I have a Phase Technology 5T - what are they worth

I have the two speakers Phase Tech 5T, Octave Series Power 12 and the two smaller speakers you hang on the wall - this is a surround sound but the center speaker does not work. So 5 speakers what are these worth - excellent condition, haven't been used for six years.

I would appreciate any help.

Thank you,
I'm sorry but a simple online search indicates the Phase Tech 5 T is worth the cost of shipping. I would kindly hand those on to the next generation. The towers in good condition sell for $75.
