Adding a Second Sub


I am debating buying a second sub to have stereo subs. I have Sonus Faber Extremas and a Rel Stentor. I would really like to hear from people that have done this and what they thought of it. Were there any drawbacks? What were the advantages? Did it make a huge difference?

If you are crossing over low enough, then you don't need two subs for stereo as Faberryman and others have pointed out. But two subs often gives a better result - the main reason being that you can get smoother response. Some subs use two drivers, one on each side, and their separation by a foot or so helps to get a smoother response. It is just that each driver will create room nodes and anti-nodes in different spots and (hopefully) cancel each other out. The downside is that set-up requires even more patience and time than with one sub. From experience you will very likely get a significant improvement with two subs, but two Stentors is a big investment in the bottom octave.
I started my first system with Aerial 7's...added one Vandersteen 2W...wow, what a change! BUT, the most noticeable change was not in the bass range, but how the 7's opened up and became more dynamic. Subsequently, I added another 2W, and BAM, once again a step up in the performance of the 7's...Take out one sub and its like a v-8 running on 6 cylinders...I vote for two subs.
two subs will improve *all* aspects of a two-channel stereo system - better room-integration, better soundstage, less distortion for the same wolume level. go for it! :>)
