Who makes these? what is the value on them?

I inherited some slightly older equipment. It has been sitting in my basement unused for 3 years, I am trying to sell it, but not sure the best route. I went on to the bluebook part of this site and got some values, but can't find my speakers.

They are made by Soundwave, and are called Grand Soliloquy (sp? at work right now). Large HEAVY speakers. Triangle shaped with two 6" and a tweeter on both sides of speakers. Shape is triangular. like this

The speakers are on the front sides. Almost bipol/dipol in design. I hooked it all up and they sound BEUTIFULL, unfortunately I don't use them that much and I want to use the money to get some higher end camera equipment.

Here is the other equipment.
Classe cp-50 (D/A converter)
2 B+K Components Reference 4420 2 channel amps
Theta Data Basic Cd transport
Theta DsPro Basic III digital signal processor.
And some rather large speaker cables that

where do you think the best place to sell this equipment?
