherent sonic issues that arise from the very nature of loudspeaker design. Horn-loaded drivers tend to have a ‘honkiness’ to them and there are physical resonances in the upper range of cone drivers that can sound nasty. Introducing Mackie High-Definition Audio Processing. The key to high-definition live sound is the detailed measurement and analysis of the inherent problems of horns and woofers. After that, the creation and application of some seriously NASA-esque (and patented) acoustic correction algorithms work to correct these very issues. The resulting experience is not only high-definition, it is truly a moment of clarity for anyone within earshot. EAW INSIDE The Mackie HD1521 is a perfectly tuned system that is truly greater than the sum of its parts. This is only possible due to the hard work and insane genius of the engineering team over at Eastern Acoustic Works (EAW). Not only did they fine tune the system for complete optimization, they also custom-designed the transducers, ensuring maximum efficiency and performance. The high-end 15 inch neodymium woofer features a 3 inch voice coil and is built to handle the massive power delivered by the low-frequency amplifier. The magnet is made using neodymium, which provides a greater magnetic field with far less material. This makes the woofer extremely lightweight without sacrificing one bit of performance. And the large 3 inch voice-coil is built to handle and dissipate far more heat than traditional designs. The 1.75 inch compression driver brilliantly reproduces high-frequencies with a diaphragm made using heat-treated titanium. Heat-treating increases the rigidity of the diaphragm, eliminating nasty distortion that can occur due to inconsistencies on its surface. It also greatly increases the life of the driver, so you can count on stunning high-frequency production for years. TAILOR YOUR TONE For added flexibility, we have included a user-adjustable 3-band EQ on the rear panel of every HD Series loudspeaker. It’s not just a two-position EQ switch that can only bet set to ‘flat’ or ‘boost’, but a high-quality 3-band EQ with Hi and Lo shelving and a sweepable mid frequency, each with +/- 3dB of gain. This allows you to customize the loudspeakers for the task at hand. FIT AND FINISH We could’ve just jammed all these premium components into a flimsy enclosure, slapped on a flashy logo and some plastic end caps and called it a day. That’s what everyone else is doing. However, Mackie has long been dedicated to providing affordable gear that can go toe-to-toe with the most expensive gear on the market and the Mackie HD1521’s all-wood enclosure is no exception. The 15 mm thick birch plywood cabinets are extremely rugged, with substantial internal bracing and a coating of durable, textured black paint. A cold-rolled, powder-coated steel grill provides a sleek, modern look that is designed to blend into the environment. You can even turn off the trademark blue LED on the front of the speaker if stealth is your thing. A work of modern art? Maybe. Rugged and handsome? Absolutely. From backyard BBQs to the most professional install, the Mackie HD1521 can be integrated into any existing system thanks to a wide variety of placement options. Standard M10 eyebolts convert the Mackie HD1521 into a professionally flown system, with twelve integrated fly points for vertical or horizontal rigging. It is also pole mountable, either on a standard tripod or mounted over a subwoofer. And of course you can simply stack them on your subs or place them on stage. Whether stacked, pole-mounted or flown, you can count on the Mackie HD1521 to be stable and sturdy.

Building on the success of the K Series, the KW Series represents the next evolutionary step in wood enclosure loudspeakers. Our system engineers have created the KW Series to feature all the groundbreaking electronic attributes of the popular K Series while at the same time designing a product that is both smaller and significantly lighter than previous wood enclosure models. Features * K Series performance in a lightweight, birch design * 1000 watt Class D power modules in all models (2 x 500 W) * Extensive DSP featuring DEEP™ and Intrinsic Correction™ enhances system performance * DMT™ (Directivity Matched Transition) ensures uniform coverage across the entire sound field * Rugged, texture-painted birch enclosures * Four-position Mic/Line gain (full-range models) * Tour-grade 16 gauge steel grilles * Comfortable ergonomic handles * 35 mm pole sockets with Tilt-Direct™ * M10 rigging points for suspended installation * Also functions as stage monitor High Output Like the K Series, the KW122 features a QSC designed, 1000 watt (2 x 500) Class D power module. And continuing in the K Series tradition, it’s fitted with the identical high-output 1.75-inch HF device and a woofer of the same high quality design, regardless of speaker size. Defined Coverage Area Directivity Matched Transition (DMT™) provides for matched LF and HF coverage across the entire listening area, eliminating unnatural ‘dead’ or ‘hot’ frequency zones. DSP Extensive signal processing is employed throughout, providing levels of sonic clarity and total output that defy all expectations for a product in this category: * Intrinsic Correction™, first featured in our high-end line array products maps 65-75 spatially-averaged measurements to IIR and FIR filters that actively adjust time, frequency and amplitude response to a maximally flat bandpass target. The result is a speaker that behaves equally well across the entire sound field. * DEEP™ and excursion limiting allow for extended low-frequency response by actively managing low-frequency transients without degradation of the underlying signal or adjacent frequencies. * GuardRail™ protection, first introduced on our GX Series amplifiers protects both the amplifier module and your performance from unnatural and destructive clipping. Connectivity The KW122 features a four-position mic / line gain switch that allows for connection of a wide variety of devices. Combo XLR and 1/4-inch TRS inputs accept both mic and line level input while a set of RCA phono inputs allow additional connectivity to portable MP3 players, CD players and line-level mixers. Up to three audio sources can be mixed internally and summed to a balanced output for ‘daisy-chaining’ of multiple units. Separate direct outputs are also provided on each channel for additional output flexibility. Control On-board switches provide preset EQ settings. The HF setting can be set to VOCAL BOOST for additional presence in the critical mid-frequency area or FLAT for accurate reproduction of the incoming signal. The LF switch can be set to NORM, DEEP™ for additional bass extension, or EXT SUB (full-range models) for use with an external subwoofer. The rear panel LED switch can be set to POWER, illuminating the front-mounted LED when the unit is powered on, OFF for applications where it is not desirable to illuminate the front LED, or LIMIT which indicates to the system operator that the clip limiter circuit has been engaged during operation. Tilt-Direct™ The KW122 features a unique Tilt-Direct™ pole cup mounting system. A simple turn of the dial engages a 7.5 degree downward tilt of the speaker allowing acoustic energy to be kept on the audience and off reflective surfaces for applications where maximum coverage from a high-positioned speaker is desired. Remote Gain Remote gain control capability is offered via a potentiometer (not included) connected to the on-board Phoenix-Style connector. In an installed application, multiple KW Series speakers can be ‘daisy-chained’ for total gain control from a single remote pot. Auto-standby mode is engaged after 5 minutes of inactivity. Premium-grade materials The KW Series is designed to withstand the rigours of professional use. Advanced construction processes, premium-grade Baltic birch cabinetry, ergonomic, cast aluminium handles and a highly protective steel grille provide for ease of transport and long term durability. Integrated M10 suspension points allow for flown applications with a KW M10 KIT (sold separately).
