Single driver point source speakers vs. the world?

"for those with point source design experience is does the lack of a crossover in designs equate to these types of results in other point source or single driver designs?"

As pointed out, lack of crossover and point source are two different things both of which can help produce better results. That aside, I would say the answer to your question is a resounding yes.

I'd really like to put a pair of C&C Abbeys in my living room some day. I love the look and can imagine how they sound.

The high efficiency & the absence of X-over is the only common thing among the 8" full range drivers.
BUT :
There is a world of difference between (ie): a Lowther PM7A and a WE 755 or a Fostex Fe206E and a Feastrex Naturflux.
Also you can consider some coaxials (ie): an Altec 604 and a PHY-HP KM 30. (from different planets also)
While the coaxials are using a minimalist X-over, there are not less atractive than the single F-R drivers, most (if not all) of them are asking for an added tweeter, so in the end you are forced to use a minimal X-over also. (not to mention an active sub.)
If you prefer the single F-R driver instead of the 3 way compression drivers, I'm sure its not because of the X-over... that is not the limiting factor of these speakers.
So, maybe the attractive factor is not the absence of X-over. I suspect is the time coherency of their nature.
When you keeping low the expectations, everything are going fine. But the day that you start thinking for the upper limits... the experience will come to you only with hard work and after many failing projects. The point is that the success & satisfaction probably would never come.
It is the nature of the beast. We love it but we are not accept it's limitations and we were going for tweeks & mods until the end of the world.
Oh yes Sir.

cwlondon, my computer speakers are Merrill Zigmahornets. 4" single driver speakers with surprising bass for the design. The lack of low bass makes them office friendly by not bugging my co-workers. The lack of exaggerated highs mean that they are non fatiguing. I used them 4-8 hours a day every day!

Single drivers are great. In an ideal world though, I think my Acoustat 2+2's were amazing. I just need a 20 x 30 living room with 12 foot ceilings, not kids, no dog and a blindly devoted wife who can overlook the entire room.

I was interested to see the speakers in a tall "matchstick" shaped enclosure in a 6 Moons review, which raved about them.

Then I found other posters saying that 6 Moons reviewers must get paid by the paragraph, because although OK for the money, nothing really "high end" about the sound.

I am assuming you do not have the matchstick cabinets on your desk top?

What cabinets are optimal for the single driver point source?

Weakness...

High THD, high coloration, limited bandwidth, limited SPL, limited musical repertoire..

Does have a good mix with SET's and being full range favors the middle bandwidth over the other. Agree about the chip amp a few friends with Cain & Cain's uses them 2.

One would have to have pretty poor panel speakers IMO for a small single driver speaker being driven with 8 watts to be an improvement.....
