As an aside, I understand most subwoofers employ Class-D amplifiers. My first subwoofer was not. It had a honking big heatsink which would get hot. My current one is MUCH more powerful, yet doesn't have a heatsink. I was concerned about this, but it doesn't even get warm during operation. This implies a lot less power wasted as heat. -- Mark Lanctot "It's like, you know, a New Age religion, but with better treble response." - Jon Heal ------------------------------------------------------------------------ Mark Lanctot's Profile: http://forums.slimdevices.com/member.php?userid=2071 View this thread: http://forums.slimdevices.com/showthread.php?t=31789 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
