The OSD Nero IWLCR55 in-wall LCR (left, right, center) trimless speaker is an elegant and discreet option for adding left, center, and right speaker channels to a big screen TV. This in-wall LCR speaker can be used as a left, center, or right-channel speaker in a surround-sound system, or as a right or left speaker in a stereo system. The dual Kevlar-cone woofers produce the deepest, full bass tones with smooth mid-frequency roll-off, while the 1" aluminum dome tweeter gives you, a high-clarity, distortion-free sound at the high end. The IW LCR55 is capable of handling up to 160 watts so it can be paired with all AVRs. The two-part mounting system allows you to install the mounting frame and grill before adding the speaker. This keeps dust off the speakers during installation, and custom painting the grills is much easier. For a truly cinematic sound in an aesthetically pleasing, non-intrusive form, the Nero IW LCR55 makes a great choice.
