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

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!!

car hood and a door shell for speakers! good sound!

They work just fine.

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.

These things are awesome. I wired them in my pickup and just let the magnet stick to my cab body. Sounds a little tinny but these things will crank. I wish I had 50 of them throughout my house!

This project converts two cabinet doors into floating distributed-mode loudspeakers (DML) using 3 mm Dibond / Alupanel composite panels. Each door functions as a speaker panel, driven by a Dayton Audio DAEX25FHE-4 High-Efficiency 25 mm Exciter, and powered by a Douk Audio M1 PRO Bluetooth amplifier with an external powered subwoofer for bass support.

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.

Installed these on the back of some cheap paintings. They sound good and the tape holds good. Great for discreet audio. Definitely not much bass though.

It sounds great

I bought this little device with the intention of testing it on a home theatre couch, independently amplified with a lepy2020 and using my theatre amps' sub woofer outputs or phone 3.5mm out as signal. It is MUCH too small to work bolted to a couch frame, but I had a lot of fun hooking it up to ceiling tiles, walls, tables, my homes vents, pretty much anything rigid. The sound quality achieved by holding it against an MDF ceiling tile was better than expected, probably better than some low end soundbars, but in the end this was just a fun toy. I will be keeping it around for future tinkering projects (maybe hooking it up to a rigid computer chair as ive seen other users do for additional "rumble" effects). This would probably be a great little science lesson for kids.

まず、充電式のBTスピーカーは充電が面倒なので論外。 天井埋込の防水スピーカーを付けるのが正攻法だけど、壊れたときにどうするか問題がある。 そこで、音質は覚悟のうえでこちらを採用。 これを2個と、安物の20Wx2ch中華アンプを購入。 音源はエコードット。 アンプとエコーを浴室入り口の上に置き、アンプからの配線をユニットバスの天井裏に引き込んで繋いでこのスピーカーを置いただけ。 本来なら分厚い断熱材を切り抜いて天井材に直接、付属の両面テープで貼り付けた方がいいのでしょうが、加工前に試しに置いたら充分だったのでそれ以上の加工は中止。 曲は大量にあるし、全て音声操作。便利です。

j'en avais acheté 4 , pour 48 w par enceinte, donc par deux en série , le tout fixé sur une fine plaque bois (le meilleur résultat acoustique), et franchement je ne peux pas faire machine arrière, ces deux système en frontal de par et d'autre du grand écran, et deux autres enceintes classique type bibliothèque, et les deux graves de part e t d'autre derrière la canapé attaquées par mon vieux Denon , et les reste par des petits amplis class T, le son est précis , on redécouvre la musique et l'ambiance des films, ce n'est pas du 5.1 mais de la quadriphonie, et ça me convient parfaitement, le top (y)
