One of my neighbors is all AR, 6.1 using Hi Res line and the Big Hi Res sub. Brett would know the model # of the sub....
Sunfire powered.
Sounds nice even being drive with his Pioneer Elite...Not a big Pioneer fan... A little to forward for me though and the Pioneer most likely dose not help in this area.
I do think there are "many" more lurking here that run AR and just don't post about them.
