How can I make my own acoustic materials?

This is getting into another subject, Sean...those guys are using that 'mumbo jumbo'--which they headline as a 'technical discussion' to sell a $649.00 piece of gear!

For that kind of money I can get the tonearm fluid damper for my Technics 1200 TT ($149), an Ortofon low output MC super 15 MK II ($225), a pair of Tekna Sonic C-10 fins for my JMlab speakers ($99) and still have money left for albums!

Crazy, isn't it?

I agree that some "tweaks" are outrageously priced. Keep in mind that even though you might be able to go out and pick up all of that stuff mentioned for about the same price, you STILL might not be hearing what your system (especially your cables ) is capable of doing. Believe it or not, it is the "truth".

For the record, one can make a VERY heavy duty "cable burner" for well under $100 if one was "handy". It might not be as pretty as the fancy mass produced ones, but it WOULD work. Sean

I've just got my blueprints for the corner bass traps. Very well designed. I talked with Steve Deckert this morning about the particulars of my apartment setup. He was very helpful about helping me live peacefully with my neighbors...I've already recommended him with two of my audio salesmen. Definitely worth doing business with.
