I'm building my first rig. Currently playing in a very loud Sludge/Doom band, but using my PA (1x18, 2 towers (2x15+horn)) to play bass through. I've settled on either a Carvin BX1500 or Ampeg B-4R for my head unit. Now I need to narrow my choice down for cabinets! It seems like most suggestions go toward custom cabs (Fearful) or very high end brands (Berg, Markbass, etc), but I can't afford those options. My cabinet budget is $400. I live in Idaho, so picking up a super slick deal on a Sunn or Ampeg fridge doesn't happen. The nearest Guitar Center is over 2 hours away. The best advice I always hear is to test it out and see what your ears say, but I can't in my situation. Currently in stock: Peavey 115BX (200w) No BW badges $100-150 Peavey 215D (500w) No BW badge $200 Ampeg BSE 115 (200w) $125-200 Ampeg SVT 115-E (200w) $190-250 Ampeg SVT 215-E (400w) Damaged Tolex, no Speakon $300 Eden D115/D115T (200w) $200 Eden D115XLT (400w) Only 1 in stock $250 SWR Workingman 115T (200w) $200 Hartke 215XL (400w) $300 These models and prices are taken from Guitar Center Used. I'm assuming I'm going to have to run at least 2x15 (2-1x15 cabs). I've heard that 15'' is the gold standard for low tuned heavy metal and I have no experience with 10'' or 12'' bass speakers. I'm open to taking the 4x10 or 2x12 or a mix|match of options if it means getting a better sound for my budget point. My guitarists will eventually be running 50w tube heads into 2-4x12 cabinets. I'll be using some overdrive (Big Muff, Rat). We play in C standard.
