How would you describe the vocals on the other speakers you auditioned? IMO it is important that you find a speaker that gives off the most natural sounding vocals to you because that is what we are most critical of since we communicate on a daily basis as part of our survival.
How often do we hear a live drummer playing in our house or someone playing a trumpet or a strike of a triangle?
You shouldn't worry to much about bass extension with a bookshelf because you can always add a sub. You also seem to like slightly rolled off highs which is a very common loudspeaker preference.
Are you returning the CB20?
I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
