How large is your room and how large a cabinet can you tolerate??.
-3dB point, cabinet volume and efficiency are ALL tied together but the only free lunch in audio exists IF your room will allow it.

Hi Tom!
The actual room they'll be put in is 15.5' x 12.5' with a ceiling the slopes from 8' to 10'. That said there's only a 4'H x 5'W wall that separates the audio room from the kitchen and then an 8'H x 3'W wall that separates the kitchen from the dining room on the other end of the kitchen. So unless I'm mistaken --- and please correct me if I am --- I believe they speakers will see a 40'L x 12'5'D with the sloped 8' to 10' ceiling.

Hi Tom
Unfortunately your room doesn't qualify for the free lunch ( good room gain).
I would have to agree with a bunch below, your best option is probably a self powered sub with an electronic crossover / processor.
You can build a high sensitivity subwoofer and use a passive crossover but that is more of a job than it sounds like and will be much larger than the alternative.
Subwoofers are the simplest loudspeakers to build, if you have had the inclination to build something, do this or maybe build a kit.
I would suggest also looking at a loudspeaker controller as used in pro-sound, these offer a wide variety of crossover slopes and frequencies and other such things which make it much easier to get a happy alignment.
If you went this route, build two,put one behind each of your speakers.
To get seamless results, you need to be able to measure the response at the transition area and if you can, set up one speaker and sub outdoors and get the time, crossover and level parts right before fine tuning indoors.
Tom I just sent you an email. After you read it I think you'll understand why I didn't post it publically. Please let me know what you think.
