Default A low cost DIY chip based active filter + Amp circuit needed

1. "Active" filter for two way speaker . Bookshelf only
2. A 10 to 15W "amp" to drive the two ways speakers; prefer chip based to start with.
3.Both the active filter and amp will be mounted together.
Can anyone suggest a suitable DIY design.There are many links shown in this fourm but its not that easy to ship modules/components to India.
Hence prefer a commonly available component design.
Thank you.

and construct the active crossover and an amp of your choice but beware not to blow your small power rated speakers if at all. Select some TDA power amp chip. TDA 2030

The tweeter amp needs to be of double the power than the driver.

There's a past number/issue of the Costruire Hi-fi magazine
sommario chf 155
which you may get in a downloadable/viewable format through the net
It's mainly a Fast ( subwoofer+ full range) , the sub being a little 13 cm in a
double reflex enclosure, the same holding the 8 cm fullrange inside, both powered
by TDA 2050 and OPA2134 ( ??) for L/R crossover at about 160 Hz.
Both drivers are also italian, so...
