I love my Sonus Faber Extremas. They are a sealed unit for accuracy but have a radiator in the back to help with cabinet pressure.
They are slanted back a bit to help with the perceived phase distortion (timing errors between drivers) between the two drivers because of the different lengths in soundwaves of different frequencies. The two drivers are small and close together which also helps with phase distortion.
They are made out of wallnut on the outside which not only looks great but they claim it has also has an effect on sound quality.
I have also been told, but I have never seen, that the inside is shaped in a way to help break up or articulate certain frequencies.
And lastly the edges are smooth and rounded which help with reflection of the sound waves.
I read a book on speaker design and layed out all the options I would want in my custom speaker. The funny part was when I was done I noticed I had essentially designed the speaker I already own.
