Dayton Audio DAEX25 Audio Exciter Pair - Sound Exciter Pair Audio Transducer - 5 Watts RMS, 8 Ohms Impedance - 2 Pack - Turn Any Surface into a Speaker System

Quality sound, Quality performance, Easy to install and can be placed anywhere.I used the end tables, my coffee table and then put together to pieces of decorative wood art behind my sofa to make the full spectrum of sound. They work perfectly!!!

I was looking for rear speakers for my motorcycle, a 2003 BMW R1200CLC, when I came across the Dayton Sound Exciters. Since the price was right, and REALLY didn't want to cut holes in the top case of the bike, I figured I'd try these... if they didn't work, well, I'm only out 3 cups of Starbucks coffee! Hooked them up last night, and although they are not as powerful as my front speakers, they are plenty loud for the passenger when I set the fader to have more volume in the back, (so my wife is now happy). (Note: part of the volume thing could be my fault - instead of using BMW cable ends, which I didn't have, I used Radio Shack butt connectors in the wire harness...) Anyway - frequency response thru the fiberglass/ABS plastic top case is very good, and I recommend them.

I haven't put these in their permanent location yet, but I have tried these on several different types of surfaces. I would have to say that I am definitely pleased with my purchase.Note to future buyers, you will definitely need a small Amp or EQ to help get the sound you want out of these. I purchased the small EQ that was recommended and it works well. For supreme sound, I would recommend running these both off of 1 channel and use a slightly bigger driver on the other driver to add more depth in the quality of sound. You don't need a lot of power to push these so they are perfect for camper installations. Added bonus is that most campers are perfect surfaces to amazing sound projections.

Love these guys they work great and are fun to find things to use them for

The media could not be loaded. I purchased 2 packs to use with two 2ft x 2ft sheets of polystyrene project board and 2 sheets of honeycombed cardboard (also known as palletboard). The exciters work well and the sound they produced is nothing short of amazing. They are wired in parellel producing a 4 ohm load on my Denon receiver. Volume levels needed to produce audible sound are around 30 on a 1-100 scale and work well up to 60 or so. Anything louder seems to invite clipping as these speakers are rated for only a small 5 watts of power. During setup of the Denon I did not notice that my receiver switch my stereo speakers from small to large. Playing “Take Five” at around 65 clipped one exciter and rendered it useless. Since then I’ve been ginger with my settings and have played them for many hours without issue. I’d highly recommend these exciters for small areas or low volume applications.

These things are pretty neat, however the adhesive on them isn’t good for more than a couple uses, after that it’s hot glue gun time. I bought a small amp to power these and stuck them to the headboard of my bed, completely devoid of bass, but still cool. You can use them on all types of different surfaces but the best material I’ve ever used (sound wise) was styrofoam. If you stick one to a two liter and the other to a sheet of styrofoam you’ve got yourself a radio with bass and if you made sure to buy a Bluetooth amp you can control it with your phone.

These are really fun - you can turn any surface into a speaker. I mounted a couple in the attic on the reverse side of my ceiling drywall. While 5/8" drywall clearly isn't the best medium for these, the sound is still quite satisfactory. Bass is particularly rich, while the treble has a bit of a "tinny" sound.I did have some trouble with the attached adhesive pads on one of the two, which refused to stick even after thoroughly cleaning the area. I ended up gluing it with Liquid Nails, which appeared to do the trick.On a medium such as glass (the key is thin, light, and rigid), you're likely to get much better sound quality. However, it's still a fair bet that these will do better in the bass range.

If these are place on something thin and hard, like tempered glass, they sound great! Careful on placement, it's possible to get some resonance in your medium that won't sound great in the audible range so test placement might help (generally asymmetric placement too) I stuck them on some thin tempered glass about 1/16" thick and they are powered with a little class a amplifier and they place wonderful music in higher frequencies like classical violin, gypsy jazz, Etc. Since the medium I choose to stick to is hard, not much of a chance for bass and lower notes so some music sounds horrible. Best to pick your medium off of the type of music. Just remember that this item has to be able to push a compression wave into the medium and if it is soft, it will absorb the wave versus propagate it. I would buy these again if I needed more tactile transducers. They also make tactile transducers purely for bass.
