OK m8, lets start from scratch..
What sub do you intend to purchase & share?
Picking a quality yet cost efficient sub can be the best way to build shares..
What is your budget and what are you interested in and what are your goals?
Before I dig another termonology hole for myself thatfellow whats a sub? To be honest i'm interested in learning more about Linux. It's like the apple bug once it's got you, you'll always be hooked. Although now with Steve Job's gone "R.I.P Steve" not sure what direction there going.
Ok did a search for it sorry, i'm looking to do a multi-room sub in the house just in one room so researching a decent reciever at the moment.
