Hi everyone!

I'm trying to add a subwoofer to my current 2.0 setup. I'm thinking on buying Polk PSW10, as per the reviews I've checked it's a pretty decent quality per dollar spent device and I can't blow my house so that should be enough.

I'm a Tech House and Techno DJ and usually practice and record sessions in my room so I'm looking for a bit more of projection in the low end, I don't think I can achieve that by upgrading my 2.0 system so want to include a sub into the family, I'm having some questions when it comes to connections.


My 2.0 system has one active speaker with a speaker cable output which goes to another passive speaker also it has 2 RCA inputs, one is currently connected from my PC 3.5 jack to RCA terminal, no outputs from the speakers. If i would like to add this subwoofer to the system, what would be the best way ?

I'm thinking on getting a 3.5 to RCA from my soundcard C/SW output to the subwoofer line input then another cable from the L/R speaker output in my soundcard to the speakers. Would this be fine with that subwoofer? I can equalize the speakers to get some better highs/mids once the sub is on.


Also my DJ controller has a TRS balanced master output, a RCA unbalanced master output and a RCA balanced booth output, how can I manage to connect all to the new '2.1' setup? Should split the master output into RCA's to both the sub line in and the speakers input ?

I don't see any logical challenges in doing so, but I'm talking from the inexperience here. Let me know what are your thoughts.

Regards,
 
Hooking up the sub is just what you suggest.
Green analog out to your monitors.
Orange analog out to you subwoofer ( Make sure not to use the center channel)
You can connect the subwoofer out to either the left or right input.
Set the PC to 2.1.
Start with the frequency on the back of the sub full clockwise to let the PC do the high pass to the sats and low pass to the sub. You can play with it if needed later, Leave the level control at 12 o'clock unless you don't have enough gain to adjust the level on the PC to balance with the monitors.
With the DJ controller you won't have a high pass for the monitors so you won't be able to optimize it as well.
