Yamaha DXR - to sub or not to sub
I'm looking to buy my first PA for DJ'ing after doing a few house parties using some studio monitors which weren't really up to the task. I play dance music - especially classics from the early 90s Renaissance era and I want to be able to play to c.100 people. The just launched Yamaha DXR has great write ups with some reviewers saying that for DJ work they are better than the more expensive DSR range so I'm pretty sold on them - especially as Dolphin music have them with a 16% discount off list.
Details of the speakers are here: http://uk.yamaha.com/en/products/pro...es#tab=feature
My headache is which configuration to go for?
Do I go for a pair of big DXR15s without subs which would cost £1310 or would I be better off with smaller mains - eg DXR8 with matched DSX12 subs - £2216. Budget isn't too much of an issue but I'd appreciate any views on which way to go - is it worth the extra £900 to have a pair of subs. Space / weight isn't really an issue either...
