Both are 2x12, one has the V-30 the other the Seventy 80 speakers The former is built with tolex covered plywood, the latter tolex covered MDF. The dimensions are very close and the weight is almost the same. I'm looking for an 8 ohm extension speaker for a combo I like and these cabs are the right size to fit under my amp. It is a non-master volume fender with reverb. On an ergonomic standpoint, the ORI212A has an interesting slanted angle to the grab bar of the handle. Not that I'll be moving it much but if i were to start gigging, or even going to jams that might make it easier if the design is actually useful. The vintage snob in me likes the look of the SV212, but I'm having a real hard time swallowing that 799.99 price tag while the ORI212A is less than half at 299.99 I'm not looking to change speakers to get a sound I like better. I want to buy and be done with it. I want a good full sound and while I would love love love to have a 4x12, space and money are not infinite in my universe. Anybody out there have experience with the two of these? I'd love to hear from you.
