DSPPA 20W Rock Waterproof Outdoor Speaker | DSP643G
The DSPPA DSP643G is a landscape garden speaker shaped like a rock, with one 6.5-inch full-range driver and a rated power of 20 W. It has a built-in 70 V / 100 V transformer, so it connects to a constant-voltage public address (PA) system for background music and announcements outdoors.


Rock-shaped resin enclosure: The weatherproof enclosure is made of high-grade resin and looks like a natural rock. It blends into lawns and gardens instead of standing out as a loudspeaker, and weighs 5 kg.
Built-in 70 V / 100 V transformer: DSPPA states that the transformer reduces line losses over long cable runs and allows many speakers to be connected in parallel on one line. This is how large outdoor areas are covered from a single PA amplifier.
Sound output: The speaker has a sensitivity of 87 ± 2 dB (1 W / 1 m), a maximum sound pressure level of 100 ± 2 dB and a frequency response of 100 Hz to 15 kHz, which suits background music and voice paging.
Who it's for / Works with
DSPPA designed it for lawns in schools, parks and plazas, and for outdoor areas such as train stations, shopping malls, parking areas and factories where background music and paging are needed. It works with 70 V / 100 V PA amplifiers.
