To have a really good theater experience in your home you have to have a subwoofer. No doubt about it. So what should you look for when you are looking to add a sub to your home setup? The first is to decide on whether you want an active or passive sub. An active sub has a built in amplifier which means you don't have to power it off your main amp and can dedicate those channels to your full range speakers. A passive sub is exactly what the name implies. A subwoofer without an internal amplifier requiring an external amplification source. What else should we consider for our subwoofer purchase? Like with all speaker purchases everyone has their own preference when it comes to sound quality, but the following should help you interpet what you are hearing.
