As some may know, I’m an avid DIYer when it comes to speakers. I’ve built both passive and active and worked with pro sound speakers in theaters. I am ambivalent. That is, I have two strong opinions about each being a good choice.
Without getting too much into the alleged technical merits of each design, the thing that passive speakers give me is the ability to chose a very colorful amplifier. Consider my favorite amps of all time are CJ Premiere 12s. I don’t consider them neutral, but rather juicy, colorful liars. Heaven.
I just built a fully active, DSP driven center channel. What did I get? Excellent off-axis frequency response and massive dynamic range (comparable to ATC’s claimed figures) in a compact package along with objectively neutral frequency response which doesn’t mind being on a shelf while avoiding the need for yet another amplifier in my rack. Much as I love my Luxman integrated, I keep asking myself if I wouldn’t rather make 2 more active speakers and reduce my combined HT/stereo setup to 1 processor instead.
If you really want to pick your amp, go with passive. If you want to pick a speaker and not have to worry about your amp, go with active, but in no case should you pick speaker A over speaker B based on which of these types they are.
In the consumer world there are a lot of benefits to active speakers we may not care about. Dynamic range and power loss for instance. In the pro world we need every watt, and active crossovers deliver that. In the home world we are fine losing many DB’s of output due to massively overbought amps. 😀 That is, I can point to some technical benefits of active crossovers/speakers which are true, but perhaps irrelevant?
As a consumer, do you really care that building a DSP crossover is much easier (not easy!) than passive, since we aren't swapping parts in and out during the prototype phase? Not really. Does the digital time delay and off-axis frequency response matter to you? Most passive speakers do an excellent job with horizontal dispersion. The center I built though needed excellent vertical as well as horizontal dispersion, and that's a feature I could only really consider in active/DSP configuration. Point is, a lot of the technical differences vanish for most of us.
