I have two powered monitors connected to a pre-amp right now and would like to know what I would need in general to upgrade that to a 2.1 setup/ add a sub. I’ll be doing this in a month-ish so I want to figure all the stuff out early.
Thanks in advance
Edit:
The speakers are JBL 104’s connected to a Micca Origen (the newest one, I don’t remember the full name).
Take a look at the JBL LSR 310 S, Adam Sub 7 or the Fluid Audio F8S Subwoofer. This is high-quality pro equipment and with XLR a good idea for the long cable paths caused by the subwoofer. Just before the JBL 104 use a Neurik converter. I do not really recommend cheaper subwoofers.
