My lord, what a piece of junk the BIC F12 is compared to the Energy EWS-M8! All it has going for it is volume, and the ability to go slighty deeper. Otherwise its a muddy, bloated, inaccurate farce.
The EWS-M8 is very tight, fast, and accurate, and its not even "broken in" yet. I bought the BIC F12 thinking I needed a bit more "presence" that a big 12" would bring to movie sound effects compared to the tiny 8" sub. Yes, the BIC F12 is as loud as I can tolerate and will rattle my house at 40% volume. But then I just decided to be a little daring and turn my EWS-M8 up to 75% volume instead of 50%. It matched the volume of the BIC F12, but WITHOUT sounding like a flabby bloated muddy mess. Both subs were tested with 120Hz crossover on a new Yamaha receiver.
The best example of this I found was the Ferry scene from War of the Worlds with the alien "horn" sounds. On the BIC F12, they sounded flat, dull, lifeless. On the EWS-M8... they sounded TERRIFYING as intended. My wife thought so too. Everything else I threw at it, the EWS-M8 just sounded way more accurate and controlled.
Music was no contest. The EWS-M8 is far more musical. The EWS-M8 also mixed in much better with my Yamaha bookshelf speakers, sonically. Now I see why the "suggested" retail price for the EWS-M8 is $800 (I got it for $300). The thing is bloody amazing for a 9" square box. The BIC F12 does win by a hair with the depth charges in U-571, but only because it can go a little lower in Hz. Every other movie sound effect or music, the Energy just wipes the floor with it, for 1/4 the size, half the weight, and only 1/3 more price.
I am never buying a bass reflex sub with an open port EVER again. Volume is all they have going for them.
