The HTM61 and 62 incorporate the latest B&W loudspeaker technology for the 600 series. They incorporate B&W's "FST" technology and how it improves the issue of standing waves in the center of the mid-range drivers, shorter signal path between tweeter and drivers and cross-over components, etc. I have the HTM61 and it is fabulous for the price. Great for voice reproduction in movies but also don't forget it also reproduces music in both films and audio. Suggest you read about FST technology at B&W's website for the 600 series. Much improved over the LCR600 as Tesseract86 states.
