Dayton Audio DAEX25FHE-4 Framed High Efficiency 25mm Exciter 24W 4 Ohm

The media could not be loaded. Accidentally discovered this beautiful gem of a product while looking into building my first set of speakers and I'm very pleased with the amazing results in the sound quality of this specfic Dayton Audio Exciter. After doing a little research on Dayton Audio's site about how to use and place the sound exciter speaker on to certain materials (wood, plastic, acrylic, etc), I felt confident enough to build a very neat 96 Watt speaker system. I was able to build two speakers, both made out of a 3/16" thick piece of clear acrylic which I cut to around 15in x 27in - basically a classic rectangle in shape. Each speaker has 2 exciters running together in series which increased the Watts to 48W each speaker & the 4 Ohms of each exciter (in series) to a total of 8 Ohms for both speakers. For the amp i used a WINGONEER TDA7492 Wireless Bluetooth 4.0 2x50W 2-channel Audio Receiver Stereo Digital Power Amplifier Board Module. Overall, I'm happy with my first speaker build using this product and plan to replicate the build with higher wattage exciters for my next build! Thank You, Dayton Audio!!UPDATE 2/4/21:Upgraded the original amp and power supply with what's listed below...DAMGOO Bluetooth 50W+50W Stereo Audio Amplifier Board with Treble and Bass Control, Bluetooth and AUX Inputs, BT 5.0 AMP Board for DIY Wireless Speakers Board, Easy Installation and Password Free by JUNTENG Co.,LtdLearn more: https://amzn.to/3a5CVHm24V 6A Power Adapter AC 100-220V to DC 144W Power Supply: https://amzn.to/2Z4XrBW

Sturdy

Clarity, crisp, en fun

I bought a pair of these after watching some YouTube videos. I was skeptical at best, having seen similar devices at dollar stores and gadget shops for a few years.As soon as they arrived I started placing them on every surface in my house, with sometimes impressive, sometimes disappointing results.Windows worked fine, drywall was meh, tables had mixed results....a large cardboard box was surprisingly good.Ultimately I decided to follow the suggestions of the many YouTube guides and got some project panels from the hardware store, and installed the exciters following the 2/5, 3/5ths placement.I was blown away. Not only were they clear and loud, they produced loud, crisp sound in the high and mid ranges. The low tones left something to be desired. Supposedly a bigger panel will address this, or maybe a more powerful amp/exciter combo.For the time being I'm super impressed. Will definitely be buying more and trying new configurations and surfaces.

Sounds very good.

Works great, perfect for what I needed.

I made 4 DML speakers from polystyrene. The sound is amazing and fills the entire room. My wife who is not as much of a music listener as I am has spent hours just listening to the music these produce. Such amazing sound at such a low price.Great little project.

I ordered TWO of these Dayton audio exciters for a speaker project I had in mind. Imagine my disappointment when I opened the boxes to find that ONE was empty!? I've heard of Quality Control issues before but this is a whole other level of Opps!The product itself works as you would imagine and you can make a unique flat panel speaker with very little effort. In my case i needed a center channel speaker for the bedroom and the thought of using a lightweight panel suspended from the ceiling was the perfect solution. Since my Sony AVR has a slightly higher output capability than a single transducer could be expected to handle smoothly I ordered TWO of them for installation on a single panel.At 25 watts these can't handle a lot of power on their own and if you push 'em just a little too much they'll go into overdrive and rattle like heck, hence my desire to use TWO of them. As a lifelong audio nut I'm kinda picky about the noise coming out of my stuff and even I'm impressed with what you can get out of ONE of these little toys. I admit I bought these as an experiment but the results were good enough that today I bought TWO of the 40 watt versions for the same project.I can see where these audio exciters would have applications as surrounds, left and right height speakers or Dolby Atmos type speakers because they're so adaptable and the panels so easily disguised as everyday objects. Would they ever replace the 12" and 15" drivers in my towers, or my Martin Logan electrostatics....not likely. But in certain circumstances these may just fit your application needs perfectly. My advice go for the bigger 40 watt versions if these are meant for larger areas and use the smaller ones for desktop or small rooms.The one thing to keep in mind is that you will experience the tonality of whatever surface you attach them to. The 1" foam panel gives the audio an odd plasticy sound, the acoustic ceiling tile deadens the output significantly and muddies the audio, the 3/16" birch plywood panel has the least detrimental effect of everything I've tried so far. I found that simply tapping the surface of whatever media you're considering with your finger nail is the easiest way to determine how it's going to affect the output.Also, that 3/5ths 2/5ths rule isn't necessarily applicable here when it comes to transmitting vocals as in my center channel application. It may be appropriate for generating pretty pictures of specific frequencies being played while watching salt crystals dance across the panel but the human voice is never that perfect or constant. I tried several different iterations of that formula including 1/5th 4/5th and finally settled on a dead center mount. This gave me the clearest focal point for vocals and eliminates that sort of breathless ethereal quality you get from the far end of the panel as the vibrations travel outward from the transducer.If nothing else you'll have fun experimenting, but don't expect too much and you won't be disappointed.PS. I'll give 'em more stars if they send me the missing unit.Update: I ran another test with just the center channel active and I'll amend my statement concerning the acoustic tile, it does indeed have the least effect on tonality of all three panels types I tried. As it turns out the breathless ethereal quality I described above comes from the reverberations emanating from the back of the panel and bouncing off the wall behind. Listening to these panels reminded me of a speaker outside of an enclosure playing in open air and that's exactly what's happening here.
