LSiC and Denon/Audyssey

I've got a LSi system (LSi7, LSiC, LSifx, and 250 SW), powered by a Denon 3806.

Regardless of how many times I run the AutoEQ for the Audyssey, Audyssey cuts the 250/500 EQ down to -20db, which makes the dialog on movies difficult to listen to. Ultimately I end up using manual EQ, and bypassing Audyssey. Anyone else have this problem?

A related question - when I listen to the test tones generated across the LS7s, the LSifxs and the LSiC, the LSiC sounds very muddy, like it has no top-end. It's wired in-phase, and I know that there's output from the tweeter. But it does behave as if the tweeter is out.

This is regardless if the speakers are set "large" or "small".

Thanks for any clues.

    Welcome Todd.

    It sounds muddy & unclear because a Denon doesn't have the power to handle the LSI series. You need a separate amplifier of at least 200wpc plugged into your Denon to handle the the power properly.

    You are putting your speakers at risk!

    Please do a search here on the forum as this is a widely dicussed topic.

    Actually I will save you the trouble. Read these threads.

    Hi Cathy -

    Thanks. I understand about the need for more power. But this strikes me as an EQ issue. I'm listening at about 30 on the dial - in order to bring out the dialog I've got to bring it to about 10, and still the center is getting overwhelmed by the volume of the other speakers.

    Have you calibrated your speakers with an SPL meter? If not, you shoud do so. Even so, you just might have to run your center channel a little hotter in order to hear it better.

    No SPL meter as of yet. The center channel is running about 5db hotter. I think my more pressing need is to find out why the Audyssey EQ program is dropping the 250/500 by about 20db - it must think that there's a spike in there somewhere.

    Boy - this is old. I ultimately discovered (12 years ago!) that the problem with the LSiC was a blown driver. I ordered a replacement from back then (and still have the center channel).
