Cabinet box size for 3.25 inch speaker and a 1.5 inch twitter?

There are on line calculators for box size but you need to know the Q;s of the speaker involved not only the size...the resonant frequency, lowest frequency out put etc...bass out put determines the size of the box not all 3.5 speakers are the same....you can also just take your chances and guess, sometimes you can find the exact same driver on line being used in another speaker and just copy the size of the encloser being used in the on line example...the tweeter does not matter it is only the bass driver that determines size so if they use a different tweeter that is not so important...check out Tang Bang Drivers for good quality in small sizes...

the suited hollow length may well be counted some on the speaker layout. i might degree the audio gadget, or use a template in the event that they contain one. For a sealed container you have the prefer to make helpful there's a brilliant sort of overhang of the speaker over the lip of the hollow so which you do no longer finally end up with a (noisy) air leak there.
