Hello,

I know this is a noob question, but I have only recently started upgrading to serious audio equipment, one component at a time. I recently purchased a pair of M-Audio BX8 D2 monitors, which are connected directly to my PC with a mini stereo jack to dual XLR cable. I would like to connect my Lava LSP10 subwoofer to my setup, and I do not own a sound card and do not plan to purchase one just yet. Each of the monitors is active, and I am not sure what cable I should purchase to do so.

Here is the back of my monitors:

Best picture I could find of the back of my sub:

I would not like to purchase any components besides the cable at the current moment. What should I purchase?

You need a XLR RCA, or 1/4" to RCA adapter. See http://www.monoprice.com/products/search.asp?keyword=xlr+to+rca about 2/3's of the way down. They have them from 1.5 feet, to 50 feet or the XLR to RCA. For the 1/4" to RCA adapter see http://www.monoprice.com/products/search.asp?keyword=rca+to+1%2F4%22 For the RCA cords see http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10218&cs_id=1021814 those come in lengths up to 100 feet.

It is easier to just use the XLR to RCA cords, since you do not have that extra part in there for an adapter.

I see, I'm already using the XLR ports to connect my monitors to mini stereo jack though.

Headphone splitter





Use this, but not this particular one as this is crappy, but this should give you the idea on what to do.


1. Connect Headphone splitter to PC, connect your M-Audio BX8 D2 monitors as they currently are connected, using one of the holes in the headphone splitter.

2. Connect the Headphone to RCA jack to the other hole on the headphone splitter, Connect the RCA end to the subwoofers low level inputs.

Set the PC volume to where you set them, half would be a good starting point. Adjust the Monitors and subwoofers levels to achieved your desired sound. Once this is done, You would need to use the PC volume control to adjust the volume as this would adjust both monitors and subwoofer levels.
