Yep, well integrated bass that is quick and tight and something that will play low (25hz) is a game changer. It adds so much to the music including the mids, highs and soudstage. Theres quite a bit of music that benefits from a sub, even in the midrange. There are times were a solo vocalist has tones that go really low. Somegimes it might just be that they blew into a mic to hard but it actually adds to the music. Its hard to explain but once you here the bass in parts of the music, you can't unhear them.
Finally Learned: Subs serve much larger role than adding more low bass
I sold my older powered sub a while back. reasons-
1. It did not integrate well.
2. I was pretty satisfied with my 2 speakers bass output.
3. Was big, heavy and ugly.
After traveling around the counrty and listening to home systems put together by people who know their way around the industry I realized they all have something I did not. A well integrated bass array.
So what does a bass array add to a 2.0 system?
This is where words fail but I will try:
-Increased Involvement in the listening experience
-More enjoayble sound stage
So if you are like I was, a sub denier, I suggest you try one small
sub, as I did, and see what you experience. My $500 REL T5x experience
did it for me. Now I will buy a second one.
