After having an opportunity to demo two local theaters in SE Michigan this weekend, it convinced me that it is time to upgrade the subs in my theater. With that said, I need some guidance on designing the sub that will best fit both my needs and space and also how to pick the best components for the build.
A little background - my theater was finished almost 6 years ago (wow, time really flies when you are having fun). I currently have a 7.2 surround system in a dedicated, sound controlled theater. I currently am running two 15" sealed subs - one in the front behind the AT screen and one in the rear of the theater behind the second row. I am also running transducers in each seat. While I like the system I am currently running, I really would like to increase the low frequency output. I have several questions, but I will start with the basics:
Number of Subs? Options I am considering:
Size of the subs?
- 1 sub in the front, 1 in the rear (current setup)
- 2 subs in the front, 1 in the rear
- 2 subs in the front and 2 in the rear
At the front of my theater, my speakers and sub are all behind the screen. I plan to put the new sub(s) in the same location. I really like the idea of the Full Marty sub or even a Devastator, but space is an issue - mostly when it comes to depth. Because of the frame that supports my AT screen, I only have 20" for depth. This is touching wall to touching frame. I could possibly notch the frame and gain three more inches (but still touching front and back). With that said, I could have two subs that are 35" wide and up to ~70" high and have an inch or two to spare. I am hoping to be able to build something that will perform the same as the Full Marty or Devastator, but with slightly modified dimensions. I really don't know where to begin to calculate the cabinet size and cut sheet.
At the rear of the theater, I want to go a bit smaller because I don't want them sticking above the chairs and don't want to prevent the chairs from reclining. Width isn't a major issue, but height and depth need to be around 20" or less.
Ultimately, I would love to buy a flat pack kit or have a woodworking shop CNC cut the parts, but I also have the equipment to make the cuts myself.
I guess I need to start with these questions first and go from there. Any input would be greatly appreciated.
