An 8Ohm 1x15 that weighs about as much as a packet of fags, will take 500W, and can be built (loaded) for £250 using just washing up bottles, cereal cartons and sticky backed plastic. What you reckon?
Actually, an 8Ohm 1x15 with similar specs to whatever your 1x12 will be, would be nice.
A slim 2x10 too. And a 2x15. And so it goes on...
Tonally I'd want smooth, deep and without too much unwieldy low end. Do I mean 'tight' - probably. My descriptive words probably mean something different to everyone else. Oh, and the option of a tweeter for those who need them.
Cheers
