Well, if the amp really
is FCC certified (I'm assuming it's some kind of a switching amp) then there must
be an appropriate FCC approved boilerplate comment placed in the manual. Does yours have that?
As far as UL, I'm not up on the requirements for electrical components as part of a completed product like a subwoofer (which would be electro-mechanical). I know UL does testing of completed electrical products. Not sure about components, however.
Me either. With all due respect to AV123 customers, I personally consider AV123 not adverse to taking shortcuts and as a guide (not proof mind you) I'd consider examining other subwoofers from places like Paradigm as well as their manuals.
Moreover, who is required to get the certification? The company using the electrical component as part of a completed product? Or the company who manufactured the component? A step further, who's required to submit it for certification?
Well, to be flippant I could say contact AV123's engineering and legal department but we both know that doesn't exist. But just to address one aspect of your comment, if you buy the amp from an outside contractor and its intent is to be used in domestic applications, then I'd say the manufacturer of the amp is required to do so. Now, that doesn't mean that the manufacturer doesn't enter into negotiations with the buyer if the buyer is the exclusive user of these amps as to how that's paid for.
Now, you know I'm kind of a suspicious guy, graphicguy. Wondering what's hiding under the stone if you will. So, let me toss something out for you. As I understand it, the MFW's were made with a domestically sourced subwoofer driver. I also understand that it's a custom job but that the driver itself has no identifying markings on it. How do you know that future drivers will also come from that same manufacturer and won't be sourced from another company. Maybe one from India or China? Maybe one that's a perfect match. Maybe one that's not so perfect a match.
Anyways, aside from the amp issues as pertains to the MFW, there are numerous other issues that AV123 must take in order to move forward successfully.
