Features

Two-Way Speaker Design: The Mackie Thump15 powered loudspeaker features a two-way driver design with a 1.4" titanium dome compression tweeter and 15" high-output woofer. A precision 2-way crossover splits the high and low frequencies between the tweeter and woofer.

1000W Peak Power: The Mackie Thump15 employs an ultra-efficient Class-D amplifier (400W RMS/800W Peak) to drive the woofer for dynamic low frequency response at all volume levels. It also features a traditional Class AB power amplifier (100W RMS/200W Peak) to drive the tweeter for clear high frequency performance.

Rugged Bass Reflex Enclosure: The Thump15's bass reflex enclosure features two front-firing ports for greater efficiency and bigger bass response. The speaker cabinet's rugged polypropylene construction is designed for heavy use.

3-Band EQ: The Mackie Thump15 powered loudspeaker uses a 3-band EQ with sweepable mid to dial in the perfect sound for your application.

• Low EQ: This control provides up to 6dB boost or cut below 80Hz and it is also flat at the center position. This frequency range represents the punch in bass drums, bass guitar, male singers, etc.
• Mid EQ/Mid Frequency: This is a midrange EQ control that provides 6dB of boost or cut centered at any frequency between 100Hz to 8kHz. This Mid EQ circuit is flat (not boost or cut) at the center position. This frequency range includes most vocals (male at the lower end of the range and female at the upper end of the range, plus the fundamentals and harmonics from many instruments.
• Hi EQ: This control give you up to 6dB boost or cut above 12kHz. The circuit is flat (no boost or cut) at the center position. Use it to add sizzle to cymbals, and an overall sense of transparency or edge to keyboards, female vocals, guitars, etc. Turn it down to remove any high frequency hiss.

Level Knob: The level knob adjust the overall signal level at the input to the built-in power amplifier. Thump loudspeakers are designed to operate with a+4 dBu signal when the level knob is at the center position. Thump loudspeakers may accept up to a +20 dBu signal by turning down the level know accordingly.

Mic/Line Combo Input: The input on the Thump15 powered loudspeaker is a combo jack that may accept balanced/unbalanced XLR and 1/4" TRS/TS connections. The input may handle anything from a microphone to a line-level signal such as from a mixer.

XLR Thru Output: This is a male XLR-type connector that produces exactly the same signal that is connected to the input jacks. Use it to daisy-chain several Thump series loudspeaker together off the same signal source.

Overload Indicator: The OL (overload) LED indicator illuminates red when the amplifier in the Thump15 loudspeaker is near the clipping point. It is ok if the OL LED blinks occasionally, because this means that the transient peaks are just reaching the maximum output of the amplifier and your getting the most out of the loudspeaker.

Protection Circuitry: 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. 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.

Mounting Options: Thump series loudspeakers are designed to sit on the floor or stage. They may also be pole-mounted via the built-in socket on the bottom of the cabinet (pole mount or tripod mount sold separately). They are not designed to be suspended.
