Why HiFi manufacturers don't make active crossovers anymore?
The thing most amateurs don't get about crossover design is that active or passive, it's more complicated than you think.why would it be complicated to make an active crossover work? All you would do is set the crossover slope and point and then adjust the response using EQ to suit your ears. Passive is much harder to do because theres no way to adjust the slope or point quickly. Its false that active and passive are comparable in difficulty of use. |
Interesting guys, thanks for the thoughts, will check it out the article that you shared.. Let me know what do you guys think about the Accuphase option that I posted above? Take a look at the brochure, and their option of use the PX-600 amp with the analog active crossover with 3 way speakers (the one with horns) I was thinking that example, would be a very straight forward and easy to configure, If compared for example: to build the exactly loudspeakers showed on the picture with passive crossovers... What you guys think would be more easy to configure? To build the passive cross over for a loudspeaker like that, or to cross over the drivers frequencies using the F-25 and amplify with the multi channel PX-600? http://www.accuphase.com/cat/f-25en.pdf I'm planning to build the loudspeakers with the same configuration of the one showed on the brochure of the PX-600, a 3 way, composed of 12" Woofer, Radial Horn, Super Horn Tweeter. I have the passive cross over plan, but thinking about the route of to use the PX-600 and F-25. What you guys thins about the pros and cons of the 2 routes? I have no experience in build a cross over, so I was thinking that the route of PX-600 and F-25, will me more easy, no? Thank sirs. |
but there are usually some trade offs, like 3x more amplifier channels, and a lot more parts that go between the singal and the driver. Audiophiles are generally happy to spend quite a lot of money on their equipment. Why would you be reluctant to spend a bit of money on another amp to obtain the benefits of going active, when youre happy to spend thousands on other things like cables and accessories which bring little or no benefits? There are less not more parts between the amp and driver with active. Less expensive capacitors and inductors. |
I’m seriously considering this, instead of build the passive cross over for my speaker project... http://www.accuphase.com/cat/px-600e.pdf http://www.accuphase.com/historys/pdf/cx-260e.pdf http://www.accuphase.com/cat/f-25en.pdf This multi channel amp and active crossover, would like to know more about if this example can be a more easy solution to divide the frequencies for the speaker’s drivers, instead of build the passive crossover for the woofer, radial horn, and super horn tweeter, as is suggested on the Fostex speaker’s plan. https://www.fostexinternational.com/docs/speaker_components/pdf/recom_enclose/w300aII_encl.pdf More, easy, straight forward configuration, but more expensive for sure... well this amp, preamp and active crossover from Accuphase I found some to sell occasionally on the web, sometimes the preamp and the active crossover appears at a more reasonable price in Japan I think.. Anyway, what do you think about this solution for a 3 way loudspeakers? I noticed that on the PX-600 brochure, Accuphase shows a picture example with this devices used with 3 way speakers system, with the exactly same design of the ones that I will start to build, take a look... maybe this says something? probably a good match? All components are from 2001, then, they are soooo vintage to worries about repair, recap, and etc, if considering very well cared units, the F25 is from late 90’s but was re-released in 2005. Let me know your thoughts about, very interesting stuff.... |
