I did really like how it sounded in a sealed enclosure. It wasn’t until i ported it that the problems occurred. I had it in 1 cube at 31 HZ port tuning when it failed and I was bassing it pretty hard. Very very good output sealed for a 300 watt 8. It’s hard to find a 300 watt 8 that could actually keep up with this Dayton on straight performance. I’m disappointed that the durability isn’t there. It should be for 135$. The AB 8s, Skar 8s, massive audio 8s and sundown 8s can take a lot more punishment. I would never recommend that anyone use this in a ported enclosure. It will not hang in a car audio environment playing music in a ported box.
