The DSPPA DSP1650 is a 50W outdoor horn speaker with an IP66 rating, an ABS horn and a metal bracket. It runs on a 100V line with 6 to 50W taps or direct at 8 ohms, and suits school yards, car parks and warehouses.
====
The DSPPA DSP1650 is a 50W outdoor horn speaker for paging in open areas exposed to dust, sun and rain. It reaches 123dB at one meter, carries an IP66 rating, and connects to a 100V line through selectable taps or directly to an 8 ohm amplifier output. School yards, car parks, loading bays and farm compounds are the kind of spaces it is built to cover.
DSPPA DSP1650 key specifications
All figures below come from DSPPA's official product page and datasheet:
- Rated power: 50W, with taps at 6, 12.5, 25 and 50W.
- Sensitivity: 106 ±2dB; maximum SPL: 123 ±2dB.
- Frequency response: 280Hz to 4.5kHz, a range tuned for speech.
- Protection: IP66 against dust and powerful water jets.
- Size and weight: 404 × 266 × 376mm, 4.2kg.
Power taps let you set each speaker's level
On a 100V system the tap decides how many watts the speaker draws from the amplifier. Run it at 50W over a large yard or an open car park, and drop to 6 or 12.5W near offices or entrances where full volume would be too much. The taps also make load planning simple: add up the tap settings on a line and keep the total below the amplifier rating. If your amplifier has an 8 ohm output instead, the DSP1650 connects to it directly.
Built for outdoor installation
The horn is ABS and the bracket is metal. IP66 means the unit is dust-tight and handles strong water jets from any direction. DSPPA rates it for -20 to +40°C, so on sites with full summer sun a partly shaded mounting point is the safer choice.
Typical uses in Saudi Arabia
- School yards: morning assembly calls and school broadcasts outside the classrooms.
- Mall and compound car parks: general announcements over open parking areas.
- Warehouses and loading bays: calling drivers and staff over equipment noise.
- Farms and large rest houses: covering wide outdoor areas with only a few speakers.
- Factories and workshops: shift-change announcements and alerts.
Amplifier compatibility
The DSP1650 works with any mixer or power amplifier that has a 70V or 100V output. A quick example: six speakers on the 50W tap draw 300W, so choose an amplifier rated above that with some headroom. Wire the speakers in parallel using speaker cable sized for the run length.
DSP1650, DSP1130 or DSP204H?
The DSP1130 belongs to the same weatherproof family at 30W, which makes it the better fit for smaller areas. The DSP204H is a different product: an explosion-proof horn marked Ex db IIC T6 Gb, rated 30W and IP65, weighing 7kg, with a 400Hz to 10kHz range. Pick the DSP1650 for standard sites that need more output (50W, IP66, 4.2kg) and keep the DSP204H for areas where flammable gas may be present.
Frequently Asked Questions
Does the DSP1650 need a special amplifier?
No. It works with any amplifier that has a 70V or 100V output using the taps, or directly with an 8 ohm output.
Can it handle rain and dust?
Yes. DSPPA rates it IP66 and designs it for outdoor installation.
How many DSP1650 speakers can a 350W amplifier drive?
Six on the 50W tap (300W total) or up to twelve on the 25W tap (300W), leaving some headroom on the amplifier.
