The CVP-121 and CVP-118 are equipped with Speakon
®
NL4 inputs and the CVP-118 has additional 1/4” inputs. The usual
method to using a subwoofer is to send your mixer output into an electronic crossover, which separates high and low
frequencies. The low frequency output of the crossover is then sent to the input of the power amplifier designated for the
subwoofer. Depending on the speaker output jacks on the power amplifier, connect the subwoofer using a cable with
either Speakon connectors or 1/4” jacks (CVP-118 only). You can also connect the subwoofers without an electronic
crossover.
Connecting Two Speakers: Since all inputs on a Cerwin-Vega passive subwoofer are wired in parallel, it is
possible to connect two speakers by connecting the output of the powered amplifier to one input, and a
second subwoofer to the other. Each subwoofer is a 4 ohm load. If you connect two subwoofers, the load
becomes 2 ohms.
