I was initially skeptical of this subwoofer due to its size and 10 inch subwoofer. However I am very impressed with the low frequency, thumping base, and Power it had for my outdoor patio. I'm driving it with a Nobsound 300w subwoofer amp. I'm actually thinking about getting a second one not because of inadequacy, but to satisfy my need to be the loudest on the street and upset my neighbors LOL

This outdoor subwoofer is pretty awesome! Wanted to add some lows to our outdoor system. Placed it on a paver in a garden by the pool and this fills the whole backyard and top deck area. Pairing this with a OSD 200 watt subwoofer amp and it performs very well. We also used this on halloween and hid it in the front garden with low rumbles and scary music and everyone loved it! This has been out in extreme heat and humid weather, heavy rain storms, sprinklers, in the snow in the winter, and still performs perfectly! I do wish this came with a grille to cover the exposed driver. Animals and bugs like to hide under the subwoofer. Wish there was a grille to keep bugs out from going underneath the cabinet. This subwoofer does have nice weight to it, but since it's a plastic base, I recommend putting rubber feet on the bottom, this driver moves alot, and the cabinet will buzz on the paver. Adding extra weight like a potted plant on top will help. It's been enjoyable, music and movies are much improved! Watching movies outside like "Hamilton" which has lots of bass in it, You can definitely feel some of the rumbles. Can't wait to try "Maverick" outside when it comes out. I think this subwoofer out performs Polk's atrium sub in terms of more power, more weight, beefy build, 300 watts and cheaper price. This has definitely been a nice add-on to our outdoor audio system! Way to go OSD!

Pros: Attractive design. Good weight. Great sound. Fills whole backyard. 300 watts. Cheaper and outperforms Polk atrium outdoor subwoofer.

Cons: Wire pig tail is a little short. No grille for driver. Buzzes on paver. No way to keep animals/bugs from going underneath cabinet.
