I am now on my second pair of LSX II’s and this is not because of failure or unhappiness. It is because I am so impressed with the sound when paired with the KC62 and elevated on either the speaker stands so the desktop plinths. I mention this because before I had the stands/plinths I was not 100% convinced that I had made the right choice.
Now that they are on stands, integrated with the sub woofers, and positioned to suit the two rooms that they are in I am a very happy listener. Classic soul and funk, rock & roll, reggae and power pop they cope with it all with a depth and punch that makes an old man smile.
Very real finding👍🏼 Many pure stereo music listeners don’t believe such listening could also benefit from a subwoofer.
It’s simply because most speakers are not full range speakers and are simply not able to render LF properly or at all. So, you lose frequency range in the lower end. A properly setup subwoofer can compensate this lack very well
… and I’ll add… bass needs to be managed in the room differently to mid/top frequencies
Sub(s - preferably two or more) allow you to do that by positioning the bass source most effectively
For me, that’s actually more important than the raw frequency capability - you could have a stack of huge drivers with enormous power - and still experience weak/poor bass if you and they are not positioned correctly
To illustrate, I have 12x 10” drivers in my bass channels powered by three Lyngdorf amps (400w each) - sounds terrific, but I know there are some frequencies I can’t hear/feel eg Air’s Alone in Kyoto and Julian Cope’s Don’t Call Me Mark Chapman both have sub bass that you can’t hear but feel - in my current room I can’t get them to work without compromising other aspects of the sound
