its amazing to me that people would push a $100 amp outside of its operating design
Hey - the $100 amp (Fosi BT30D pro) works great in our application ! All we had to do was ventilate it. But I'm not supposed to use it? Maybe I can clarify.
There is no money in our projects nor any need to get into professional equipment. Our events are 15-25 friends on a patio for a weekly non drinking dance. No money is involved. Few have much. We previously put out computer speakers which were just not loud enough, so I organized a small system for a bit over $300 US. Brought bookshelf speakers from US to Mexico in my suitcase to keep cost down. Built a heavy sealed sub box using a $40 10" car audio driver that matches well for lower wattage amps and adds some bottom end.
Blasphemy, right?!
Everyone appreciates how good it sounds, big difference. Glass half full. Perhaps you would hate it and walk away.
Loing ago I was in commercial audio and video production as a professional. I did sound recording on film sets a few times but mostly produced tiny projects. Dabbled in live sound as well, organizing and operating a budget sound system (think Peavey Shure, etc.) for a local rock band for a few years making sound listenable and danceable in clubs to big parties. I made it work with just enough. I also went out a few times to do live sound with a friend who worked for a fine little company called Meyer Sound out of San Francisco. They had the gear.
Doesn't mean much but I'm no fool. I am also not an audiophile but like it to sound pretty good and can't tolerate the distortion that many do.
Wrong profile for this site? I was attracted by the science part I admit. I like an engineering approach to things. And the best reviews for the gear I was buying are here.
So to sum up this little line of discussion, Talisman insists that Fosi should not take any cooling measures of any kind in their products to assure function and durability because no user will ever be any different than you, and... well, if some users
are different then that use is not legitimate. Tonyzdk agrees that our use is not legitimate and by extension users like us should not have any consideration in product design. Indoor users only?
Clearly, for some audiophiles, even passive cooling of a class D amp is a bad idea that should be avoided. Go figure!
