Recently, I have been taking some online courses on acoustics and speaker building, and I built (from scratch) a pair of bookshelf speakers as a "school project."
Marius Tanasescu is the creator of a series of online audio courses on Udemy.com. I have finished his first course, Audio 101: Speaker Design Basics, and Enclosure Basics, and decided to build a basic pair of speakers to apply my learning.
The drivers are GRS 8FR-8 units I bought from Parts Express for $15.98 each. These are 8", 8 ohm, 60W units. To keep things simple for this build, I chose to use full-range speakers.
Each speaker is 15.5" high, 10.25" wide, and 13.5" long, The enclosures are made from 5/8" (16.13 mm) particle board. I covered the enclosures with black and woodgrain-patterned self-adhesive vinyl.
The final product sounds great! I've tested them with classical music, some country, a little rock, and a couple of movies. The big cones really put out sound; even at low volumes, they still dominate the room. Being full-range drivers, they are a little weak at the extreme ends of the frequency scale, but still sound good.
For my next project, I am planning to build a subwoofer to add some of the missing bass to this setup. In the future, I also plan to experiment with different paints and other finishes to get a system that looks as good as it sounds.
P.S. If anyone is interested in taking any of these audio courses, they normally cost about $95-$100 each, but I would suggest using the new student discount at Udemy to save (often 85%+) of money. If you're already a member, just wait--sooner or later they usually go on sale.
