Anyone had the chance to sit down and compare these two? I'd be getting one or the other with a PF-500, but I have no idea what the difference in sound is between these two cabs. Every thread I've looked at where someone says 15" = beefy lows, 2x10 = fast pop/funk tone immediately gets a ton of replies saying that it always depends on the particular cab, and that generalizations are useless. I'd be using it for a school orchestra and as a home amp. Shouldn't be too heavy (Ashdown combos have caught my eye as well, but they seem to be pretty heavy) as I'd probably have to lug it around a fair bit. Where I live I have absolutely no chance to go and check out what they sound like in a shop. Anyone been down this road? All advice welcome! Thanks!
