Active Speakers Don't Sound Better


I just wanted to settle a debate that has often raged in A’gon about active vs. passive speakers with my own first hand experience. I’ve recently had the chance to complete a 3-way active center channel to match my 2-way passive speakers.

I can absolutely say that the active nature of the speaker did not make it sound better. Or worse. It has merged perfectly with my side speakers.

What I can say is that it was much easier to achieve all of the technical design parameters I had in mind and that the speakers have better off-axis dispersion as a result, so it is measurably slightly better than if I had done this as a passive center. Can I hear it? I don’t think so. I think it sounds the same.

From an absolute point of view, I could have probably achieved similar results with a passive speaker, but at the cost of many more crossover stages and components.  It was super easy to implement LR4 filters with the appropriate time delays, while if I had done this passively it would require not just the extra filter parts but all pass filters as well.  A major growth in part counts and crossover complexity I would never have attempted.  So it's not like the active crossover did any single thing I couldn't do passively, but putting it all together was so much easier using DSP that it made it worthwhile.

I can also state that as a builder it was such a positive experience that I may very well be done with making passive speakers from now on.

 

All the best,

They do at my house!

In my experience, when I horizontally bi-amped my speakers with an active analog crossover design by the same manufacturer (of the speakers) it brought my speakers two notches above the passive crossover in sound quality. There were lots of improvements with an active crossover, four that stood out the most were better dynamics and transient response in the bass, highs were cleaner and better delineated, the sound was more live sounding then recorded. All amplifiers and active crossovers are external of the speakers. In my opinion, amps inside speakers is not a good idea because the amps are subject to all the vibrations and air pressure and stray electromagnetic fields from the drivers inside the speaker cabinet. I guess I’m not a passive guy. LOL See here. 😎

A bit of history for the fun of it, the first powered and active speakers from JBL 1959-64 Hartfield and Paragon see here.
