Workflow 1: Subwoofer under a pair of PA tops
Live events, DJs and stage sound needing extra low end.
Connections
| Connect | To |
|---|---|
| Power amplifier channel (5,000–7,000 W into 4 Ω) | SUB-221 4-pole Speakon input |
| System processor / crossover low output | Subwoofer amplifier input |
| Processor high output | Top-cabinet amplifier input |
Setup
- Place the SUB-221 on the floor, one per side of the stage or stacked in the centre.
- Split the mixer output through a system processor: low frequencies to the subwoofer amplifier, the rest to the tops.
- Connect the subwoofer amplifier to the 4-pole Speakon input and set its gain for the 5,000–7,000 W into 4 Ω recommendation.
- Check polarity between subwoofer and tops and adjust the crossover until the low end blends evenly.
Tip: Frequency response 20Hz-800Hz; sensitivity 98dbSPL (1w/1 m); power handling 5,000 W continuous, 9,000 W program.

Connections
| Connect | To |

| Amplifier channel | Speakon input of the first SUB-221 |
| Second Speakon on the first SUB-221 | Speakon input of the second SUB-221 |
Setup
- Link the second cabinet from the parallel Speakon socket of the first.
- Two 4 Ω cabinets in parallel present 2 Ω to the amplifier: confirm the amplifier is rated for 2 Ω.
