this to to compare the Smaller Advent Loudspeaker to the EPI 100, correct? The baby advents are different speakers.

Baby II measured response here:I just picked up a set of Baby Advent IIs tonight, close to mint, intact surrounds, and I can at least compare them to my mutated EPI 100s.
Like the highs of the 100s much more and the midrange hole noted above is something I would typically create with an EQ anyway, the Baby IIs definitely need it for my tastes. The 100 gets the nod in bass as well, smooth, clean and tight. The Baby IIs are OK, but the smaller enclosure and woofer just can't compete with larger driver and enclosure.
The Baby Advent is not the Smaller Advent. They are completly different systems. The baby is much smaller and does not have the low end of the smaller. Different much cheaper woofer, tweeter and cabinet. Completely different engineering.
I own EPI 100's and have owned smaller Advents. I would say the EPI's are far superior. The Large Advents might start to compete, but the smaller ones fall way short IMHO.
