Speaker Help Needed

[DarthBork]

Hi there, I've recently bought a pair of Q acoustics 1050s, and an Onkyo 605. Prior to this I had Logitechs Z-5400 surrounds, which I was fairly pleased with. With the addition of HD audio and a beefier set of speakers I was hoping there would be some improvement. However the speakers perform poorly, give a strange muffled sound that even my computer speakers could rival in the high end. There must be something I've done wrong, because both speakers do the same thing. So it can't be a defect. As of late, I've noticed the Tweeter doesn't produce any sound which is probably the root of the problem. I've wondered if they arn't on full band, but surely that shouldn't change whether the tweeter should work or not.

Here's the way I've wired them:



If I wire them any other way they produce no sound, other than the top two, which produce a very high pitch soundtrack from the movie.

Any help would be greatly appreciated. Thanks. Loui.
