Guys, I have A LOT of WAF at play in my living room. I read you are not supposed to locate a subwoofer under a couch. I get that. My couch is raised off the floor about 3 inches and my IB could stick out the back side of the couch about 3 or 4 inches. My question is; has anyone actually taken measurements using a program like REW to show the negative effects of putting a sub below a couch? Would anyone be willing to show a frequency response graph of their system under every day normal conditions and then with a couch that sits up off the floor a bit placed over it?
Yes, that was the idea. IB located in the crawl space with a the port coming up under the couch. Ideally, I would like to place the IB along the front wall, but my lady will not allow that. The attic is also not an option, and there aren't any alternative ways to set up my living room. I'm stuck with what I have. I certainly do not want to cut a hole in my floor if it will not produce desirable results. I have been moving, aligning, and EQing the two subwoofers I currently have. To give you an idea, both were free and one was found on the side of the road - so they are NOT nice subs. I was able to produce, in my opinion, a decent response curve given the quality of the subs at hand (see attached) and directionality of the bass signal was barely apparent. I placed one along the front wall, and another diagonally across the room NEXT to the sofa. I was afraid to ask a stupid question on here but I couldn't find any actual response curves showing WHY you can't put an IB sub under a raised couch to keep it hidden. In light of this, I think I will err on the safe side and install the IB to the side of the couch and align it with the better free sub on the front wall. The curiosity bug will likely grab hold of me and, if you want to see them, I will post a chart showing the aligned frequency response I was able to get with the IB on the side of the couch vs. the aligned frequency response I was able to get with a couch over the IB - obviously from a controlled listening position.
