Hello from PA! (Project suggestions?)
Hello everyone!

I am new to DIY audio and am very excited to have come across this site. So far almost all of the topics are above my head but I am still enjoying reading the topics. I am attending school for audio electronics but so far we have just learned basic electronic theory so I understand how individual components work, but have yet to understand how things work when put together (besides basic resistor/capacitor series parallel combinations). But I guess this is why I go to school :).

I am currently building my first set of speakers and am having a great time doing it. I would love to be able to use these speakers in my room at school, so I would be using my computer's sound card as a source. What else would be needed so this would work? Amp and so forth? I would love to build any components myself so if anyone has any suggestions of projects that are basic and at a reasonable price range I would really appreciate it!!!

Also if there are any websites that can be suggested in the intermediate level that explains amp and other audio equipment basics I would love to read them. Most sites I have come across explain the basics (like what a resistor is) or are as complicated as the topics on this site. Is there anything in the middle??

download his articles and build, learn and have fun while you read or solder.

Welcome to the forums.

The minimum is a power amp. You can use the volume control on your computer, but I find it convenient to have a physical knob handy. You could use either a passive attenuator (dual gang pot in between sound card output and power amp) or a preamp.

Great source of information and projects:

You might have a go at some things like open baffle, 3" full range drivers, mini subs (not necessarily all together).

You might also look at using a computer digital active crossover. Check out - a member of this forum.

Also keep in mind that diy amps aren't always cheaper/better than some amps that you can buy already made. IMO speakers and preamps are the most cost effective DIY projects. A $1k can be built for under $100 and a $5k speaker can be built for $1k.
