HI

I'm new to audio world and just tryng something for cheap. How big box do I need for two 40W rms midrange and tweeter combo and one 40W rms sub?

 

Thanks

All combined or on their own?

 

If you want to go true cheap. Look at your local classifieds or thriftshop and get a pair o cans for 10$

Do you just want something that can physically hold the speakers, or do you want to build a tuned box so they can reach their full potential?

 

Speaker housing design is a deep rabbit hole.

Combined 120W rms. Only thing I know is that I want open box. I know that this is going to be rabbit hole but i just want rough estimate about volume.

You need to look at the speakers spec sheets. They will generally have box recommendations.

And even thse methods are more like rough guestimates that bring you close to a good enclosure, but ifyou want it to sound really well, you will have to test, a lot. Also then starts the problem with the crosover, although nowadays, you can use a DSP and spend a couple of days with that.

 

Its doable, but even people that do that professionally for decades can spend months optimizing just the enclosure.

If you're just getting into the world of audio, you should be buying pre-made speakers, even if they're used 

In practice good speakers need $100,000+ worth of engineering work and design put into them. It is VERY VERY hard to do good enclosure design and it's all been computer aided for a long time. 

It isn't 1970 anymore where people - and companies - were basically winging it. A lot of sound quality comes down to design, NOT the size or materials used and good design costs a lot... and needs MANY MANY MANY speakers made to justify its cost.
