- Surface Transducer - Large
Surface transducers give you the awesome power to turn almost any surface into a speaker. They're essentially just a speaker except instead of a cone, the coil is attached to a pad that conducts the vibration into whatever you press it against. Hook it up to an audio source and press it against the nearest table, wall or cardboard box. You can even put it against your head and play music directly into your skull (the ultimate surround sound). This transducer comes with an adhesive magnet that can be attached to the base.

Core Skill: Soldering
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I need to keep testing
It's a nice product for sure. I ordered 3 of them, first to do a little immersive sound system connected to furniture of a room. Second project is to do a plate reverb. The only thing I dislike about this unit (and that I need to keep testing) is that it seems to have a serious ringing resonnant frequency around 3k, which is quite unpleasant. It did occur almost everywhere I tried. The 2 options I found to counter this problem so far were with experimenting with different connexion plates attached to it, or to use an EQ to kill the resonnant frequency.
