The QSC KW181 is a 1,000 watt 18” subwoofer that has a class D power module. This is the type of sub that will make your thump sound better than it really is. Just using this to listen to a previously recorded song that we did really shocked us because out of all of the other subs that we have used this is the one that exaggerated the low end, which could be a good and a bad thing if you are not careful. This sub is lightweight any easy to transport, it is also very durable and will last you a long time. We have bumped this amp so many times because for certain gigs we take a smaller truck and for some reason we don’t have good luck with unloading and loading it up. But it still keeps working perfectly but it does get nicks and scraps pretty easily though. There are handles on it that make it easy to carry especially if you have to carry it a good ways to get it inside. Because with it weighing almost 100 pounds you don’t think that any handles could help with that load it will put on your back and legs but the weight really isn’t an issue with the KW181.
The maximum peak is 135 decibels and the driver size is 1 x 18. It gives you all of the drive and power you need for your whole set up. There are even dual balanced inputs (XLR) and dual balanced outputs. The frequency range is very good (40-112Hz), and for the price of this sub it could be one of the best options for someone looking for a new sub for their set up. If I had to get rid of any sub that I had and just keep one this would be the one that I would keep just because of the sound it provides and how durable it is.
