Hi Murph - This is good to know. I kinda thought my only option were the M80's due to the room size. Knowing you have a simular space and very happy with the M60's is making me rethink things a bit.
Just so I am clear the M60's in your room fill the space well with sound and don't tend to sound a bit thin on the lower end bass?
We have hardwood floors on all of the main floor, lots of windows and a complete wall of kitchen cabinets. There is not a lot of sound dampening which could make speaker choice and set up challenging. Thoughts?
