Hay guys finally i purchased Taga TSW-120, its good, looks very big/bulky in size when i put next to my Taga506 towers, connected to my av receiver, did an auto calibration sounds good, kept the volume to 60% so it could match the towers, sounds good could not spend much time since got recently, was expecting more thundering sound i thing since its new need some time to break through, or not sure if there is any other settings that i have to do... could not audition Polk Psw110 since got an better offer just ordered.
thanks for all your suggestions now i am happy with my complete 5.1 setup.
