The Mackie Thump Series Powered Loudspeakers deliver deep low-end and real power in a lightweight design that is extremely portable. Class-D Fast Recovery amplification pushes unmatched power to the high-frequency compression driver and bass-pounding high-output woofer. Plus, Mackie Active processing, including a precision crossover and driver time-alignment provides total optimization for maximum system efficiency. Versatile by design, Thump loudspeakers feature a user-adjustable 3-band EQ for tone control and, since they can be pole-mounted or used as a wedge, the Thump Series loudspeakers represent the best value available for a complete stage solution.

More than Just a Powered Speaker Cabinet
Sure, Thump loudspeakers have a built-in power amp”in fact, each have two of them. Mackie's 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
For most people, portability is paramount. That's why Thump loudspeakers are ultra-compact and lightweight, especially the TH-12A which is less than two feet tall and weighs in just over 25lbs. For vocal-only scenarios and applications with acoustic instruments that require superior midrange, the TH-12A shines.

Not only are Thump loudspeakers superb PA enclosures, they also make 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. Ultra-wide frequency response makes them ideal as a keyboard, vocal or even bass guitar monitor. Thump loudspeakers have incredibly smooth response and dispersion over a wide range of frequencies, so you can crank 'em up and they still sound smooth and never harsh.

Exceptional Sonic Performance
Thump Series powered loudspeakers put out a tremendous amount of sound for their size and price tag. The 2-way ported design generates ample quantities of chest-pounding bass, and their 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 their 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 Mackie knows you demand the most from your speakers, They added some extra circuitry to keep your Thump loudspeakers 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. Mackie knows 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 safeguards ensure long life and great-sounding loudspeakers you can always count on.
