Muffled AVIA Surround-Left Test Tone (1 Viewer)

[Roger Kint]

Does anyone have a hissing AVIA test tone on the surround left speaker? It is different from all the other tones and is easily noticeable. My Denon 2802 internal test tones all sound OK, so I can rule out the speaker. BTW, I am using a Monster digital coax from the DVD to the 2802.

Turns out it was the speaker tweeter. The internal test tones are probably limited in frequecies while the AVIA covers a wider/higher freq range. Hopefully Uncles Stereo will replace my 4 mo old M&K SS-150THX spkr.
