Tactile Transducers

[seangoesbonk]

I have been thinking that a few tactile transducers may be a neat way to add a little pizzaz to the home theater experience.

I think I'll probably use some LM3886's in the datasheet recommended circuit.

And I am not sure about transducers yet. I found some by Stanford Acoustics for $36can ($24usd) each at Q-components
http://www.q-components.com/ (page 40 of the catalogue)

I was going to build all of the amps (4 to 6 of them) into a single enclosure, with seperate power switches, adjustable low-pass filters and volume controls.

Has anyone here completed a project like this? What transducers did you use? What amps? Any comments?

Any info is greatly appreciated.

well, i haven't done any DIY transducers, but i do have some commercials ones, and they are GREAT. for home theatre, they beat a sub hands down. mine can get down to about 5hz. (yes, i can see a few of you guys shaking their head. but seriously, they dont produce sound, just vibration, and at 5hz, they have output).

im using a 30watt mono amp for 2. transducers dont use much wattage, but they draw some juice still... i have a little fosgate mono block on them, and at full power, they dim the lights on my house (lights NOT on same outlet...). just build a very efficient, lower powered amp, and you will be fine.

I have seen some web pages where people have made their own tactile transducers from cheap woofers. It seems to have come out ok. Any thought on how to make them or why not to make them yourself?
