I bought this to replace a stock that came with a soundbar. The stock one had very muddy sound and just didn’t have any depth since it was powered (barely) by the soundbar.This one adds a whole new layer to the sound being produced since the bar doesn’t have to worry about providing any power to the sub.The set up took less than 10 minutes and the out of the box settings were sufficient to show off the missing elements from my original set up.The many different connections available on this sub just add to its versatility. I use it as part of a desk top computer sound system. It would also be great as part of a home theatre setup for a smaller room where you want the deeper elements without taking up too much space.I would buy again if the need came up.
