Big bass from a booming sub is the cornerstone of any good home theater. Unfortunately, people that live in apartments or watch movies while the rest of the house is sleeping are forced to live without the realism a subwoofer brings to the game.
There is a great solution and it fits in even the tightest budgets. Bass shakers are a great addition even for those who already have a sub and they are easy to set up. Low frequency bass transducers are mounted under the seating in your theater or living room, depending on your system. They take the signal from your subwoofer output and vibrate, sometimes violently with the low frequency signal.
The realism bass shakers bring to your movies and games is impressive and it is one of the best upgrades you can make. It also impresses friends and to my surprise, are very friendly on the wife acceptance factor.
ButtKicker is the most common brand of low frequency transducers however lower cost alternatives that work as well are easy to find on Ebay and other sites across the web.
Bass shakers use an amp, which may be included in a kit, or you can use an old receiver, subwoofer amp or anything that delivers 50 watts. No need to worry about high quality power here, any old amp will do.
Stop living without the bass you so badly need to maximize your home movie experience and install bass shakers now.
