The speaker in the lower right hand corner is the much talked about M8aMKIV.
Run out and buy several dozen copies of the magazine to boost sales and Jon's ego :T :T :T
Seriously though, the article is a treatise on proper loudspeaker design. Should be required reading for the DIY crowd or anyone that want's an understanding of the who/what/where/why/how of loudspeaker design.
Note that the article is in 3 parts the Sept issue has part 1
