I bought a Warwick Celestion Neodymium 1x12 cabinet 8ohm 400watt cab for my Warwick Quad IV rack. I always used 4x10 cabs (hartke, Warwick, Darkglass...) but holy damn this thing is insane! I don't do gigs anymore because of my illness so a smaller cab was welcome It has so much more bottom and is so thick in the bottom end compared to the Darkglass 4x10! It doesn't fall apart and doesn't have that annoying iron/metal clangy sound in your bass sound. It's just perfect for me! (I rarely play metal btw). I'm a diehard Warwick freak and this cab that I bought for 199€ new at thomann (insane price!) is the best deal that I ever did. The Darkglass was a good cab but this 1x12 blows it completely away.
