My little 10" mission m6as used to shake plates in my kitchen at my old place. Now it sounds and feels weak. My ceilings were low and I could close all the doors leading into my lounge room which was perfect . The house I live in now is quite open, it's an old house sorry for the misleading title. Can someone offer some creative placement advice until I can afford to upgrade my sub setup to a DIY 15" or similar? Also, looking at the pics would a 15" DIY be enough to pressurize this space ? I want to shake my plates off the shelves again. My Sub is sitting just behind the left front speaker. Sorry for the mess hehe.
