I'm considering getting the base 12" sub from Rythmik, I don't have a lot of space for anything else unless i just build a pair of cheap 8" DIY subs, unless I can find a matching Logitech Z4 sub where the shipping isn't the same as (or more than) the unit itself... :p
If im lucky, I might be able to steal the one from my mother since its a matching unit. Just not sure if the Sprout allows for speaker outs at the same time as RCA outs... Should probably check that first..
Being stuck in a 10'×12' room & desk setup really limits my options, tbh, much as I'd want something more interesting. But its fine for now.
