OUR PART # TH-15A
The Mackie Thump TH-15A delivers deep low-end and real power in a lightweight design that is very portable. Class-D Fast Recovery? amplification pushes 400-watts of power to the high-frequency compression driver and 15" woofer. Mackie Active processing, including a precision crossover and driver time-alignment, provides total optimization for maximum system efficiency. The TH-15A features a user-adjustable 3-band EQ for tone control and can be pole-mounted or used as a wedge.
The TH-15A has 2 built-in power amps - 300 W for the 15" woofer and 100 W for the high-frequency compression driver. Mackie's 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.
The compact, lightweight design means zero strain, whether mounting it on a high pole, turning it on its side to use as a wedge, or loading it into the van. The TH-15A's wide frequency response makes it ideal as a keyboard, vocal or even bass guitar monitor. The Thump has smooth response and dispersion over a wide range of frequencies, so you can crank it without fearing any sudden rise in feedback.
TH-15A powered loudspeakers put out a tremendous amount of sound for their size. The two-way ported design generates ample quantities of chest-pounding bass, and its 1" compression driver ensures smooth, wide dispersion. A 3-band equalizer has been installed at the input to give you tonal control with an available 15dB boost or cut at 80Hz (low shelf), 100Hz to 8kHz (sweepable mids) and 12kHz (high shelf).
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. 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.
