I think maybe that the person actually played some actual bass notes.
I can barely hear any bass on my laptop speakers... I can hear the top of the swell.
Which, indicates to me that the bass part is actually a bass part.
That suits my personal preference, but it sort of defies the common approach of playing a bit higher up the scale so that the cheapy speakers play some bass.
I like my kick and bass to sound great on a system that actually plays back the lows with authority. I find that when I play the low E and love it on my real systems, that sometimes it just disappears on cheap systems. That's not ideal, but it sure sounds good on a nice system.
A lot of "bass" parts these days are episodes of hyped lower mid range because it translates well on modest playback systems.
I'm imagining you are enjoying the bass in that song on a nicer system for playback... or perhaps headphones... and I think I would too.
Perhaps you are simply responding to the novelty of hearing a true bass part?
If that's the case, I'd say any simple setup with enough power and a speaker that can actually play bass tones will do it. It's all in the player... but a SVT with a JBL wouldn't hurt.
