Pros - response to 3hz?
Cons - the drivers make sound, and the FR wont be flat.
The force probably isnt as strong.
Installation is more involved.
Not as aesthetically pleasing.
Fs in the 20hz range vs 9-13hz for the Buttkicker
All this in mind, im thinking i might try a Buttkicker instead. Am i missing something?
Steve....good question....I've experienced butt kickers in personal theaters and at AMC.......no comparison to the BOSS.
The BOSS makes the entire floor beneath you move starting at 3Hz with authority and teeth start rattling at 11Hz to 22Hz and gently rolls off around 30-40Hz depending on how the LPF is setup.
The experience has to be felt to be believed.
Below is a video of one of the JBL's in action in the back riser after I first constructed it. You can see respectable excursion is achieved with only 80 watts starting at 2Hz.....you can't feel it until about 3Hz when sitting on the platform, but hey, I'll take 3Hz TR any day, especially for less than $100 plus an amp. This excursion times 3 (3 drivers there in the back riser), makes the entire riser respond on command from the JBL's. The front riser is the same experience.
Think of the entire row of seats sitting on a bed of air and that row of seats responding to every wave of low bass energy that moves the earth beneath you to get an idea what the experience is like. I don't get that feeling with buttkickers attached to my chair.
Regarding aesthetics.....yeah, buttkickers are totally hidden....hard to beat. But, with a little carpet on the mini-riser or if you already have a full size riser, the BOSS disappears and nobody knows what they're about to experience until the ground starts moving below them.
My daughter was home from college this weekend and had one of her friends with her. It was her first time in the theater since the BOSS upgrade. They were in the back row, I was in the first row. I queued up "WOW - Pods Emerge" and started playing it without saying anything. After about a minute, when the demo scene was quiet momentarily, I turned around to ask her if she liked it......I didn't have to say a word to know the answer. She was staring at the screen with her mouth wide open oblivious to the fact that I just turned around and was talking to her....Priceless!
After a few more demo scenes, I stopped and lifted one of the chairs to show her the subwoofer below. She said "Oh my gosh, I had no idea, that's crazy, it was like I was riding in the car", right after we watched a demo scene from the movie "Getaway".
