Q: Have you seen Aviom PLF-1 tactile platforms? Same idea--you stand on the platform, which vibrates, and you "feel" the low end thru your body. Well, the PLF-1 costs $750, and that's just the platform and the transducer. You also need an amplifier. The matching BOOM-1 amp/processor costs $700! So that's $1450 for the system.
Yeah, right. I decided to DIY.
I bought these three items from Amazon for about $88:
- Dayton Audio BST-1 High Power Pro Tactile Bass Shaker 50 Watts: https://www.amazon.com/dp/B01CDDPJTI
- 100w mono class D amp module: https://www.amazon.com/dp/B07H337F4L
- 24V 6A AC Power Supply: https://www.amazon.com/dp/B01CYIFOHE
Works great, exactly as hoped! The platform is 30"x30" 5/8" cabinet-grade plywood. The height of the "feet" is 2.5", making the top surface 3" tall (I guess I can leave my platform heels at home). I left space for the legs of my mic stand so it can snug right up. I send signal to the platform's amp via the headphone out of my Line 6 Helix, and that provides an easy volume adjustment that's independent from the main output for the speaker cabinet.
I'm going to try it at our club gig tonight, and I'll post results. I just have to watch I don't accidentally step off the rear edge!
