Well my theater seats is broken down in sections and is not one solid piece so I figured the best way to do it would be to build a platform for my theater seats to sit on then I would put rubber isolators between the platform and carpet floor.
I ran across a good deal on 2 used Buttkicker lfe's with the 1000 watt Buttkicker amp and wired them in parallel as recommended. I originally was just going to build the platform to JUST be big enough to place the seats on but once I got going it kept getting bigger and eventually ended up to a beautifull Mohagany stained clear coated 12 ft x 7 ft platform. I used 3/4" cabinet grade plywood for the top and framed it with 2x4s and it must weigh at least 400lbs or so.. I'm just guessing but it's heavy.
So really I don't think 2 lfe's are enough to shake the weight of:
1. ~400 lb platform
2. ~200 lb theater seats
3. ~(200 to 700lb) people depending on how many watching at a time (seats 4 total)
It produces a nice rumble but nothing like the youtue vids I've been seeing as well as people on the forum have been talking about. I'm just not completely satisfied with the results from all the work I've put into this project so I'm wondering if there's too much weight for those poor things to handle or what?
I don't want to shell out more money for 2 more (kind of stretched my budget getting 2 in the first place) so I was wondering if I can run some Aura shakers inside the seats and keep the 2 Buttkickers on the platform or add Aura shakers to the platform or what?
I know I can run up to 4 lfe's on the Buttkickier amp but can I run Aura pros with lfe's on the same amp or is that not a good thing to do?
How did you construct the riser? You want the platform to be "suspended". The way to do that is to use a frame that is the height you want and then use "joists" that are shorter. Then mount them so the tops of the joists are level with the top of the frame, and the bottoms of the joists are *not* touching the floor. This will suspend the platform and give it some spring. It's a lot easier to shake it if it's suspended.
This how I constructed my platform. I used 2 x 8's for the outside framing and 2 x 6's for the joists. You can see my installation here:http://www.avsforum.com/avs-vb/showt...0#post21093230
On the following page of that thread page, I described my set up and the benefits of tactile motion. Further down there are more pictures of the final install.
I use Crowson tactile actuators placed directly beneath the seating. The seats are also sitting atop rubber motion isolators. The combination of the suspended riser and the motion isolators provides shaking/vibration to the entire riser and the chairs. It can get really crazy. The other night, my brother-in-law was over and we watched Thor
. There is an enormous amount of deep bass in that movie. Afterwards, my B-I-L's comment was, "Wow! That was a lot of sensory input!"
Also, I described how I set up the signal-flow for my system here:http://www.avsforum.com/avs-vb/showt...3#post21687493
Good luck with the Buttkicker LFE's.
