Pro Speakers & iSub - including fix
I have both the Pro Speakers and the iSub. I am a home theater/audio aficionado and I know from first hand experience that this combination is greatly underrated and misunderstood by the general public.
Get the iSub and be done with it. You'll love the sound, save a little money and it does look cool -- although I keep mine hiden on the floor below the desk.
The "crackling" that people are commenting about is not the fault of the iSub itself, but rather the iSub's USB connector.
If you hear "crackling" coming from the iSub, do the following:
1. unplug the iSub USB cable
2. turn down the outgoing volume from your computer
3. plug the iSub USB cable back into the computer
4. turn up the volume of the computer, to the level that you like
This will correct the crackling, if it occurs. What is happening is that the wiring doesn't get as good a connection as it needs and it may need to be reseated (unplugged/plugged) a few times before the cables get "burned in".
Good luck and let me know if you have any questions.
Take care,
