I'm a little confused. I've got a Peavey 2x10 that's rated at 175w RMS, which I'm thinking of using as a separate cab (it's powered by a combo atm), possibly with another Peavey 2x10. I can get a 2x10 cab for a similar price over here in the UK that has 2 Emience 300watt RMS 10" drivers, so overall a 600watt RMS cab, same price, same size, slightly lighter. As far as I can tell, Peavey are the only manufacturer of 2x10 cabs rated less than 200watts RMS, why is this? Their 4x10 is rated at 350watts RMS, which seems like a logical step, but their 8x10 is rated at only 400watts RMS. I can't get my head round this, do I buy another 2x10 and whack 300 watts into each, or sell up and get something with more power? Lastly, does anyone know how efficient these cabs are?
