Haha tough question...the room is probably about 18 by 18 with one corner being taken out by the kitchen area.  The way the doors are setup the speakers will be projecting from a short 9 foot created wall created by the doorway and down the full length of 18 feet.  One speaker would be positioned next to a long wall and the other would be next to an open space.  I can use my microsoft paint skills to draw the layout if you think it would help.  The easiest way to describe it would be a 9 x 18 foot rectangle that is open on one side.

Truthfully I think that the single driver is probably the best option given the amplifier.  The only thing that concerned me was the frequency response of these drivers typically being all over the place or heavily favored towards the mids.  This is why I was looking at something like the Tekton speakers.  That being said, I think they would need more power than 3 watts to really take advantage of the crossover design.  It's not necessarily about volume, because I listen at quite low levels.  Its more that muddy/veiled sensation that I get when I heard orthos out of a portable amp.  For some reason I just felt like they were capable of so much more even though the volume was quite loud.  I don't want my speakers to sound like that as well.

Understood. You may want to contact the guys at GIK Acoustics for placement (and possible treatment) advice, that kind of challenging setup is well beyond my expertise. Everything I've been hearing from people who have the new version of the Super 3 has been very positive. I'm planning to try the Super 3E monitor version myself on my desk. I've gone through a boat load of two-ways and found them all to be disappointing in a near-field desktop environment, including active studio monitors.

Probably the ideal desktop speaker would be a flat membrane coaxial arrangement like Vienna's driver in the Klimt series that could act as a true point source, without the inherent wave guide effect of the normal cone shape of something like KEF's Uni-Q. I don't know of anybody that makes something like that for a reasonable price, though.

This is a good read on high efficiency speakers- http://www.troelsgravesen.dk/HES.htm

Basically it says that you need big cabinets to get any type of bass response.

That is a great link for information on single driver high efficiency speakers. I am familiar with the notion of high volume cabinets for bass response. Space is an issue for me though and I am not really bothered by a lack of bass. It would be easier for me to implement a sub if i needed to rather than deal with 200 litre speaker cabinets. With something as large as he recommends I fear that the bass response will be delayed on all but the best designed speakers.

Looks like I will end up going with the super 3s. They also have a Canadian dealer which is nice.  While looking up the omega's i found the hoyt-bedford line. What is the difference between these and the omega?  Is it just the modular design?

You could go vintage like I'm doing. I currently have 1960s Altec compression drivers and a custom 15" woofer designed to play nicely up to 500hz or so. I did add a B&W tweeter to add to the highs but since the tweeter isn't as sensitive as the rest, the sound needs some bass/treble tweaking to sound balanced.

You can get at least into the mid 50Hz region with the Super 3, which may be enough. If not, I would definitely recommend checking out one of Anthony Gallo's subwoofers. They are pretty fantastic in terms of performance/price.

The Hoyt-Bedford models are similar to Omega's larger Super 6, but use a much less expensive driver than the Super 6 Alnico.

Mid 50hz is fine for what I want.  If it really bugs me I will get a sub.

The next question is whether to go for the 3s or the XRS.  I read Louis say on another forum that the 3s will have more bass extension, but the imaging and soundstage of the XRS are the best in the lineup.  I will probably just email him and see what he thinks for my situation.

For right now I am going to stick with getting something new from a manufacturer.  The vintage idea and DIY stuff that donunus and RudeWolf posted looks neat.  I just don't want to deal with the potential hassle of either of those options at this stage when I can get something new that fits my criteria (and is very convenient).  That being said I would love to hear more about DIY speakers.  I spent a lot of time looking at DIY full range speakers before I decided that I do not have the ability to adequately build and tune them.  Some of the rear loaded horn designs that I saw on the Frugelhorn site look really interesting.  I always wondered if these could noticeably improve the full range fostex and lowther drivers performance.

Right now I am thinking of something like the Tekton M-Lore or Parker 95, but obviously any other suggestions are welcome! 

A friend of mine has the Parker 95 powered from a Decware Taboo and I thought it was really nice. The sweet spot is wider than it is tall. Actually, moving off axis vertically is quite dramatic. It wants a sub to back it up too, as it's a little light on the bottom end.

Not sure if I like stuffing one hole or both holes. Tending toward one hole since both holes seems kinda ghey ~Purrin
