I would have to do some research on tuning frequency and port area etc. Home theater - mid-sized contemporary beige floor home theater idea in London with brown walls. I can use a program that I used for my car audio builds but that is mainly for a basic vented enclosure. Is there an enclosure design that comes to mind that might help me overcome the challenges of the room and allow me to hear and feel the sub frequencies? Also, is there a source for getting an actual design that will allow me to start the build process. I have played with sub placement but most of the positions where it sounds decent, not great, are just not practical. I know I can gain some output on the subs by going with a ported enclosure, not 100% sure if it will be the answer to all of my problems but setting the room up to be sound friendly inst much of an option since I use the room for multiple purposes. Subs are 2 18" Dayton Ultimax, each in 4 cubic foot separate sealed enclosures, each powered by a Dayton SA1000 amplifier. Center channel is a Cerwin Vega xls-215 bi-amped from my Marantz MM7055 Right and left channels are Cerwin Vega XLS-215's powered by an Adcom GFA 555. Open rafter ceiling, open framing, work benches, walls covered in peg board and loaded with tools and other various obstacles that I'm sure are not helping at all. My issue is with the low end, I think I am falling victim to the worst acoustic environment you can imagine. It is all decent gear, nothing to spectacular but sounds good and gets plenty loud for anything above 80hz.
I have a home theater set up in my garage, its basically mix matched components that I sourced from various craigslist and other random purchases. I'm new to the forum but figured someone might be able to point me in the right direction.
