Actually WATTS are machined and not cut with normal wood cutting equipment. They are VERY damped cabinets, the best I have ever had or heard. They are VERY HEAVY.

I have driven the WATT's with Dyna MK 4 tube power amps, and the original Electrocompaniet power amp. I do use more power today, because my best amp designs are more powerful than my cheaper (more compromised) designs, and I get the amps for free.

The most difficult fit that I have ever had in speaker design was with a horn mid-tweeter, and a direct radiator woofer. This was because of the strange group delay characteristics of the horn near its low frequency cut-off. It is much easier to put two direct radiators together, or even two horns together. John Meyer and I made a virtually 'perfect' transition with a 'transient perfect' electronic crossover and 3 horns, two of which were custom made, the midrange horn using a 2'' throat rather than a 1'' throat in order to reduce horn throat distortion.

My stereo enclosures too.

I had this stupid idea to glue a 1mm lead foil between two of medium and wood, and i injury myself each time i have to ask for help to move them.
I had no virgins around at this time to handcraft them, so i was obliged to assemble the panels by myself. That, and the lead toxicity explain why i'm so tired since this time ?
Tired and retired...

Of course, you did not see, and did not hear my concrete speakers... You live on the other side of the ocean!

The WATT's are lead lined as well.
I'm pretty sure that I heard the JBL speakers that you referred to, Morinix at a CES a couple of years ago. Pretty darn good!

They were my faves of all of Greg Timbers' designs. Wish I could afford a pair - even too rich with an employee discount for me.
