I need to buy a new amp and cabinet and I looking at matching an Orange Terror Bass 500 amp, which has an output of 500 watts (8 or 4 ohms switchable)with an Orange OBC410 cab, which handles an output of 1,000 watts(8 ohms). Orange tell me it will be a good match but some of the threads here are saying that a 1,000 watt cabinet would not work efficiently with a 500amp head. Can anyone advise please??
