Full size speakers WITH subs is the correct answer. There needs to be a sound power hand-off between the sub and speaker. Most subs are far more dynamic than stand mount speakers, so the speaker will still be the limiting factor. There are exceptions of course, TAD comes to mind.
@james633 , Much truth here...Comments like these tend to get buried under the constant misinformation barrage on this forum.
Small speakers like that TAD, Borresen, etc that can manage the ’hand-off’ get rather expensive, much cheaper to go big...makes you wonder why a guy is trying to go with dinky li’l speakers in the first place...i.e., Is he really living in a closet sized room, or is it purely psychological or some other heavy WAF restriction....
