Nealhood- What is your experience with modified 3.6's? Judging the fact your considering upgrading to them you have NO experience with them and are making very uneducated assumptions on the level of improvements from modifications. Look inside, see what magnepan supplies for components, in stock form you are keeping yourself trapped in the smallest possible space- and yes that is from my real world experience with modified 3.6's in quite a few different configurations.
