All other things being equal, of course. I'm thinking specifically of the TC BG 250-115: http://www.musik-produktiv.ch/tc-electronic-bg-250-115.html versus the TC BG 250-210: http://www.musik-produktiv.ch/tc-electronic-bg-250-210.html The 2x10 costs about 25% more than the 1x15. Is it the loudness of the amp which makes for the price difference? I know there's the preference factor - some people prefer the more 'modern' sound of 2x10s (I'm just going by posts I've read - I have no experience with amps), but if it were just a matter of preference, why would the one be so much more expensive than the other? Lots of people prefer the 1x15 sound. Is there a larger market for the 1x15, and therefore a lower price? I'm confused. Both of these amps are in my price range, but I might be using it for school orchestra gigs, in which case volume might be an issue. Any advice would be appreciated. Thanks in advance!
