Stainless Steel Audio Step Up

Maybe he's talking about an audio rack made of stainless steel?

Maybe he is talking about solid state! i.e., SS...elsewhere used as an abbreviation for stainless steel.

hi. im sorry yes im talking about stereos, speakers or subwoofers made of stainless steel. i came across with this cosmos soundwave theater the website and design looks promising but not sure how is the quality. thanks 

Well its basically made for the outdoors so I doubt it sounds very good. I am sure there are scientific and acoustical reasons why stainless steel is a poor material for speaker cabinets but I will defer to others with more knowledge.
