Which comm. speaker mfgr. makes the best cabinet?

If you are considering cabinets that's are innert you would have to include Sony's top of the line. They are pyramid shaped and if my memory is correct Stereophile demonstrated little to no peaks in the cabinet throughout the frequency range. Now, I have never heard a pair, nor their super duper new variant but on this variable alone it is worth mentioning.

I wouldn't rule out Soliolquy..........

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.

Now that I think about it Merlin's are innovative with there cabinet design. Those 3 lines in the front and on the top are brass I believe and run all the way through the speaker(there is some reason for this but I don't remember at this time), it is also made of some composite(not mdf) material; a mold if my memory serves me correct. Striked me as being a little weird for a high end manufacturer to do something like this.

There is a whole new cabinet design on the market, www.zucable.com I have the druids and they are amazing. There is an opening on the bottom (not a port) and there is no filler in the speaker (batting). This is a new animal, check it out.
