DSPPA 20W Miniature satellite coaxial speaker with power tap (Volt&Ohm) | DSP129
The DSPPA DSP129 is a 20 W miniature satellite wall speaker with a 4" coaxial driver. It can run on a 100 V PA line with power taps or on a 16 Ω amplifier output, and it mounts quickly with its bracket.
Key Features
Two ways to connect: On a 100 V line you can choose 10 W or 20 W, and the speaker also has a 16 Ω nominal impedance for low-impedance amplifiers. This lets the same model fit a large paging system or a smaller direct-drive setup.

4" coaxial driver: The 4" paper cone coaxial unit covers 120 Hz to 20 kHz (±3 dB), with a sensitivity of 84 ±2 dB and a maximum SPL of 97 ±2 dB at 1 m. It gives more output than the 10 W DSP118/DSP119 while keeping a compact 148 x 127 x 138 mm housing.
Quick bracket installation: The ABS speaker mounts on its bracket with screws, so it can be installed on a wall without using floor space. The net weight is 1.23 kg.


Who it's for / Works with
DSPPA lists offices, hotels, bars and shopping malls as typical uses for this public address speaker.
Good to know
- DSPPA's datasheet lists the constant-voltage taps for 100 V (10 W / 20 W) and a 16 Ω impedance. 70 V operation appears only in some DSPPA marketing material, so it is not listed here.
- The amplifier is not part of this product: the speaker must be wired with speaker cable to a suitable PA amplifier.
