Hi, I recently purchased a Totem Model 1 Signature centre. I wanted to try it out so I replaced the left side of my Paradigm Studio 20 setup with the centre (used as left speaker) with the other Studio 20 on the right channel. The totem sounds perfect but after about 20 minutes of play the sound instantly lowers and sounds muffled. I immediately turned cut the sound off after that. I tried again and it the same thing happens after every 20 mins or so. What is happening here? I have two different amps (Odyssey Khartago [email protected] and an Outlaw 7125 [email protected]) so both of these should be able to properly handle the totem. What is going on? I hooked the Studio 20's back and they sound fine. No muffling sound after 20 mins.
