Review: Deep supporting bass ! - Liked everything, the bass is comforting to the ears, gives me luxury car vibes and its very clear 😍 ive used the sealed enclosure box dimensions provided 👍🏼
Review: I had a Planet Audio sub in a small sealed box that I also bought on desertcart. I replaced it with this one and was worried that the airspace would be too small for this. I was really impressed at how much low bass this put out even in a small sealed box. I am considering making a larger enclosure. I am running 250 watts RMS to this sub. I don't think you could beat this for the money. I paid $45 for it. Very impressed.
