The starting point
Compare an active and a passive PA as complete systems. Confirm where amplification, crossover functions, processing and protection live, then include the required mains distribution, signal and speaker cables, racks and commissioning. The word ‘active’ or ‘passive’ alone does not establish the whole arrangement.
Define what the supplier means by active
In purchasing discussions, ‘active’ often describes a powered cabinet with built-in amplification, but system terminology can vary. An actively crossed-over system may also use external amplification. Ask the supplier to draw the actual signal path and identify the amplifier, crossover and processing functions rather than relying on a category label.
For a powered cabinet, confirm which electronics and protection functions are built in and which settings remain external. For an externally amplified cabinet, request a supported amplifier and processing arrangement for the exact model. Two boxes with similar driver sizes may require very different electronics and operating configurations.
Compare the items the crew must deploy
On a narrow screen, scroll the table horizontally to compare all columns.
| Planning question | Powered cabinet arrangement | Externally amplified arrangement |
|---|---|---|
| Amplification | Located in the cabinet; verify the included electronics | Located in racks or a separate installation |
| Cabling | Audio or network connections plus mains at the cabinet | Amplifier inputs plus speaker cabling to the cabinet |
| Processing | Confirm built-in and external responsibilities | Confirm processor, presets and channel allocation |
| Service planning | Assess cabinet and electronic service access together | Assess cabinets, racks and their connections separately |
Neither column establishes which option is simpler for your work. A touring crew, an installed venue and a distributor can have different transport, spares and access requirements. Include the supporting equipment in the quotation so an apparent cabinet-price saving is not compared with an incomplete system.
Match configuration, control and power
For passive or externally amplified systems, keep the permitted load, channel allocation, speaker cabling and processing limits together. Do not select an amplifier by a universal wattage multiplier. Ask for the documented arrangement supported for the cabinet and the proposed operating mode.
For powered systems, plan mains availability at each location and identify any signal-network requirements. Confirm connectors, operating voltage, control software if used and the behaviour when a link is lost. Have the actual electrical distribution checked for the installation. A mains inlet on a cabinet is only one element of the complete power plan.
Evaluate the whole quotation
Keep coverage and programme requirements in the same comparison. Changing the electronics does not remove the need to design loudspeaker placement, subwoofer integration and any fills or delays. Use a venue plan to decide what the system needs to do, then compare the arrangements that can support it.
- Cabinet models, variants, quantities and intended positions.
- All amplifiers or built-in amplifier configurations.
- Processing presets, supported firmware and protection responsibilities.
- Racks, mains distribution, signal cables and speaker cables.
- Mounting components, transport cases and commissioning scope.
- Service access, troubleshooting information and order-specific support terms.
Bring your existing inventory into the discussion
Send YL the exact models of any cabinets, amplifiers and processors you intend to retain, together with the venue plan and programme. Identify which parts of the proposed system must be compatible with that stock. Ask for an itemised proposal rather than a cabinet-only price. Confirm the accepted model and configuration before treating two quotations as equivalent.
Common questions
Does a powered loudspeaker need no external processing?
Not necessarily. Confirm the functions built into the exact cabinet and the processing still needed to align and control the complete system.
Is a passive system always cheaper?
Compare the complete supplied system, including amplification, processing, cabling, racks and installation. A cabinet-only comparison does not establish the total cost.
