As a very happy Daedalus owner (the Ulysses model), I'll second the comment by Dodgealum. I'll add that their combination of high efficiency, high power handling capability, and an unusually flat impedance curve provides exceptional versatility with respect to amplifier selection. And I wouldn't be concerned about the fact that the Ulysses and some of the other large Daedalus models are rated at 6 ohms, rather than the 8 ohm rating indicated in your criteria. The lack of significant variation of their impedance over the frequency range, as well as the lack of significantly capacitive impedance phase angles, result in their 6 ohms being very unchallenging.
The one uncertainty I have relative to your stated criteria, though, relates to your specification of "full range," and what that may mean. The Ulysses and other similarly sized Daedalus models have bass extension rated to 28 Hz, while I note that the two speakers you referred to are rated to 23 and 20 Hz respectively. But in the absence of evidence to the contrary I would apply many grains of salt to those and most other specs for speaker bass extension. Partly because such specs rarely indicate the volume level, distortion level, or anticipated room gain that they are based on (although the Crescendo's specs at least indicate a tolerance, that being +/- 3 db). And partly because I would not expect most speakers having a pair of 8 or 9 inch woofers to provide bass extension below the mid to upper 20's, at least at realistic volumes and with reasonably low distortion. Regarding the Ulysses, though, I have made measurements in my room that are very consistent with the specified 28 Hz figure, at reasonably high volumes.
Good luck in your search. Regards,
