Short answer: the PreSonus Eris Studio 8 for a less fatiguing listen, the KEF LSX II LT for dispersion. The Eris Studio 8 is more natural sounding and less fatiguing than the HS8. The LSX II LT’s coaxial driver keeps the tweeter centered in the midrange, but its small drivers are SPL-limited: bass compression kicks in around 88-92dB/1m per speaker.
Buy the KEF LSX II LT when sound quality outweighs the price for you, and the PreSonus Eris Studio 8 when the price outweighs sound quality instead.
