Not clear or God forbid green! Think about what a traditional passive crossover consists of , coils,inductors, capacitors etc etc the signal has to go through all of them, electronic crossover is better and a digital implementation allows you to use steeper slopes , use dSP to correct any driver anomalies , correct phase ,delay etc etc.
Active means one amplifier dedicated to one driver, how can that not be advantageous? Of course there is no oppurtunity to 'upgrade' amps, cables etc. Cosmik Major Contributor. The question is: if passive crossovers had never been invented, and active systems had always been around, would anyone now be pushing for passive crossovers? I am sure that CAD can design them to achieve arbitrarily complex responses - I have in the past written a program around SPICE to home in on a desired response, myself - but there must always be the issues of damping and other interactions with the drivers that change with temperature and power.
And also, without DSP-based active systems you cannot sensibly achieve linear phase and time alignment - although I know that everyone says this is utterly pointless.
As with the debate over time alignment and linear phase, I think that starting from ancient technology as the default position - and spending more on it than the undeniably more accurate active system - is perverse.
Wise words indeed! It is interesting that in 'pro' audio active loudspeakers are accepted without a second thought , the advantages are acknowledged and accepted , yet the traditional manufacturers, magazines have managed to persuade punters that 'traditional' is somehow best.
HiFi is truly a unique and bizarre pastime. I am certain from a technical standpoint ATC would prefer to only make active versions, but they are a business and have to offer what the market demands. I would prefer my speakers were active but only for convenience really, if there was a huge audible advantage between the two approaches we would know about it as there would be demonstrations at every hifi show to highlight this.
Personally I would love to compare a active G3 to my passive version in my own home. With the issues of room construction dimensions and build material and speaker placement in many cases this all becomes a rather moot point.
Unless you believe all amps sound the same there is merit in being able to chose your own. ATC make active and passive versions of the same loudspeaker so a comparison is perfectly possible. Solid state amps IME given the usual caveat of being properly designed do sound the same given that they are being used to drive loudspeakers ,which they are physically capable of driving, I'd not clipping.
All the more reason for a dedicated amp per driver. Thomas savage said:. Last edited: Jul 29, Cosmik said:. I have pondered on doing this, to demonstrate at hi-fi shows, but there are issues of course. The main one is that going active allows you to build a different speaker in the first place. Merely converting an existing passive speaker to 'active' would not demonstrate the true capabilities of the active approach. Umm, most actives I see are just a box with drivers in so I am curious to know what these 'different 'speakers you speak of are other than the relatively new beolab 90 I can't think of many.
In my opinion, passive crossovers are useful for small 2-way systems, or where you aren't looking for the ultimate in performance.
