SRM-1801 Mackie Powered Sub
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.

SHAKE, SHAKE, SHAKE THE ROOM
What does 1000W of peak power mean to you? It means having a subwoofer that delivers rump-shaking bass night after night. It means getting class-leading power and output. To accomplish this, the SRM1801 features Class-D Fast Recovery amplification. Class-D amps are more efficient and lightweight, with far less waste heat produced versus competing designs. Fast Recovery means you can occasionally push into clipping without a ton of nasty distortion. So, power is no problem... but how does it sound? The SRM1801 benefits from built-in Active electronics, like a precision crossover and tuning filters for accurate bass response. Some subwoofers have decent power, but when you listen, everything sounds loose and flabby. The SRM1801 delivers professional low end that you can feel...custom tuned to be tight and punchy.

SYSTEM FRIENDLY
Paired with a Mackie SRM450v2 (sold separately), you have a complete (and completely affordable) “plug and play” system that is ideal for small clubs, DJs or rehearsal spaces. The SRM1801 has both full-range and high-pass stereo outputs for connection to full-range top boxes. Just dial in the appropriate level and use the polarity switch to make sure the sub is in phase with the top boxes. The integrated pole-cup can accommodate a standard mounting pole, so your favorite speaker has a nice place to sit. Or you can just stack your full-range box right on top...the SRM1801 ain't picky. It's also a great match for the popular Mackie TH-15A and can easily integrate into nearly any existing PA setup you may have.

TH-15A Mackie Speakers
High-Performance Audio Without the High Price Tag.

Designed by the same team that produced the best-selling Mackie SRM450v2, the Mackie Thump TH-15A delivers deep low-end and real power in a lightweight design that is extremely portable. Class-D Fast Recovery™ amplification pushes 400-watts of power to the high-frequency compression driver and bass-pounding 15″ woofer. Plus, Mackie Active processing, including a precision crossover and driver time-alignment provides total optimization for maximum system efficiency. Versatile by design, the TH-15A features a user-adjustable 3-band EQ for tone control and, since it can be pole-mounted or used as a wedge, the TH-15A represents the best value available for a complete stage solution.

More than Just a Powered Speaker Cabinet
Sure, the TH-15A has a built-in power amp—it has two of them, 300-Watts for the 15" woofer and 100-Watts for the high-frequency compression driver. The Class-D Fast Recovery™ low-frequency amp drives the woofer more efficiently with less heat byproduct than other speakers. But so much more goes into a Mackie loudspeaker design than just amplifiers. Mackie Active technology (based on the popular SRMv2 Series) divides the frequencies via a precision 2-way crossover and also time aligns the signals so low-frequency and high-frequency signals arrive in sync to every member of your audience. Active compression provides a first line of defense for the drivers and thermal circuitry protects the amplifiers and power supply should things get too hot. All the onboard electronic systems work together dynamically to produce superior quality sound previously unavailable in this price range.

Portability Meets Versatility
Not only is the TH-15A a superb PA enclosure, it also makes a superior monitor wedge—just lay the cabinet on its side and turn it up. The compact, lightweight design means zero strain, whether mounting it on a high pole or loading up the van. The TH-15A's wide frequency response makes it ideal as a keyboard, vocal or even bass guitar monitor. The Thump has incredibly smooth response and dispersion over a wide range of frequencies, so you can crank it without the fear of ear-splitting feedback.

Exceptional Sonic Performance
TH-15A powered loudspeakers put out a tremendous amount of sound for their size and price tag. The two-way ported design generates ample quantities of chest-pounding bass, and its 1" compression driver ensures smooth, wide dispersion. Mackie even inserted a 3-band equalizer at the input to give you all the tonal control you could ever want, with an available 15dB boost or cut at 80Hz (low shelf), 100Hz to 8kHz (sweepable mids) and 12kHz (high shelf). With the TH-15A's extremely versatile EQ, you can add some extra thump to that kick drum, bring out the sizzle in your hi-hats, add pop to vocals or correct acoustic anomalies in the room.

Protecting Your Investment
Because we know you demand the most from your speakers, we added some extra circuitry to keep your TH-15As performing at their best, even when pushed really hard for long periods of time. Each driver has its own transparent compression circuit, which helps protect them from damaging transient peaks. An over-excursion filter, inserted just before the low frequency amplifier, protects the woofer from bottoming-out when the low-end is driven to the maximum. This means you can hit them hard without fear of thermal damage. We know things can get pretty hot in the real world, so if the electronics do overheat, separate thermal switches activate and shut down the high and/or low frequency amplifiers until they cool down. These extra protections ensure long life and great-sounding loudspeakers you can always count on.
