The Sweet Spot with 2x10 is not among Allen's standard offering. If that's what you REALLY want, I'd order chassis only, have a custom cabinet made and get 16 Ohm speakers wired parallel. There are lots of cab builders around, I have good experience with Pete Mather and have never read a bad word about his product in this forum. Really good 16 Ohm 10-inch speakers can be had from Dr. Z amps at a very reasonable price - you will need 2 of them wired parallel to get an 8 Ohm load. The Accomplice with 2x10 is a standard offering, but differs in that the PI is a long-tail pair, where the Sweet Spot has a cathodyne PI (following the PR. If you have the time, space, a good soldering station, and a good multimeter, then assembling an Allen amp kit is a very satisfying process if you can decide to be meticulous about your work. I assembled my Sweet Spot in late 2008. I made one minor mistake (wiring of the input jacks) and the amp has been great from then on. Speaker is an Emi Li'l Texas. Sounds great to me and the amp weighs just 28 pounds. With exception of a ground that came loose at the PT, the amp has performed perfectly for 11 years. Meticulous starts with verifying the parts list and measuring to make sure the components are at the expected values.
