I am looking to take advantage of further discounts offered by buying floor model speakers. I am concerned that since they have been on the showroom floor two years they may have been beat up by playing too loud or have too much use already to make it worth the extra savings. Even though the full mfg warrenty is offered I am still cautious. The speakers I am looking at is definitive technology, BP30s or BP2002tls. What are your thoughts/experiences on buying floor models?
