Price to quality these are excellent. They are not brilliant, first off. But what they are is a very good sounding, very nice looking little driver for less than £20. Used in an active speaker build (sealed enclosure 250 x 160 x 220mm) with a Lepai LP40PA amp and Dayton 1" tweeter they sound impressive as they look. Would recommend these for any budget built. Sure they aren't perfect but what is for less than £20?

These are great drivers, I've used them in the past also. it'd be good for SoundsImports to show examples of use and to provide usable data such as fdr and zma files for all the products. Thank you for asking feedback. Regards
