Use the IW620's with a crossover in an enclosure and voila: Great Bookshelf Speakers!
March 25, 2014
Successfully built awesome sounding ported bookshelf speakers out of these economical IW620's. Total cost for two great sounding bookshelf speakers was $85.
See the build thread at audiokarma.org forums here:
Pros:Extreme low cost.
Cons:Not a con, but a caution when using these in a DIY speaker build, adding crossover circuits. Don't unsolder at the tweeter connection. The tweeter plastic will melt. Instead clip the thin silver wire right at the base of the capacitor.
Best Uses:DIY bookshelf speaker project.
