How much does having an open wall on one side of your room effect your sub performance. I am asking because we have decided to open put an 8 foot opening in a room that is 12ft x 18 ft. the 8n foot opening will go on the 18ft wall. My setup will be facing going with the long axis of the room.

I recently have been looking into sealed subs due to some recommendations here on the forums. I am about 80-20% music to HT. I know sealed subs tend to work better in smaller places and our room originally was not going to have this large open spot on the wall.

So my question is.... Does this open wall make a significant difference in the rooms acoustics( by the way..the other walls area is about 60% windows.) . Will a ported subs tend to be less boomy in the open room? With the significan amount of windows( which I know are very reflective of sound) be cause to keep with the idea of a sealed sub.

Any guidance would help..
thank.
