S Roy (verified owner) –
One of the BEST driver in this size. Made a 2 way bookshelf in a 5.5 lit box and paired with dayton nd25fa tweeter. Output is fantastic and the bass is superb ! Though I am using it with 2.1 amp of FX Audio but don’t feel like cranking up the sub volume.
BUT unfortunately the price has been increased by double now. Thought of buying some more driver (same) but I need to look for an alternative now !!
