Oh yeah! The Scumbacks are worth it. I put some in one my 2 x 12 Recto cabs last February and I love them. They sounded great right out of the box and as they break in they just keep getting better.
I kept a pair of V30s in my other 2 x 12 Recto cab and when I A/B the two cabinets with my Stiletto I am amazed how harsh the V30s sound next to the Scumbacks.
I will eventually sell off all of my V30s and get another pair of Scumbacks.
I am not a V30 hater by any stretch but with the Stiletto it's no contest for me.
If you go to the "Rig Talk" forum and scroll down half way to the Manufacturers Forums section you can look at Jim Seavall's Scumback speaker section and read up too.
