Never before in the history of THX®: Despite the strict requirements regarding dispersion characteristics, the LCR 100-THX was granted the coveted THX Ultra2™ certification for both horizontal and upright operation. Two 17 cm subwoofers as well as the large tweeter cone ensure distortion-free levels up to beyond 110 decibels as well as outstanding purity of sound. The 42 mm tweeter cone runs in an optimally linear way from 1,500 – 27,500 hertz thanks to the installed horn (Waveguide) and sound distribution lens. This helps the LCR 100-THX to achieve a level of efficiency far in excess of 90 decibels. In other words: Even smaller AV receivers make it possible to experience a great cinema feeling with Cinema Ultra. The enclosure of the LCR 100-THX is flat and is perfectly suitable for unobtrusive wall mounting via wall brackets and VESA fittings.
