Query: Good system given what you pay for it.

I brought this sub woofer when it was $100 and now it is on sale for around $70 during the Black Friday sale.i received the speaker fast and it was easy to setup and connect right out of the box. I wasn't looking for something complicated and all I had to do was to insert RCA cables and your done... There is a pass through option for if you need to run your front speakers through the woofer as well if needed.I had 5 speakers from my old system and just needed a woofer to complete the set.For the price that you pay, it is a good speaker to get if you want some bass to complete a small theater room setup. It was recommended to place this in the front near the screen but it works better in the center rear.If you're looking for a high end sub woofer to shake the walls, this isn't for you, but if you're looking for something low cost to get the job done, this sub woofer works.
