12" 2-Way High Definition Powered Loudspeaker

The Mackie SRM1801 18" Powered Subwoofer delivers powerful, chest-thumping lows, perfect for your SRM450v2 PA system. The SRM1801 has a ported bass reflex design that produces tight low end. And the lightweight, ultra-efficient Class-D Fast Recovery™ power amplifier delivers 1000W peak power with less risk of thermal overload. This makes the sub extremely lightweight and portable, without compromising the power and performance that you need. It's the first ever 18" subwoofer specifically designed for use with the best-selling SRM450v2—add some serious low end to your portable PA with the SRM1801.

MAXIMIZE YOUR OUTPUT This potent bi-amplified system is extremely compact (even smaller than the legendary SRM450), but still very powerful, providing a beefy 500W RMS low-frequency amplifier and a 100W RMS high-frequency amplifier that, when combined, can deliver a max SPL up to 133 dB (calculated, measured maximum SPL of 124 dB). There is a lot of debate regarding SPL measurements, and what you see on paper doesn’t always tell the whole story. To forever eliminate confusion and prove that Mackie is dedicated to providing real, testable specs, we have worked up a handy (and somewhat nerdy) guide to the shady world of SPL measurements: Will the Real Maximum SPL Please Stand Up?. Measurements and calculators aside, it only takes one listen to know that the HD1221 delivers more bang for your buck that any other ultra-portable 12" 2-way loudspeaker out there. The HD1221 incorporates the latest in Class-D amplifier technology to deliver a chest-pounding 1200W of peak system power. Both internal amps are designed using Mackie’s legendary Fast Recovery™ circuitry. Other amplifiers can “latch” when pushed to clipping, leading to distorted audio, but Fast Recovery™ 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. 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 “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. Vocals become clean and intelligible and the highs are smooth and never harsh. The resulting experience is not only high-definition, it is truly a moment of clarity for anyone within earshot. FRIENDS WITH BENEFITS EAW LogoThe HD1221 is a perfectly tuned system that is truly greater than the sum of its parts. Mackie benefits from collaborative engineering efforts with the most high-end, professional gear makers out there. For the HD1221, we worked closely with both Eastern Acoustic Works (EAW) and Martin Audio. The engineering team at EAW played a big role in designing this diminutive sonic wonder. They fine-tuned the system for complete optimization and created custom-designed transducers, ensuring maximum efficiency and performance. There’s also an innovative horn design straight from the award-winning engineers at Martin Audio. The high-end 12" neodymium woofer features a 3" 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" voice-coil is built to handle and dissipate far more heat than traditional designs. The 1.75" 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. The HF driver is mounted to a custom-designed 90 x 50 horn by Martin Audio that not only delivers superior performance for its ultra-compact size, it is also user-rotatable by 90-degrees to work best for the application at hand. USER-ADJUSTABLE VOICING The HD1221 delivers professional tone that is easily adjustable to suit the application at hand. On the back, you’ll find a three-position voicing switch which provides the right tone for the job. Leave it in the “Normal” position for standard PA applications. It’s the perfect setting to use when cranking the HD1221 to its optimum volume. The “Contour” position adds a small boost to both the high and low end. This is great for getting the best full-range tone when running at lower levels. And if you’re using the HD1221 as a stage monitor, you’ve got the “Monitor” position, which really lets the vocals cut through a monitor mix while keeping stage rumble and feedback to a minimum. HIGHLY CONFIGURABLE The above acoustic wizardry (more LOTR than Harry Potter) has been engineered to fit into one of the smallest, most portable cabinets on the market. It would have been easy enough to simply jam 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 HD1221’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. These professional features combine to make the HD1221 one of the most versatile boxes around. It can be easily pole-mounted, either directly onto an HD1501 Powered Subwoofer, or atop a standard tripod. If you’re feeling all fancy, there are 12 integrated flypoints for vertical or horizontal rigging. Not enough flexibility? Fine...the cabinet design also makes the HD1221 one of the best stage monitors available...not only due to the specific monitor voicing mode (see above), but also because of the steep asymmetrical design that directs all that sonic goodness at your head, not your belt buckle.
