What aubot using a prefabricated kit instead of trying to combine speakers by yourself?
If you buy a kit you get everything needed and you then only have to build cabinets by yourself.
Scan- Speak, Visaton or any other manufacturers are selling those kits...

If you lateron are happy with your new hobby, then you can go on buying somme good books about speakerbuilding.
And read and read and read...

And then you may be into measuring speakers by yourself, then you can think about combining speakers yourself...

It's a loooong way to go until then...

MPOV...

greetings, B.

SEAS, ScanSpeak, Vifa, Peerless are just some of the good ones.

Sure.

The wire's diameter will be dictated mainly by the power handling of the coil in mind and your series resistance goal. How many turns? What are the difference between cores? I see that you're an EE student, these are 1st-year level questions the answers to which are found in any good physics book... or you could do a google search. However, most books don't tell you of nonlinearities like core saturation -- a bad thing just in case you didn't know. So, air core inductors are prefered.

I think at this point you may want to consider building a kit. Designing loudspeakers, "high quality" and newbie cannot all be used in the same sentence.

Build a kit as Benny suggested. Also, have a look at the following books.

Go to this website:

Click on "Techincal", then in the lower left-hand corner, click on "Pop!"

Here is a plan for a 2-way shielded loudspeaker for approx. $100


This should be a good starting point.

Good Luck!
