Re: better solutions in our audio systems

In active speakers the amps are driving an inductive load, in a passive speaker the amp is driving a reactive load, which, according to Brad Meyer, increases the current demands on the amp to as much as several times that demanded by a simple resistor. In his article about active speakers Bob Stuart mentions a factor 3. Which would mean that the 400 Watt amp, as used in my speakers for the bass driver (8 Ohm, 98 dB), equals to a 1200 Watt outboard amp.

So if you want live-like reproduction you not only need live-like timbre but also live-like SPL. Hence BIG power amps for those who have inefficient speakers. So why do audiophiles stick to those technically obsolete solutions?
