Hello,
After reading for months:nerd:, I have decided to build a sub. At first my thoughts were to build an IB sub. But with some concerns of shaking up the roof structures :scared:, and more so after some modeling in WinISD, decided to go with ported sub (for now). Now, which driver to use? I have been eying Dayton RSS390HF4 due to reasonable costs ($159) and good reviews. But then with a little more ... some others could be good contenders. After doing more research I have added Titanik MKIII from Dayton ($179), Mach audio IXL 15.2.2 ($199) and Creative sound Trio12 with 15"passive radiator and 500w amp (all for $379). I have modeled all these on winISD, but have created more questions. I am looking for some help. Thanks in advance.
First, I will start with pictures of the room.
Screen to back wall is 22 feet, side to side is 16 feet. Height on the sides is about 6 ft, in middle at 8 feet. There is about 25 inches depth under the screen and on the sides of the screen. The screen wall is about 10.5 feet wide. the riser in the back is 12 ft x 6 ft, and 8 inch high. I still have to paint the screen (Black Widow  next weekend) and have the carpet installed 2 weeks.
My IB plan was to place the speaker just under the screen with a box enclosure open to the back where it opens to attic space close to 1500 cubic feet and lined completely with icynene. However, now I will likely create a ported enclosure in the same place  under the screen, in the middle, with bottom, back and top attached to the framing structure for added bracing. This bracing may help me get away with single 3/4 inch MDF, and I have to use two layers only on the sides and the front. Also appearance does not have to great other than the front. In addition, this allows me to create a box with up to 1214 cubic feet volume.
I will place the modeling in the next post.
