Questions buyers ask
What is the best used subwoofer for live sound?
A tested JBL SRX828S is usually the strongest option for output and parts support, provided the drivers are original and the cabinet is structurally sound.
Should I buy one big subwoofer or two smaller ones?
Two smaller cabinets usually give better coverage and easier placement. One large cabinet may suit a fixed install better but is harder to position.
How do I check a used subwoofer before buying?
Ask for driver part numbers, a frequency sweep test and photos of the cone and surround. Confirm the cabinet shows no water damage and that the input connectors are solid.
