You are correct - I didn't cross-check my rusty memory. The CS3.5 bass in its enclosure is 'critically damped' Q.5 for no bass hump, which some critics consider 'dry' or over-damped.
Also my apologies for my final statement of 'excellent in every way'. I meant that the bass configuration was optimized for performance in the phase, time and frequency domains. In particular the EQ'd sealed bass keeps the fundamentals in time with the upper harmonics, whereas reflex bass places the (reflex-supported) fundamentals a full cycle behind the rest of the signal. Lots of controversy around whether such bass coherence can be heard or matters. I'm among those who say it does 'to me'.
