The Black Box is a Low Frequency Resonator Array that works in conjunction with the Subwoofers, Atmospheres and FEQ X4 to solve bass node issues.
sbayne, having the Rythmik F8's is very cool, as is using them as bases for the Tektons. May I make a suggestion? Go onto You Tube and watch all the Tech Talk Tuesday videos that Danny Richie of GR Research (Rythmik Brian Ding's collaborator) has made. Find the episodes in which Danny discusses the problems caused by employing multiple tweeters on the same baffle. With two Tekton's stacked, you are creating some serious phasing, lobing, and comb filtering issues. The huge distances between the various tweeters is unquestionably creating some out-of phase cancellation at certain frequencies.
But, if you like the resulting sound, that's in the end all that matters.
As before, I'm done with the forums for awhile. Many of the proclaimed "engineers" on these boards really seem ignorant. Just for the record, quantum physics is not new and using it to improve our equipment is not a pie in the sky idea. These articles explain Spintronics and how graphene can be used with other materials such as carbon, and thin layers of magnetic materials like cobalt and nickel, to produce predictable spin behavior in electrons. From one of the articles:
"Electronics is based on the manipulation of electrons and other charge carriers, but in addition to charge, electrons possess a property known as spin. When spin is manipulated with magnetic and electric fields, the result is a spin-polarized current that carries more information than is possible with charge alone."
Well, for about 6 months now, I've resisted going back to the forums and reading about PPT and Tekton. As I should have known, its the same old boring spittle of the objective people demanding scientific evidence of the subjective listening experience. It really does get old. I presented the same articles I've used in the past regarding Spintronics and how graphene interacts with other materials to affect electron spin. Seems like people either can't comprehend what is said in those articles, refuse to accept it or are too lazy to even read them. I'm sure I'll be attacked personally before the "discussion" ends. To be continued....

Just thought I'd share some interesting reading:
Spintronics
A conventional digital electronic system conveys a binary signal (think 1s and 0s) through pulses of electrons carried through a conductive wire. Spintronics can convey additional information via another characteristic of electrons, their spin direction (think up or down). Spin is related to magnetism. So spintronics uses magnetism to align electrons of a certain spin, or "inject" spin into a system.
If you've ever done the old science experiment of turning a nail into a magnet by repeatedly dragging a magnet along its length, then you've already dabbled in spintronics. The magnet transfers information to the nail. The trick is then transporting and manipulating that information, which requires devices and materials with finely tuned properties. Researchers are working toward the milestone of a spin transistor, a spintronics version of the electronic components found in practically all modern electronics. Such a device requires a semiconductor material in which a magnetic field can easily manipulate the direction of electrons' spin -- a property called spin-orbit coupling.
