Here's the latest on the new line source speakers Bob Carver & James Sauter have been working on. Will be marketed under Bob Carver LLC:
This speaker will produce 121 dB SPL without distortion. Power handling is 2,000 watts rms without distortion. Sensitivity is 96 dB SPL @ 2.83 volts rms. It uses four vacuum tubes, four for the active crossover. There are three modes. Active crossover mode which requires two amplifiers for each speaker. Passive crossover mode which requires one amplifier for each speaker. Either mode may be used with or without a separate sub-woofer, yielding the third mode. It does not need a sub-woofer because it has so many drivers that the total air displacement is vast. All it needs is low frequency equalization for the woofers to make the system flat. That job is performed in the crossover box that comes with the speakers. The crossover box has the following controls: Low frequency Q, upper midrange level, high frequency level, and two switches used to set the system up mode-wise. It is very easy to use.
The imaging and tonal characteristics are similar to my Cinema Ribbons, the differences being that these speakers possess a majesty, a bigness, and a sound with sonic and emotional envelopment that normal speakers cannot. They are the best speakers I ever designed. Les Williams said they may well be the best speakers EVER! All based on the work so far.

These are the prototypes. Minor adjustments left, but they are 75% done--
The last pic above is the builder, James Sauter (Toy Maker on carveraudio) & The BobFather.
The stands are temporary; they will actually have feet something like this:
This is a shot in a mock-up plywood. Final will be extruded aluminum.
This is funny: a shot of the passive crossover components that were swapped out during test/voicing:
