well for music, i do have a subwoofer(8 inch 1000w velodyne), but most of the time I turn it off. I guess deep thunderous base isn't that important to me. I will turn it on depending on the music though because I listen to a wide variety. However for vocals, wind, string, and percussion...it seems to me that bookshelves are (i'm at a loss for words) just sound better. I am sorry but I am not down with the audiophile lingo lol
getting floorstanders to sound right also seems to be very finicky with placement. with bookshelves not so much, but the trick being placing the subwoofer and it adjusting the crossover and phase to the bookshelves and room. I dont have it quite right, i have my brother help me.
