The speakers work perfectly for regular music listening as well as home theater use. I know several people who, for example, use three KH420s as LCR speakers in the front. The same applies to Genelec and other brands from the studio sector. The mastering engineers who are doing Atmos also use these brands. So... And btw i use a Pair of 150s in the front and kh80 in the back. Its perfect and i can easily drive the system over 100dB at 3m Listening distance (with Subwoofers of course). My best friend has Genelec 8341 with an even bigger room and drive them with even higher SPLs and its totally fun, crystal clear. So, just do it it will be work and is propably even better than any consumer cinema speaker like a klipsch, b&w or similiar
