Need help for building 8" subwoofer box

pradeeppk · 14th October 2009, 03:58 AM

I have one 8" 60W subwoofer and i am going to build an amplifier around LM3886. This is first time building a power amplifier project. I need a design of cabinet and your valuable suggestions.

Welcome to DIYaudio.

You'll find many threads and projects on subwoofers and chip-amps like the LM3886. I'm going to move you to the subwoofer forum so you get some better exposure.

Enjoy!

What we need is to know the parameters of the speaker. At a minimum we need Vas, Qts, Fs, Xmax and power handling. Without these no one can help you.
