Definitely better than most sound bars out there if you have a smaller space. Heard this (or maybe a last-gen model) at Audio Advice Live last year and was super impressed!
Two reallly good speakers! We haven't tried them side by side but the L42ms definitely will have a wider soundstage and sound closer to a true stereo system. The Authentics can definitely get loud! But to us, is aimed for more casual listening.
I’ve had the 75ms for about 18 months, it’s not a sound bar this thing is big and hefty, sound is crisp and powerful no distortions I wish experience with connectivity apps was smother but great sounding speaker overall.
