DIY: Budget Bookshelf Speakers
By James Grahame
The DelSol is a compact bookshelf speaker based on a low cost $11 Aura NS3-194-8E three inch full range driver from Madisound. It was intended to be paired with the affordable Sonic Impact T-Amp, but it makes an ideal first speaker project for almost any low power amplifier.
Creator Jesse Ingham wanted to design something that was cheap, easy to build but capable of audiophile sound. The single speaker design eliminates the need for electronic crossovers, making the electronic part of this project as simple and inexpensive as possible. The elegant bass reflex enclosure measures only 6.5" X 5" X 8.25" and features a 2-inch bass port hidden on the bottom side. All in all, this looks like a great project get into the hobby of audiophile speaker building.
