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.
After looking at my order again its actually called magnetic sheeting. I ended-up calling them directly and asked them to cut the sheet into 8x11 mats which they agreed to do. When I got the order it wasn't cut but they gave pretty much an entire roll of the stuff which I believe was 30'. Anyway, this is what I used.
Hi Tom - thanks for the feedback. Good to read I'm not crazy thinking these magnetic mats help the sound quality. I've always thought keeping magnetic fields away from our stereos was the way to go. Maybe its actually keeping "stray" magnetic fields away but focused strong magnetic fields are beneficial.
As to the graphene oxide, I simply used a paint brush to apply it to the mats. I put the mats together while they were still damp. I didn't wait for it to fully dry. I continue to read about graphene oxide and I'm not totally sure its positive effects are all about conductivity. It seems to create a coating that can be used for many purposes including improving batteries, optics and electronics. I'm not going to try to explain why (because I don't understand it). Do a simple Google search. Its fascinating reading.
Thanks Bill. Here is what I've been using:
You can buy different quantities from this seller. It says for "R&D only", "keep out of the reach of children", etc on the label. So, I wouldn't drink it :-)
Also, please let me say I have no idea if this will work in every system. Its just a relatively low cost (ongoing) experiment.
Bill - making the grounding box was easy. I ordered everything off Ebay one night when I decided to build one. The wood box came from there as well. I just checked and it doesn't appear the guy is active on EBay anymore, unfortunately. I just drilled the holes in the back of the box and added the binding posts. I used 10lbs of tourmaline and bought a roll of copper . In all, it cost me about $150. I think it was worth it. If nothing else it was a fun project.
The whole thing with the E-mat pissed me off. Really don't understand giving a product away to people who have no idea how it works and then squelching any discussion in that regard. I'm sure its a good product so let it stand-on its own and give us an idea of what's going on - I'm sure its much more than just a magnetic mat! Anyway, I'll report back in a few days.
Here are my thoughts on reviewers. I recently posted this in response to a magnetic mat that is being sold on Audiogon that was sent to a number of people free of charge. I'm going to copy it here so I can easily get to it for future use:
oregonpapa (Frank) - Thanks for the cordial response. I don’t think receiving a product for free obligates the receiver to post a favorable review but if the person wants to establish a relationship with the manufacturer and keep the freebies coming they would naturally be inclined to give a very positive review. I would hope a person wouldn’t be dishonest just to get free product but full disclosure allows a reader to make their own judgments.
We see this all the time with "professional" reviewers. They review the same companies over and over consistently spewing-out positive reviews. Toss-in the "reviewers discount" they usually get, the free meals at shows, the in-home delivery/setup/consultation and you’ve got to wonder if the relationship is a little too cozy.
A big reason I like reading "non-professional" reviews is because you assume the person actually bought the product and is not being "paid" in anyway for their time or effort to write the review. This is especially true when a money back guarantee is involved - they have decided it truly was worth investing their own money and didn’t return it.
As to my positive comments on products, I can assure you I’ve paid for all of them except for the Burson Audio cables I reviewed which I now agree Audiocircle correctly nixed.
