Supplier matching
Powered PA speaker quotations need an exact-model file
Portable Pa Speaker Sourcing asks proposed suppliers to tie every powered pa speaker answer to one manufacturer, one model and one included configuration. A family brochure is a starting map, not the evidence file.
Send the venue, the input voltage available on site, and whether the amplifier must run on a battery, a wall outlet, or both. Continuous power should name watts, impedance and the signal used for the rating. A peak number taken at 1 kHz with no crest-factor note is a screening figure, not a factory acceptance test.

Evidence matrix for the proposed powered cabinet
Each cell is a request. The responsible party is the proposed supplier unless you assign a buyer-side reviewer for acceptance.
| Topic | Ask for | Bound to |
|---|---|---|
| Rated power | Continuous watts, impedance in ohms, and the test signal | Exact model and revision |
| Drawing | Height, width, depth in mm, pole cup and handle positions | The same model the price names |
| Acoustics | Frequency response with a ± dB window, maximum SPL at a stated distance and weighting | Test report or datasheet edition |
| Electrical | Input voltage, frequency, phase, current and duty cycle of the amplifier | Nameplate of the proposed unit |
| Compliance file | UL, ETL or FCC documents where the product claims them, plus the model list inside the certificate | Certificate holder and date |
| Serial or batch | How a later shipment will be traced if a driver revision changes | Supplier quality contact |
ISO 9001, when a factory holds it, describes a management system. It does not by itself prove the SPL of one cabinet. Ask which certificate number covers the plant that would build your order, and keep that number beside the model.
Utilities, interfaces and what remains unproven
Can a powered cabinet share a circuit with a mixer and lights?
Write the available input voltage, such as 120 V at 60 Hz, single phase, and the breaker size. Ask for current draw at idle and at the rated output the supplier uses. A 100-240 V autoswitch supply still needs the plug type and the heat it rejects into a closed booth.
Which inputs and processing are actually in the box?
List microphone, line, Bluetooth or networked audio as separate questions. A control interface that needs a phone app is a different commissioning scope from rear-panel knobs. State who supplies the mixer if it is outside the cabinet.
What limits outdoor or balcony use?
Ingress protection, such as an IP54 claim, applies to the tested enclosure. A cover, an open port and a battery door can change the result. Ambient temperature and rain exposure belong in the brief. Noise level at the audience position is a venue limit you set, not a number this site publishes.
A standard powered box can be simpler to document. An application-specific DSP preset, custom grille or alternate transformer may be required when the room, the mounting height or the voltage is unusual. Ask the supplier to split the compliant offer from the specification deviation instead of blending them into one model name. Working envelope for a pole mount is often 2.0 to 2.4 m to the horn; a balcony rail is a different envelope. Throughput of room resets, such as four 20-minute changeovers in a day, belongs in the duty note. Repeatability of a stored preset is a file question, not a performance result. Preventive maintenance is a buyer interval, for example a 90-day driver and battery check. Consumables and the spare parts list stay priced even when the cabinet warranty is 24 months on the supplier’s draft. Noise level limits, such as 85 dBA at the nearest listener, are venue rules. Service access of 500 mm at the rear panel should be in the drawing if the booth is enclosed.
Headline wattage is useful while you build a long list. The opposing review is the stated test basis: distance, weighting, impedance and whether the figure is continuous or peak. Both steps can sit in the same file. Neither step confirms stock.

- US destination and requested timing
- Electrical utilities requirement
- Evidence you already hold, and gaps
- Optional budget with currency and per-unit or whole-order basis
Submit the powered speaker requirement
The form uses the existing inquiry fields. Optional supplier preference means high-end, mid-range, budget-friendly or still undecided. That preference is your buying stance, not a rating we have audited.
