I replaced a blown sub in an off brand case. My first night out with it, it rattled all the low frequencies better than ever and didn't seem to be prone to distortion and clipping. I was using a Behringer 3kw amp with extra signal processing. The comments were impressive from my clients.

After 14 years my JBL Mpro bit the bullet. I decided to take a chance on buying a speaker without hearing it. Eminence has a great reputation so I rolled the dice. The Eminence Imperio fit perfectly, and the sound is amazing. I opted for the 4 ohm version (also comes in 8). If I was to describe the difference between it and the original, I would say it is tighter and less rumble. It punches harder than the JBL did. I have not one complaint with the Original, I certainly am not complaining about this one. I was looking for a replacement, I think got that and more. I would recommend this American made product to anyone.
