Hi,
I just picked up a pair of Infinity RS4001 3-way speakers. I am not getting any sound from the sub it seems. At first it sounded like they were under powered, but I think it is actually that the sub is just not working. I tried connecting it from an Onkyo A-9110 and an older Onkyo A-807 with the same results from both. I am pretty new to learning about audio systems. Any advice is appreciated, thanks in advance!
