Welcome Nick,
As the others have stated, the m60's can be driven easily by most receivers, they are very efficient and sound great. I have the Denon 2805 and love the sound it makes with my M60's. It also has a crossover setting, which I place to 80hz, this is for all speakers. Any low freq's below 80hz gets rerouted to the sub channel. Many receivers allow you to adjust each individual speaker, as some speakers can play lower than others. Try to find a receiver that has all the bells and whistles you want, and one that is easy to operate. Denon's can be a little hard at first...
