I bought one of the discontinued DSW 4000 subs from the Polk ebay site and a new center channel CSi A6. I hooked it up yesterday and was disappointed with the output (don't know what I'm doing) until I ran the auto calibration.
While it's running the auto calibration it sends out test tones that rattle the house like nothing I or my family have ever experienced before. I'm in the basement and kids were two stories up in a 5200 sq. ft house and they were terrified wondering what was going on. Then after running the sub calibration test I re-ran the receiver auto calibration test, not sure if I was supposed to do this or not.
After the sub auto calibration I knew it had some serious power but couldn't figure out why I can't get it to work this way with sample music I was playing or in Uncharted 2 on the PS3. I'm using the LFE signal and as I played PS3 for some time the sub seemed to get better but nothing like the auto cal test.
I need to figure out how to access what this sub has to offer (or maybe its the signal I'm sending to it??). I tried the different settings on the remote for sub placement and phase control, just wish the remote worked.
It has a remote control, worst thing ever. My kids barbie house has a better remote control. I can't get it to work unless I'm within 4 feet of the sub, I'm even looking down the remote like aiming a rifle to make sure I'm hitting the little window on the sub. What a piece of crap. I might look into the IR repeater thing but not sure if I feel like spending half a day figuring out what I need to buy to make that work. Maybe Polk could put some part numbers in the manual on suggested IR repeaters.
From an Industrial Design point of view Polk nailed it on this sub. It looks great, smooth corners and lines all in a finish rivaling the bathroom mirror. Amazing to me how much time Polk spent on the appearance of this product but obviously no time on the remote control. Sort of like Audi cars, look incredible but lacking in the technical functional area.
Onto the center channel CSi A6, this is an excellent item to have as it makes my entire home theater system come alive. You really want one of these, actually, you NEED one of these.
So I think I need to learn more about subwoofers to make the 4000 work like it should. Here's all the other stuff I'm running (maybe some of this is the problem?????)

TV: sony 52" 800 model w/internet
