I recently purchased a 5.1 set from Newegg from Definitive Technology. It got really good reviews, and only cost about 220 so I jumped on it.
I have a brand new Pioneer VSX 1122-k.
I hooked up all the speakers and the sub and ran MCACC. It couldn't find the subwoofer. When I set it to yes anyway it said it was turned too low.
I'm using a cable I purchased from bestbuy that I believe was labeled "subwoofer cable" it has 2 male purple ends. I simply stuck one end into sub pre-out 1 and one into LFE. I tried a RCA cable, only plugging one color into the sub pre-out 1 and the LFE. Still got nothing.
I then took my L speaker's wire and put that into the input terminals on the subwoofer to see if that would work, because I know the speaker is working. Still got nothing.
I should also mention that when I plug in and unplug the sub I don't hear the audible thump that I'm used to when subs power on.
At this point I THINK it's the subwoofer but I really don't know. I haven't been able to get any sound out of the sub pre-out. I tried using one color of an RCA cable into the sub pre-out and into a set of bookshelf speakers that I know work.
Any advice would be really appreciated. I'm at my wits end, and only want to spend the 50$ to ship it back for a replacement if I'm absolutely sure it's the sub.
