I recently purchased myself a new system which includes some Boston A25's and a Denon receiver. Now i'm looking to finish it with a nice and loud wall shake effect sub. The purpose of the sound system is really just for listening to music on fairly loud and a lot of base music is played. I ask for ported as from what I seem to see around that is the best way to go for chest shaking bass? I'm new to all of this so I am still learning!
