The Edifier R1800 BT Speakers are bookshelf speakers that can be connected by either a dual RCA input or through Bluetooth. It has a Class D amplifier and 10-degree angled fronts that help to direct the sound straight to your ears. So, the first impressions is a little mixed, I love the high gloss black body, it is very attractive and looks great on the book shelf, however the front of the speaker lacks any distinction. I think more could have been done here to finish the quality aesthetic off.
