A cab is more than just the sum of the speakers put in it. Dimensions, bracing, porting, materials, crossovers....all go a long way to giving the final tone. Then of course fashion enters the mix, personally I bought my 4 x 12 from the factory in Essex not only because I loved the sound of it but because it was green
I have to agree with a lot of the other posts though, I haven't seen TE gear go for reasonable money in a considerable time....personally I think the (IMO) rubbish they put out after leaving these shores has damaged the resale value and name. Although some demos of the brand new models sound like a definite step in the right direction.
