While this is my now 2nd purchase of a NYNE Bass speaker, this one needs to drop the word pro from it's name. Two things about this new speaker I love; one is the new extended range, and two is the now back-lit buttons on the top. Easy to see & operate. Awesome! What I didn't care for was the lack of bass response that it's predecessor had. The older model had a small port in the back that simply kicked! This newer model moved them to either side, and the result is a lack of the sometimes overpowering deep rich bass. Don't get me wrong, this "Pro" model still has a ton of bass response, so for most, the level is correctly proportionate to the entire sound quality. I'm just a bass snob that prefers sometimes too much... so, I have to back the low-end off at times, but that's just me. All in all, a great speaker with unbelievably clean and loud volume inclusive of crisp highs and mids. You'll enjoy this one!
