With active subwoofers demanding typical power levels up to 500W, building the amplifiers to meet the requirement is not without difficulty. Consider using a 50% efficient Class AB amplifier, and it’s ...

In audio applications there is a trend towards Class D audio amplifiers as replacements for traditional Class AB electronics. The main driving forces are improved efficiency and space savings.

Class D amps from $130 to $50,000—pulling more ears into hi-fi without demanding you sell a kidney. Solid tech, serious power, and none of the usual overpriced fluff. Finally, affordable doesn’t sound ...

Technology has democratized the music industry in many obvious ways – notice how every band, regardless of stature, has a MySpace page? But one of technology's more subtle effects has been to make our ...

Class D amps are simple – just take an input, and use that to modulate a square wave with PWM. Send this PWM signal to a MOSFET or something, and you have the simplest class D amp in existence.

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

CX-Series Amplifiers are the perfect combination of big power, bigger flexibility and true reliability! A variable 12dB crossover, KickEQ 6dB variable bass boost and a 24dB subsonic filter on mono ...

So I've got a bunch of car audio gear and I plan on going to be moving to Poland in a little while. Guess what? The car audio stuff isn't going to be useful to me anymore. So on the block ...
