What the AI looks for in Stage Subwoofers
- Driver size
- 12 inches for portable small-room setups. 15–18 inches for big rooms, dance music and outdoors. Larger drivers and cabinets move more air and extend deeper.
- Crossover and high-pass outputs
- Look for a sub with high-passed outputs to feed the tops. Routing bass to the sub frees the tops from low frequencies, so they play louder and cleaner.
- Pole socket
- Check for a threaded M20 socket or a 35 mm cup so the tops can mount on the sub. This saves stands and floor space and keeps the stack stable.
- Polarity and cardioid options
- Polarity, delay or cardioid settings help in reverberant rooms and on loud stages. These settings reduce bass on stage and keep the low end tight.
- Weight and casters
- Check the cabinet weight and whether it has casters before buying an 18-inch model. Big subs are hard to move without wheels and help.
Brands that matter
- QSC: KS series powered subs that pair with K.2 speakers.
- Electro-Voice: EKX and ELX powered subwoofers.
- JBL: EON and PRX powered subwoofers.
- Yamaha: DXS series subs that match DBR/DZR speakers.
- RCF: Strong-output Italian powered subwoofers.
What to avoid
- Home theater subwoofers used for live PA.
- Subs without high-pass outputs or with weak controls.
- Undersized 10-inch subs sold as 'PA subwoofers' for full bands.
Questions
Do I need a sub for a live band?
For acoustic or speech gigs, often not. For kick drum, bass guitar and DJ music, a sub adds low end and lets the tops play cleaner.
