Here’s a quick look at all the features packed into the TH-15A loudspeakers:
• Flat frequency response (–10 dB, 40 Hz to
20 kHz)
• 1” high-frequency compression driver
• 15” low-frequency woofer
• Convenient portable design, with
integrated handles in both sides and top
• Ported, bass reflex design for enhanced
bass performance
• 99 watt HF and 298 watt LF power
amplifiers (peak)
• Low-frequency over-excursion protection
• High-strength lightweight cabinet
constructed of polypropylene
• High-density adiabatic fiberfill absorbs
internal reflections
• Balanced Mic/Line XLR input and thru
connectors
• 24 dB/octave crossover at 3 kHz
• Adjustable input level control
• LF equalization provides ±15 dB at 80 Hz
and below
• MF equalization provides ±15 dB with
sweepable frequency from 100 Hz to
8 kHz

Introduction
Thank you for choosing the TAPCO TH-15A active loudspeakers. The TAPCO product
line hails back to the days of TAPCO Corporation, Greg Mackie’s first company. TAPCO
revolutionized the audio industry back in 1969 with the very first 6-channel mixer specifically
designed for keyboards and rock ‘n’ roll. In essence, TAPCO redefined the price/
performance ratio and made high-quality professional audio equipment accessible to
virtually anyone. Today, TAPCO shares the same ideals, and is backed by the world-class
engineering and manufacturing horsepower of LOUD Technologies.
The TH-15A active loudspeakers are packed with features and designed to produce
transparent and uncolored sound for PA systems and sound reinforcement. The two-way
bass reflex (ported) design provides an amazingly flat frequency response from 40 Hz to
20 kHz. These versatile compact loudspeakers can be used in a variety of applications,
and when combined with the TAPCO TH-18s active subwoofers, they form an amazing
system. The durable, lightweight enclosure is designed with a socket in the bottom for pole-
mounting on a stand or with the TAPCO TH-18s. In addition, the TH-15A loudspeakers can be
placed on their side for use as floor monitors.
There are many benefits to integrating an active crossover, power amplifiers, and drivers
into a single cabinet, and we’ve taken full advantage of these benefits in the design of the
TH-15A.
• The crossover point is designed so that the high and low-frequency drivers are fed only
the frequencies that they are best able to reproduce.
• The amplifiers are designed to provide maximum acoustic output from the speakers, yet
minimize the danger of speaker damage due to overdriving.
• The length of the connecting wires between the amplifier outputs and the drivers are
kept to an absolute minimum so the damping factor of the amplifier isn’t compromised
by the resistance of long speaker cables.
• The acoustic sum of the outputs from the two drivers are optimized electronically, as well
as physically, so the amplitude response is unity and the phase difference is minimal.
In short, all the complex interconnected components in the system are designed to work
in harmony with each other to produce the best possible sound.
