Harman's home theater system is more than a little different.  It comes with the THX Ultra2 certified SDP-40HD surround processor, a pair of No. 535H multichannel amplifiers, two S820 stereo/mono amplifiers and the SDEC4500 digital equalizer/crossover.  

It comes with some pretty impressive hardware in the speaker department too.  You'll get three SAM1HF high-frequency horn modules, three SAM1LF low-frequency horn modules and four S4Ai MultiPolar in-wall surrounds.  You'll also get a pair of S1S-EX passive subwoofers, each boasting an 18 inch cone.

The system consists of products from both JBL Synthesis and Mark Levinson and runs $88,100.
