Hi, i have the SVS Ultra Towers, center and bookshelfes with one SB-2000 Pro. \n\nI think the SB-2000 Pro is a solid sub, it packs a punch in the 40-80hz range but i feel like its giving up a bit too early when i crank the volume. The Ultra Towers really impress me, they can play very, very loud and the sub cant really keep up with them. The sub starts lowering the output att around -20 on my Yamaha reciever with certain low Hz rap\/edm songs. The towers cant play as deep of course but they never bomb out before my ears do \n\nShould i go dual? Upgrade to a SB-16 Ultra or even go ported? My usage is mostly music but also some shows, movies and gaming.
