Parts Express Speaker Project (2")

From the Parts Express catalog:

This 2" driver is packed with features that make it unique for its size and price. The driver has a 1" voice coil on a Kapton former, a unique plastic spider, and a copper cap over an extended pole piece. These characteristics ensure good power handling and extended frequency response. The 2-1/4" square frame woofer has a built-in rear gasket to allow easy air-tight mounting. Other features include a paper cone with specially designed dustcap and a treated cloth surround. Quantities are limited, hurry!

This project was completed unsuccessfully. Initially attempted implementing these drivers in an open baffle array configuration.  The sound was very thin and tinny and no mid-bass.  Then placed them in a box, as shown, same results. At $.98 per driver, this project was fun and and provided interesting results.



If you have completed a project with these drivers had have achieved good results, e-mail me I am very interested.
