I'm not very knowledgable when it comes to audio equipment... That said some members helped me out in another thread about what I would need as a simple background music system in my kitcken ceiling (must be in ceiling; 15'x20'; 9 ft ceilings) that can be rev-ed up a little if need be...I'll probably just put in 2 speakers...again, not looking for a wow factor...just solid clear music. I'm deciding between RC80i's, TC80i's, and RT-70's (vanishing). Any thoughts? Are the TC's worth the extra $ over the RC's? TC's over RT's?
