It is important to understand that a consumer integrating a passive speaker system into a home theater or home entertainment solution might be assembling the various components by piecemeal. In this manner, the consumer is left with the task of matching an amplifier for the particular passive speakers selected, or vice versa. This is both an advantage and a disadvantage to a passive speaker scenario. One has the freedom to upgrade the amplifier, or swap it out at any time, where in an active speaker scenario the amps are part of the speaker package. What you hear is what you get, generally speaking. But, the manufacturers of amplifiers don’t know what speaker system will be matched with their product, which is why amplifiers are “over-built” to accommodate a wide range of speakers, a move that results in more expensive and more power consuming amps. 

Powered Speakers
Here is where things can get muddied. A powered speaker is technically one that has its own amplifier built into the speaker, and therefore plugs into a nearby outlet. However, a powered speaker is not necessarily an active one, as the crossover components within a powered speaker can be passive. Powered speaker systems have the advantage of being a bit more streamlined, compact, and portable—most speaker systems designed for desktop home computers (such as Xhifi), laptops, single-room application, wireless multi-room application (like Sonos), and easy all-in-one iPod-docking-and-speaker-solution (the iFi) fall into the “powered” speaker category. But unsuspecting consumers can get fooled into thinking that a powered speaker is better than a passive speaker. In truth, a powered speaker can still have the “amp-passive crossover-driver” chain characteristic of any passive speaker scenario. 

“Powered speakers can cut costs, and reduce clutter,” says Logan Pabor, Distribution Manager at Audioengine, a powered speaker manufacturer. The built-in amplifier feature of a powered speaker solution enables wireless speaker scenarios, and eliminates the needs for additional, expensive components. “Set-up is much easier, and there are no external components,” adds Logan. 

Conclusion
It would be inviting widespread criticism from all sides to claim one technology as superior over another in this debate. Certainly there are pros and cons to each system, and ways of perfecting (as nearly as possible) one system to “match” the performance of another. As with most such debates, the comments from those with experience are often as informative as the facts themselves.

I have an older Mac G4 that I now run through a very cheap home theater system in my basement.  Better than the computer’s sound output for sure. Is the sound output relative to the computer or relative to the powered speaker’s capabilities.  What’s available for purchase?

I wasn’t aware of the many ripples and depth to this story until I   surfed here through Google! Great job.

I have a small band and would like advice on the best speaker system or audio system to use. Usually i have 2 singers, 3 musicians tops. Any advice?

Nice balance in the article.  Not.  Love how all the “experts” are from companies that specialize in powered speakers.  Why bother to write something this one-sided?

This article is well written and does an excellent job at identifying the important distinction between “active” and “powered” loudspeakers which by design has misled consumers for some time. The drawbacks inherent to passive crossovers are many and Bart LoPiccolo from Genelec did a good job at explaining some of the key issues from the company that is most credited with the proliferation of active speaker technology. What I believe is worth mentioning is, just because you may own or choose to purchase a receiver with an amplifier section, this does not negate the advantage of active loudspeakers. Many feel that this is a waste of the money spent on the built-in amp portion. Not so, even if you utilize on the preamp section of a decent receiver by connecting preamp line out to your active speakers you still have gotten your money’s worth. Receivers from companies like Denon, Integra and the like have an economy of scale that could be considered to make the amplifier section free. Dedicated preamp/processors begin at price points well above the pedestrian $1200 receiver. Preamp/Processors are costly in large part due to the fact that engineering costs must be distributed across far fewer sales when compared to a receiver that will be sold at countless mass merchandisers. The receiver is a very economical way to put a full-featured preamp in front of a nice pair of Genelecs, Dyns or whatever you may choose and the active technology will have first-time listeners breaking out their CD collection for a fresh listen guaranteed.
