Hi everyone I was wondering is it ok to match demanding M&K speakers like LCR850 or K-series K-17 whit budget receiver like Marantz5300? I know they impedence goes down to 3.3ohms so how will Marantz deal whit it? I dont wont to spend more then 400-500£ on receiver and Marantz looks good for the money but can they drive M&k speak. well? One dillema I have is about crossover, many people say that setting crossover at 80hz will make best HT results but will that make sound little bass-less whit bass coming only from subwoofer? If 80hz is best setting why buy more expensive floor-standing that goes to 40-50hz at expense of mid-bas, tweeter when you are not going to use it?
