I have both a Splawn 2x12 and a 4x12 and I can tell you they are built like tanks and sound awesome. They're also very affordable and easily found on the used market
I've owed both the Splawn and Bogner OS 2x12. The Bogner OS is in my opinion far better. It is the closest thing tone wise to a 4x12 in a 2x12 format and sounded better that other 4x12's that I owned.
