To your original question, To me you wasted your money on the 11's. I auditioned all the monitors and I ended up buying the 7's. It would have been $200 more for the 9's and another $200 more for the 11's. All three of these speakers are within a couple of db's so you can see the waste of money you are wasting on the 9's or 11's over the 7's. If you were not going to stop at the 7's your money would have been better spent on the studio 20's or 40's. Now all five of these speakers I have mentioned are going to have to be complimented with a sub anyways so you can see that the 9's and 11's are not worth the extra $. This does not mean the 9's and 11's are no good, it just means that they are not worth the extra $. When I broke my speakers in, about the 5-10 hour mark the woofers really started thumping lower and lower. I even tricked my wife into thinking the sub was on when it wasn't. My 7's hit low but for my tastes, not low enough. I need my sub on aswell. In the past I have taken paradigm speakers back and I had no problem getting my money back. I went 6.1 once so I got a center rear, I did not like it so I returned them and got two center rear speakers, I did not like that either so they gave me my money back. But also I have bought alot of paradigms in the past so I do get treated good. I know of the bi-amping feature on your 3805 but just so you know that something isn't wired backwards, just hook them up directly the normal way and also do not bi-wire either. Make sure you put your jumpers back on. If they don't start to pound and you have fiddled with the placement, I would take them back and tell them you are very dissapointed with the bass performence and you would like to get the 7's, 20's or 40's. With the 20's and 40's you will have the added cost of stands. When you do listen to the 11's again make sure you listen to them in pure direct.
