I occasionnally make speaker cabinets for a high end speaker manufacturer in Montréal and done so for two others now out fo business. So when I needed a pair for my system, I let myself go . Here is a picture and more on my page.
The speakers are bi-amped 300w. I had the guy set the drivers and electronics in a typical size calculated square box and set the box into a curved face that I think helps in diffusion. This face is decorated with the marquetry of a stylised spanish guitar. The funny thing about it is that
nobody ever notices that the guitar has two sound holes.
Then I hung a micro system underneath one of the speakers that accomodates an iPod, mp3 CDs and SD cards. That system graces the dining room for excellent
soirées.
