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.

More than Just a Powered Speaker Cabinet
The TH-15A has two built-in power amps, 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. 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 on-board 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. We 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
Added circuitry keeps 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. 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.
