Query: To be honest, I was skeptical, but what took it over the top was the modular design (which allows you to add a sub and two other speakers wireless for 3.1 set up) and the Memorial Day sale price of 40% off on top of the already 20% (shout out to Amazon.com sales for making sure I got the sale price).
