Ironically, that’s a question. I sought to answer myself, but I’m not sure I ever truly answered.
When I had both the 3.7 and 2.7 at the same time, I found it they were very close in terms of the sense of bass depth. Although I could tell that 3.7 went a tiny bit lower, and had a slightly bigger sense of overall scale.
After I sold the 3.7 s, I was generally fine with the frequency range of the 2.7, but I finally did try and integrate a couple of subwoofers. I had two JL Audio 110E subs, a terrific CR1 crossover, and a Dspeaker Anti mode for room correction in the bass.
The difference was actually pretty subtle subjectively in terms of extending the bass and what it added to the sound. I would say, yeah, it added, perhaps a bit more scale and dimensionality. But I don’t really I didn’t like this slight change the characteristics that the subwoofers brought to the overall sound. Plus I found at least my room 2.7 sounded more punchy without the subwoofers. So I sold them.
Ultimately, if you upgrade to the 3.7s what I think you’ll get is a little more reach in the bottom, but not a lot. But also some greater scale to the sound in terms of imaging and sound staging, and slightly more refinement overall to the sound. The bass is a bit more linear, The mid range and highs a bit more suave and refined, and the 3.7 speakers disappear a little bit better.
I hope that’s helpful.
