Its a great speaker and the one I listen to most often. I use tube amplifiers at 30 watts and its increased sensitivity allows me to have more headroom. I find the larger horn provides a very large soundstage yet does not create a narrow sweet spot. Tonally its a bit warmer in the upper bass than our smaller speakers. The larger woofer presents the midrange in great detail and does not suffer from beaming. We were lucky to locate a supplier for the 10 inch wide black limba front panel as 8 inches is the size most suppliers carry. The CHR 120 Mark Audio main driver is unique as it does not need baffle step compensation due to a 3 dB rise below 100 Hz.
