I think that you like to build a subwoofer for very low cost.but you need good quality bass.yes it's possible.. With my 2 years of experience i can say that we can build a good subwoofer for low cost. What should you buy to make cheap subwoofer ? 1st need to buy a speaker . Actually a low range speaker .also called sub speaker , woofer etc. Don't think about speaker size or price. The bass of a subwoofer not depend on speaker size.but yes you need a big subwoofer for big sound. Every small subwoofer can't connect with large amplifier . Then it will heat up.can even burn quickly . But in this topic we are talking about a small subwoofer. Like 10- 20W rms output . Maybe you will think that this will be a very weak subwoofer with a 10W amplifier . Actually no.. Do you know that any car amplifier can't deliver more than 20W per channel.because they can't .. Yes i know that you imagine about a big car subwoofers which can shake you body. That is correct.but that car subwoofer have a different method to power that big amplifier .i will tell more about that subwoofers in my next post. For now just keep in mind that almost all car audio player deliver only 20w max rms.so it will not weak.you can here music with that players while you drive. So now i will going to explain how to build a 20w subwoofer. Now buy a sub speaker like 5-7 inch. As your budget. As i said,you can get same bass quality even though it's 5inch or 12inch.yes please trust me. If you have a doubt you can imagine about a deep bass ear phones.they have same quality bass even though it's 1cm speakers. Now you have to build subwoofer box.
