Active speakers
Our hearing covers a very wide range. We can hear anything between 30 and 20.000 Hz (when young).
To cover the entire range is a very demanding task for a loudspeaker.
It needs to move a lot of air to reproduce the low bass so it must be big and becomes heavy.
It needs to be very fast to vibrate at 20.000 Hz so must be small and light at the same time too.
This is so demanding that the task is split.
The bass is handled by a woofer, the treble by a tweeter.
Feeding the treble to the bass probably results in some distortion, feeding the bass to the tweeter simple burns it.
We need a low pass filter and a high pass filter to see to it that the speakers only receive frequencies it can handle.
This is called a crossover.
Passive speakers
Conventional speakers have a build-in crossover.
As all the power of the amp runs through the crossover, only simple components like capacitors, resistors and inductors (coil) can be used.
This is called a passive speaker.
Allmost all speakers at the home are passive.
Active speakers
In the eighties the pro-world discovered that you can improve sound quality by removing the crossover from the power path.
As you can't do without a crossover; it is applied on the signal before it enters the power amp.
This allows the implementation of better and steeper filters because now active components can be used instead of passive components only.
It also allows for correction of differences in phase.
This is covered in more detail here.
The obvious consequence of an active speaker is that because you connect the power amp straight to the speaker, you need an amp per speaker.
Sounds expensive but today electronic components are cheap.
That beautifully machined aluminium box containing the electronics is probably the most expensive part of an amp.
Most of the time active speakers have the amps build-in. Indeed saves you the cost of the enclosure and keep signal path short.
Almost all studio monitors are active speakers.
Some models are simply speakers without a passive crossover inside.
They are supposed to by driven by an external Xover and amps.
I call them "active ready".
Powered speakers
Not all speakers with build in amplification are active.
A build in amp can be used to drive the speakers in the conventional way using passive crossovers. This is called a powered speaker.
A lot of speakers targeting the desktop are build this way.
This is a matter of space and cost saving.
Active crossover
Active crossover can be implemented using the traditional electronic components but it can also be done by using a processor.
This is covered in more detail here.
Active speakers are rare
Well, not really. If you look at the pro-world, a lot of studio monitors
are active.
But active systems targeting home audio are a bit hard to find.
I wonder what the differences between the pro-monitors and the domesticated versions really are, choice in veneer?
If I tell you there is an active system
- Digital input over the network
- AD converter for analogue input
- Equalization in DSP
- 4th-order Linkwitz-Riley crossover in DSP
- 4 DAC’s + 1 for the woofer
- 4 class D amplifiers
- Headphone amp
- 2 woofers + 2 tweeters
You don’t expect it to cost $300 don’t you.

Compensated Phase Response
The CPR system consists of several all pass filters who each act in a specific range of frequency in order to obtain a wide area of Compensated Phase Response. This then provides a constant group delay.
Adaptive Output Impedance system
The AOI system is constituted by a detection of the movement of the membrane and the moving coil, as well as by a counter reaction filtering. Therefore the damping rate is continuously ideally adjusted according to the frequency. The AOI circuitry is almost capable of reproducing a square wave and therefore increases accuracy by marring the transducer and the amplifier in to a perfect couple. A nice side effect of the AOI system is that the membranes of a PSI speaker do not produce parasite sounds when other speaker systems in the room are in use. When air pressure is produced by other sources than the PSI speakers the AOI will detect this and tighten the damping of its transducers in order not to produce parasite sounds not originating by the speaker system in use.
