Review on Enhanced SEO: Earthquake Sound FF6.5 6.5-Inch Front Firing Subwoofer by Coby Hall

Good looking construction. The controls and ports worked as advertised. It was more than I expected despite checking the measurements. The sound was too loud and loose for my application. I had to turn the volume down just above minimum to mix the bass with what was coming out of my other speakers. A good choice when you really want to "feel" the bass. If you want to hear the sound that's out there, you might want something with a thicker sound and a sealed enclosure.
