Subwoofer boom is too much for me...

No I am not saying a layman should not use subs. I am saying he should learn about subwoofers and their placement and use the great tools available to help him… for instance that great video that explains the physics of placement. They actually have a series.

I used to have four B&W 800 series subs. I no longer have subwoofers in my audio system. I’ve had subwoofers for thirty years. I found them helpful but frustrating to sound right. They did a great job of extending the sound stage but getting them to integrate well was always difficult. I still have two in my home theater… there position is not changeable.
 

I got rid of mine when I upgraded to my Sonus Faber Amati speakers. Could they be enhanced with subwoofers. Sure. But they do well enough for me without subs and I enjoy the perfect coherency across the audio spectrum I get with just the Amatis. 
 

I completely understand why folks like them. The trick is to have the space to set them up and a deep knowledge of the physics.

Subwoofers can be extremely sound quality enhancing. On of the most notable thinks is to extend the sound stage. But proper integration take effort and knowledge. Just indiscriminately fiddling with the volume and crossovers or randomly moving around the room is unlikely to do the job. 
 

I am attaching an outstanding video where professionals discuss sub woofers with the theoretical foundation for sound in a room. Applicable for full range speakers, and subwoofers in a two channel or home theater situation.
