Brian_32 :
I have audioengine 5a+ speakers. I have them set up to my computer and they were easy to set up and sound great. I am not sure however where and how to set up my audioengine subwoofer to make it also play in sync with my speakers. What cables should i use? What outputs and inputs are involved? (both on the PC and speakers subwoofers)
The best way is to connect the subwoofer to the audio out on the primary A5 speaker. The A5s work great full range. You can use the volume on the speaker or remote, and then you can leave the computer volume full for less noise, besides many websites that use Flash will maximize the Windows volume anyway. One of the biggest Microsoft screw ups.
I actually have a similar setup though I used a B&W sub. Sound incredible, be sure to set the phase switch correctly and fine tune the crossover point. 50HZ is where I have set mine and works well.
Hope you don't live in an apartment.
