When a self-respecting (and proud) owner of a home room wants to show off his media room the weapon of choice most usually happens to be in the category of "movies where stuff blows up." Certainly, most modern home theater systems have adequate subwoofers that can shake the floor a bit. But is that going to be enough for you? No buts about it. It won't! You need the very best of what modern ground shaking technology can offer. You need a tremor in the box, an explosion in a can - ButtKicker BKA300 or something comparable. For about $300 this little gadget will reproduce the lowest of the low when it comes to audio frequencies. A wireless design makes it very easy to install in any media room.
