I built 2 dual opposed subs with the 18" dayton drivers. Sounds great. I am currently building a house with a dedicated theater and an AT screen. I was going to put the drivers facing towards the seats. However I could save a bit of room behind the screen if I turned the subs and had the drivers face the side walls. This would be similar to the new hometheater of the month this month. Are there advantages/disadvantages to doing it either way? It would basically save me 5" of room if i turned them sideways. The less sand I need to haul downstairs the better!
