Tectonic Elements TEAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter
How many exciters are in the package for $19.25?
more expensive sound exciters say only one per package but this one is rated for higher watts so i am wondering if that price is only for one. Thanks.
Price is for one unit. Typically you would use two for stereo. If you have a very large surface you can use multiples to take more power and increase sound output.

Has anyone tried these as replacements for the drivers in Bertagni panel speakers ?
I assume you have a pair of Fisher model PL-6-U panel speakers. These speakers were a real innovation when they were introduced. The sound they created was not amazing, but their unique thin panel design was such a novelty that they attracted a market for them. If you were an audiophile, you didn't appreciate them.The HiWave HIAX25C10-8/SP 25mm High Power 8 Ohm Frog Exciter is a totally different concept and technology than the PL-6-U. The PL-6-U used two plates each as a pole and the entire plate vibrated when signal was applied thus creating sound.The FZrog Exciter is basically a voice coil in a frame that induces vibration and movement in whatever it is secured to. The glass, box, wall, door or whatever becomes the cone or panel. Generally the sound will depend greatly on what that panel or cone is.As an example, a 4 x 8 sheet of plywood will be better than a whole tree. A glass window will have better high's than a box which would be louder have more bass.To answer your question, I have no idea what kind of panel the Bertagni panel would make, but if you find that they do not make a good one, secure the Froggs to the walls behind them and enjoy, because life is too short to not have what you want even if you have to fake part of it.Good Luck
