I haven't heard this particular model, but I have seen Bob Zeigler's cab work, and he is a very compulsive and talented artist. If these are anything like other speakers he has made, they will give the owner the feeling of cheating the system. His work is that beautiful.
They could be the ticket for someone in the market for some very sharp looking mini-speakers.
