Bass: Dynaudio Confidence C2 vs Contour S5.4


I am cross-shopping the above speakers as an upgrade from my current C1. I prefer moving to full range speakers rather than trying to integrate a sub. Looking at the stated frequency ranges for the two speakers is interesting:

The Confidence is listed at 28Hz–25kHz and has two 6.5" drivers.

The Contour S5.4 is rated at 30Hz–27kHz and has two 8" woofers plus a 6" midrange.

Based on driver assortment it would seem that the 5.4s should have more slam and extension. Am I to believe that the C2s actually go deeper than 5.4s? The local dealer does not have both models in stock for a side by side.

Power will be via the new Bryston 4B SST squared. Again, I'm wanting to upgrade because I'm a closet basshead. The C1 is awesome in everything from the midbass up, but I can't help but feel like I'm missing something.

Thanks

I guess another way of phrasing my question is: can the C2 really go down to its claimed 28Hz without significant rolloff? Any C2 owners able to corroborate the frequency ratings?

Thanks!
I've owned the C2's (28Hz) & now the C4's (27Hz). The difference in bass output is significantly more on the C4 than the 1Hz difference in the published specs. I think the 28Hz is somewhat deceiving, albeit not intentionally.
I've owned the Contour S5.4, C2 and C4. The bass on the C2 does go low but only if you feed them lots of power and turn the volume up past normal listening levels. At most listening levels I didn't think the C2 had enough bass. Save up for the C4
