Apogees are not known to do well with subs. It is a mismatch between the fast ribbon and the slower box. Having owned Apogees before, you probably know that.
The Slant 6 is Apogees smallest floor speaker. I have heard it in much smaller enclosures, and with a precious tube amp, the realism is breathtaking.
For your size room, I would look for the Slant 8. or a Centaur. They will fill the room better. You must be very careful the speaker is in good working condition.

As for the Eto, it's a nice box.
