Studio CC is only emitting sound from the tweeter. Checked all connections and receiver settings and noticed nothing out of the ordinary. I'm getting no vibration from the cones what so ever. The sound is high pitched and lacks any body or depth. Is these speakers blown or is something else wrong? Any help would be greatly appreciated. Speakers were purchased brand new about two months ago and seldom driven to reference levels. I use the Sony STRV444ES to power my system.
