Inexpensive DIY Speakers


I have a friend that is a shop teacher that wants to put together a project for students. The idea is a good 2-way in a moderate to large enclosure. We're trying to keep the cost down. The students will build the cabinent and do most of the construction. The drivers don't need to be audiophile quality, just good.

Thanks for the compliments John_l and Evo845. Actually, I have reread the question in this thread, and have even done some more thinking. A good thing to try here is to run the midwoofer full range. It would: save money(no inductor needed), let the driver perform better(a lot of us are discovering this), and also be a better way of ameliorating the need for the resistor on the tweeter leg(via less loss to this driver). This solution would be more beneficial when employed with a 6 1/2" driver as opposed to an 8"(my opinion...). Don't give up the capacitor to the tweeter however, it keeps the tweeter alive and well. As I said, I reread the thread and did some more thinking. I was thinking that what I had recommended could possibly too expensive(even at $125). If the money is there, please follow the path I previously outlined. I guarantee a pleasant surprise. If not, here is another variation. Build the same speaker, using cheaper parts. A cheaper tweeter(Audax, Seas, Vifa, etc.) and a cheaper midwoofer(same companies). Please keep the soft dome tweeter, as I feel it is money well spent. Metal domes can be very strident, this setup with its minimal crossover would accentuate that. The step back on the other driver may mean you will be using a paper cone, etc. In the crossover area, do not go below OF copper for wiring. But, you could step down to a Solen cap. And you could step down to a more run of the mill(suprising how many high end speakers use these) binding posts. I do believe the potential is there to keep the cost of this project around $50 or $60, if necessary. Again, GOOD LUCK!
Thanks Trelja, the amount of detail you offered should qualify your post for more than a +2 rating. I am tempted to build a pair of these myself. Your effort is appreciated.
Go to the single driver website at http://melhuish.org/audio/index.htm Talk about keeping it simple! Inexpensive too. I am playing with the discontinued 4 x 10" 40-1297 full rangers. These are $5 each and make music.These won't have the deep bass that highschool kids might like but for not much money you have some really good sounds. There are plenty of DIY articles on the site using speakers from other manufacturers ( like Fostex ) as well. Highly recommended
