Frequently Asked Questions
-
Do I need an amplifier to use this subwoofer?
Yes, the Vonyx SMW18 is a passive subwoofer, which means it requires a suitable external amplifier (compatible with 8 Ohms) to function.
-
Is an external crossover necessary?
It's not strictly necessary thanks to its internal low-pass filter, which automatically cuts high frequencies. However, for more precise control in large professional systems, an external one can be used if desired.
-
Can I connect another speaker to the subwoofer?
The rear panel offers parallel connection options (Link) through its multiple connectors, allowing the signal to be bridged to other speakers if the total impedance allows it.
-
What type of cable should I use?
You can use standard speaker wires with Speakon (NL4) connectors, 6.3mm jacks, or even bare wire directly to the screw terminals.
