Just got my par of ND65-4 today. Really impressed with the speakers bass quality and would give it 5 stars right there, Though I wish it had a higher/clear treble sound since there is music where is sounds bit muddy on the higher tone whichs is why I give it 4 stars for them :)

This is an awesome little driver for boomboxes. Tune it to 60Hz with a PR or a port and rock on. A true full range driver with crisp balanced sound and a surprising amount of punch if tuned right.

Al di sotto delle aspettative, decente nei bassi, deludente negli alti, soprattutto in rapporto a quanto riportato nelle molteplici recensioni

I use them in 3L vented small radio box and sound is very good! But at higher frequencies, they are directional .
