Summary: This projection sound system was purchased 2 years ago for a large "hard" room (30x40'). Despite repeated tuning, TV and movie dialog always sounded muddled - music and sound effects are great, but dialog is difficult to understand. After 2 years of frustration, the product was moved to a basement theater room - this room is carpeted and is basically a "soft" listening environment.
Summary: I purchased this new sound "Projector" in February, 2010. Sound went completely dead suddenly, and now needs to be sent out for repairs--I could not fix problem using Manual for use. I consider this product both poorly build and unreliable, and I've been buying electronic sound products for 50 years.
