Hi, first thread on the TB but longtime lurker. So I've recently come into a used Ampeg SVT CL and 410 HE cab on the cheaps. They were sold to me as a pair and the guy said he had been using them as a pair since 2001. I love the tone I'm getting out of this setup, however, I'd like to correct the impedance mismatch (amp is 4 ohms and cab is 8 ohms), but I'm not sure of the best way to go about it. I looked at a 410 HLF but the extra girth in the back prevented it from fitting into my compact car -- myself and another spent a good 20 minutes trying to jigger it in fruitlessly. Here are the options I'm considering. Opinions? 1) Get a 210 AV to stick on top. Arguably the simplest solution (8 ohms + 8 ohms = 4 ohms) but I'm unsure how it will sound and whether or not I'll be able to fit it in next to the 410. 2) Sell the 410 HE and get 2 210 AVs. Would the sound and volume be comparable? I like the idea of having a modular rig since I know I'll be able to transport it. 3) Other cabs. Here is where I just start getting overwhelmed. I've never bought a cab before. I need something the same dimensions as the 410 HE and as close as possible to to its tone (growly but deep), so I'm thinking something 4x10 and sealed, but I need it in the $500 range ($700 is the absolute highest I can go). Used or new, I don't care, but I need something quick because I'm in several bands with fairly consistent gigging schedules. For context my projects all fall into some variation of psychelic/stoner/prog kind of stuff, though I'll be branching out into metal in the near future as well. Hoping for some good replies cause I've just been running in circles in my head for some time now.
