Default LX-mini Crossover Article

At long last, I have completed the LX-mini Analog Crossover and posted
in in the Article section of FIRST WATT

It will serve as the documentation and assembly manual for the kit which
will soon be available in the diyAudio store.

Enjoy.

I've been patiently waiting. And it's going to be just in time for a nice speaker project. This is super great!

LX-mini Crossover Article
as always ..... BL , centered around 8mA ....... that number being in sweet spot regarding xconductance , associated resistor values and dissipation of part in circuit

however , this one of rare opportunities to toss in whatever you have of Toshiba leftovers (yup- GR and V , too) .... as long you're willing to do some sorting - higher Idss in lower position , lower Idss in upper position in buffer cell ..... and then play with source resistor in lower half , to tidy output node voltage level

Dear Nelson,
Every one has some opinion on LX-mini or open baffle.
We will miss papa amps if we built LX-mini because it requires 100W+100W.
we are running full range with 20W+20W.
So what is your point of view on LX-mini or open baffle with probable FET class AB or chip amps.
It is just some curiosity.
Thanks.
Nag.
