"speaker overpowering the room"
I guess "overpowering the room" depends on individual ears. To my ears, JBL speakers will always overpower the room to listen properly.
In this video, ( JBL 4367 monitor ) JBL sounds are everywhere, except the listening chair. It’s because JBL sounds fill the room 1st and then reaching to the listening chair (center of the room). JBL spkrs fill the room 1st because JBL sounds are backward like almost every other speakers in the world. Some of you listen the sound like JBL for all your life and to them, even the original music sounds weird and distorted. Original music Chantal - Besame Mucho
In this video, Wavetouch speaker (room: 22'L x 13.5'W x 8'H) sounds forward (natural) and never overpower the room even with a powered sub-woofer.
