I’d go with smaller limited range monitors and add sub or subs that you have more control over to fill in low end as needed. That is what I do in my 12x12 room. Kef ls50 metas + klipsch sw308 sub. Sound meter app to get a rough integration using streamed white noise then fine tuned by ear with music. Simple and Perfect! Two subs set up well always better than one but one alone to start may do it depending on how fussy you are.
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.
