I didn't even bother to note that the resonance between 50-55Hz is a fairly serious anomaly. Just looking one would think that this sub is tuned to 52Hz.
I have to tread lightly because you decided to have someone in your family get an entire EMP Tek set-up. Why you didn't have someone else on your staff test this sub mystifies me. I saw all the reviews you have done for EMP TEK. EMP TEK is one of your regular advertisers, no wonder they wanted you to be the first to test this product. IMHO in the future you should recuse yourself instead of continuing to review EMP TEK products.
All the same I don't think there is any rush by other sites to highlight EMP TEK products. In a shootout at any of the different prices (especially $499) there is some pretty good competition.
In the end it still comes down to cosmetics and WAF, and not performance.
PS How does one find out when you are having a promotion like the one on this product?
PPS Do you have any idea if EMP TEK is going to take any steps to improve its quality control? No matter the price a subwoofer with the wrong driver is really sloppy.
