Good to know
- This is a passive subwoofer: it needs an external power amplifier (350W – 700W into 4 ohms) and Speakon speaker cables.
- The second Speakon socket is wired in parallel to link another cabinet; mind the total amplifier load.
- The pole (SS3BK) is optional and not included.
FAQ
Does it have a built-in amplifier?
No. The JRX218S is passive and must be driven by a separate power amplifier.
Can I put a speaker on top?
Yes, using an optional 35 mm pole in the top-mounted pole socket.
