My room is smaller than yours, I had massive ( walls shaking furniture vibrating, speakers in sympathetic coupling) bass problems until I added two subwoofers. I now use these two with Audio Physic floor standers. The problems have disappeared and the sound and balance is fantastic. Soundstage and depth is exceptional. I use a MiniDSP with bass cut to the main speakers at 60Hz, and the room bass node frequencies cut. Very against putting DSP in my system, problem is it works. Benefits of a better controlled bass are obvious however the main speakers are much less stressed, the subs do the hard lifting and I can place them to best advantage. I have a tube hybrid power amp that works in Class A up to 10 watts. I doubt if, in this configuration, it every puts out more than 1 watt.
Am I Better Off With Limited Low Frequency Speaker In A Small Room?
In my 12'x12'x11' room, am I better off with limited low frequency speakers, such as those which only extend down to 40-50hz, or will the mere introduction of a speaker that extends down to 35hz be potential for trouble (The extent of my knowledge is that lower frequencies need larger spaces to truly breathe, and the wavelength goes up exponentially). My listening space is my living room, and there's not a lot of space for room treament. I'm auditioning a single GIK Soffit bass trap. I'm not sure how much it will help.
