Subwoofer and centre speaker recommendations

[Himanshu.Nivsarkar]

I have a NAd 747 AVR and imagine T tower speakers..am looking to add a subwoofer, centre speaker and surround speakers. For subwoofer am thinking PSB 250.Option in PSB for center and surround speaker is limited. Am not sure if imagine XC will be too small for set up..Also I dont want too bulky surround apeakers...Any advise
