Subs are fine. But you still need to dial in the room. What I’ve found is that when a room is treated well everything improves. Otherwise, you’ll have great bass but still have time smear. Don’t think you have it? Everyone has it to some extent. Get the room right and you get to the point where there’s more coherence than smear...achieving that is like finding tighter focus on a camera lens...you wonder how you ever thought what you were listening to before was even listenable. And, everything from top to bottom improves.
Focus, detail, imaging and bass tightness gets very good. Then you add subs. Or like me, you ditch your subs and just enjoy what you have.
How many times have I heard it and never listened: it’s the room...it’s the room...it’s the room. It took something acoustically profound happening to get me to understand it.
