Class-A linkwitz Active Crosover

[Rixsta]

I was searching for a class-a active crosover
and found this web page might be of intrest to some people here

http://www.soundlabsgroup.com.au/lcaudio/lc_audio_active_crossover.htm

im wondering weather it would be worth building it
would the sound be good
or would it be better staying with op-amps like the
linkwitz-riley crosover on rod elliot's website

scince my amplifiers are class-a i dont see the point in putting
op-amps in the signal path

You can bias an opamp into class A.

Search the archives - lots of posts on this topic.

The price seems a little steep.

Thanks for the replys

I may bias my op-amp's into class a
i had a search on google and found a site
seems a good idea i think
it's not too hard for a electronix beginner like me..

im not planing on buying that crossover, if you look at the bottom of the page they give away the schematic diagram

The x-over freaquancy's or what ever you call them can be calculated using ESP's crossover calculator

so anyone out there who dosent like op-amp's you could
give it a try.

Descrete class-a linkwitz-riley crossover
i think you would call it
