Like most, have more than one set up.
The one I listen to most is outside on the porch.
My main $$ are in the RedNeck Bar system with my turntable which can't come to the porch.
I have a big sub down there which can break up the muddy breaks. It is the best I have heard, but mostly wasted in that system as Bob's SunFire amps can make the mains sing.
The reason goes to KingMan's question for us to ponder. I like KM.
My mains can cover the bass well with out the sub.
I use 2 Sunfire 600X2. I am not sure of how this configuration would be named, but it produces a good sound. The speakers are 4 ohm.
One Sunfire is split doing duty to the mids and highs of each speaker.
The other is split doing base on each.
As I understand it, that is 2400 watts to the bass and 2400 watts to the rest. I think that is fair as good bass requires some air to move.
The SunFires handle this with ease.
The music is quite good.
