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 (4,000–6,000 W into 4 Ω) | LF-3600 4-pole Speakon input |
| System processor / crossover low output | Subwoofer amplifier input |
| Processor high output | Top-cabinet amplifier input |
Setup
- Place the LF-3600 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 4,000–6,000 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 3,600 W continuous, 7,200 W program. Matching A-PLUS amplifiers: A-PLUS VAX 10000 (2 x 4500 W into 4 Ω), A-PLUS VAX 8000 (2 x 4000 W into 4 Ω).

Bigger venues that need more bass output.
Connections
| Connect | To |

| Second Speakon on the first LF-3600 | Speakon input of the second LF-3600 |
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.
