I am about to take delivery of a custom built Amplified Nation Dumble/Two Rock monster that's basically a really dirty 100 watt Steel String Singer. I was going to have AN build me a matching unloaded 4x10 oval back cab that I would load my older Celestion G10S-50 speakers into. This would cost me about $500 since I already have the speakers. I love 4x10 Fender combos so that made me want a 4x10. The issue with this is that it might not be ready for a big run of gigs I'm doing right after the head is delivered if I start it now and I might not be able to wire up the speakers in time to use it (I don't know how to do that stuff at all). The other option is to grab a Marshall Handwired 4x12 slant cab and replace two of the Greenbacks with Cerwin Vegas. I love these speakers and that's kind of the Duane set up, who is my favorite player. It might give the AN amp a little more meat and grit too. The 4x12 really isn't much bigger than the 4x10 and if I ever want the 4x10 the 4x12 is an easier resale item. I just am not sure if the closed back will work well for what I want, however I just spent a day with JD Simo playing through his '68 Plexi full stack and it got me back on more of a Marshally kick so maybe the closed back Marshall cab will give me the best of both worlds- Marshally grunt with smooth Dumble drive and reverb. I am supposed to take delivery of the amp on Friday the 10th and have a gig with Kofi and Oteil Burbridge on either the 10th or the 11th, one on the 12th, the 14th with Butch Trucks, and then I go away to play Wanee festival for the rest of the week, so I need to make this decision now and I can't have something I'm not happy with for a week and a half of HUGE gigs for me.
