Calibrating Transducers

post #1 of 3
Thread Starter 
I just installed a Buttkicker LFE kit to my sofa in my media room and am contemplating adding a couple more transducers as well. However, the instructions are very light on how to properly "tune" the Buttkickers. Any suggestions on how to get the right amount of punch without overdriving the transducers?

think it has a lot to do with personal feel when it comes to this.

at first i was super excited and had it set too high, half way through star trek, i felt like i was going to hurl!, takes a lot of time to properly tweak them, i watched many movies, tweaking it up and down until i found a volume i was satisfied with. Definitely not a easy task, tweaking these to be just right.

That was the movie, not the transducers. That movie gets me queezy normally tongue.gif .

If the OP is serious about his question, you should also consider the LFE mix adjustment on your receiver, adding or decreasing gain in the sub channel on you receiver, AND placement of the transducer on your chair or sofa. Others have found that placement is just as important as volume or gain on the amp. You will have to spend time adjusting the variables to find your ideal level of shake and sound loudness.

A few key points in your install are:
1.What do you want to shake? Your whole body or a body part? Install in proximity to that.
2.Isolation of your seat from the ground gives more precise feedback, your seat should be able to "spring" with the transducer, not prevent it. this will also allow you to turn the amp down for the same amount of shake.
3.High cutoff setting, between 70 and 80 reserves the shake to mostly powerful sound effects. If you prefer rumble infused music, set it high or turn it off.

The most tedious part of calibrating the BK system is getting it to "blend in" with your current surround speakers. It takes time to test all the different combos in channel gain and volume levels on receiver and amp. But once you know your volume ranges that your comfortable with, just be systematic in finding the sweet spot of your particular acoustical environ. For what it's worth and worth every penny.smile.gif
