Amp is two channel TDA7293 putting out a modest 50W per channel at 4E , amp modules contain DC protection and delayed switch on circuit and the bookshelf speakers are a two way bass reflex enclosure tuned at 63Hz , cross over point for the mid bass and tweeter is 4500hz , the tweeter have a L -pad attenuation of -1.5db to match the mid bass. over all speaker sensitivity should be 89.5db at 1W at 1M ...
Oh and the it uses a 2nd order linkwitz- riley passive cross over...

Welcome to the forum Aniket.

Great DIY stuff you have achieved here. Could you share from where did you get the overall design or starter guide sort to achieve the same?

If possible would be building myself a Sub-woofer.

Cheers!
