Product Details

Dayton Audio HDN-8 Weatherproof Sound Exciter Transducer

Unlike a tactile transducer that delivers 'shake' effects to your listening experience, the HDN-8 Sound Exciter Transducer is a full range, versatile, compact transducer that can excite a surface or structure over a wide bandwidth, enabling the creation of completely hidden audio systems in walls, ceilings, and floors. Its high power handling allows it to produce useful sound levels with a small number of transducers, and its hermetically-sealed design permits indoor or outdoor installation, even in wet or humid environments such as outside decking or an inside bath/shower installations. It features a single, coarse-threaded mounting stud that easily installs into wood, fiberglass, or plastic, and the 8-ohm impedance allows integration with conventional audio amplifiers.

Specifications: • Frequency response: 40–15,000 (typical) • Sensitivity: varies by application • Dimensions: 4" W x 1.75" H • Impedance: 8 ohms • Power handling: 50 watts RMS / 100 watts maximum.

Frequency response is dependent upon the resonant nature of the material the HDN-8 is mounted to, as well as the type of environment and mounting configuration selected.

Additional information: The HDN-8 is a transducer that produces sound through resonating surface area. The surface area and material act as a carrier for the sound energy. Because the sound is through resonation rather than vibration, the surface material will move no more than .01 inch. This is less than most surfaces contracting naturally from humidity and changes in the weather. If mounted behind drywall there will be no damage to the drywall joints or drywall screws. Because the HDN-8 is not designed using a cone or surround, there are no parts that are susceptible to damage. Every HDN-8 is fully tested at the factory to perform to manufactured specifications.

Dayton Audio HDN-8 Weatherproof Sound Exciter Transducer
Dayton Audio HDN-8 Weatherproof Sound Exciter Transducer is rated 4.0 out of 5 by 11.
Rated 2 out of 5 by from Put out sound but, definitely not high fidelity...Bought these recently to try and get reasonable surround sound effects using existingdrywall in a room as the soundboard. Used a 1/4 in. inside wall wood panel for support as the instructions indicated. Wished they (Dayton Audio) had made the attachment bolt (screw) a little larger for better stability. Practically no treble and what midrange and bass there was sounded muddy and lifeless. Voices and other low mid to middle frequencies were okay but, what I wanted was more of a dynamic sound. Drywall sheetrock in of itself, is not dense enough for a vibrational medium for reproduction of audio frequencies. Have a recipe for making the drywall much more dense, so will try that soon.Maybe would sound better fastened to more solid materials such as other installs like wood decking, panel or beam supports and such.If anybody has some suggestions, it would be appreciated.

Rated 5 out of 5 by from Great sound ot of something fairly inexpensive.I bought them being skeptical on how they would be for quality. A good amount of quality issues can just be from what type of material that is being used for the sound. Floor joists in a home give a nice rich felling throughout the house when they are spaced out enough, plywood can be OK but depends on type and construction. Use a tight grain wood like oak or walnut. Pine floor joist or deck joist give nice sound also. I am using four at my parents lake house and they like them a lot. My boss likes them also an was wanting me to maybe install some on his boat be low deck to be able to have sound travel through the hull into the water.I did have issues with one but Parts Express had it fixed for me quickly.

Rated 4 out of 5 by from Very Interesting...I purchased these just to try-out. I was going to add them to the existing speaker set-up on my deck, but haven't gotten around to it yet. I DID try them out with various materials to see how they performed. Mounted to a small sheet of 1/4" x 12" x 20" wood paneling they sounded quite good, lacking a bit in the high-range, but that's to be expected. Mounted to a 2 x 4, no good at all, too dense I suppose. Mounted to low density foam, no good either. Mounted to a 2-foot oak log, okay but not great, I did this as a joke, thought it would be cool to have a set of "log-speakers" in my living room! I think if you find a good medium, they will sound great, but you'll have to experiment to see what works and what doesn't. All in all a nice quality item, seems well made and at a great price!

Rated 5 out of 5 by from Better than my Bose.Screwed two pucks to the ceiling of my deck (1/4 plywood) Powered by Lepai LP 2020A 20 watts RMS. Ran the wire 14 gauge up through the ceiling. The sound is incredible. Have not gone to full volume yet as I do not need to. Outside with a waterfall, traffic etc can hear the music clear as a bell. I first tried a battery powered Dayton DTA-1 and got some distortion at high volume. Just not enough power. I may upgrade from the Lepai to a larger Amp 50 watt.Super easy installation, drill small hole and screw the puck in. The connections are great especially since it is a very tight space to plug them in.

Rated 5 out of 5 by from Dayton Audio HDN-8 Weatherproof Sound Exciter usesI got 6 of these and am testing them. They are about 3lbs plus of magnet structure in a tough plastic sealed puck, you would not use them underwater or in direct rain, but they would be damp proof in a semi protected area out of the rain outdoors. The frequency range as rated at 40-12 is accurate as to my first test, on a large slab of blue foam about 3'x4' that is epoxied to door skin with the puck mounted on a hard wood flat about 6"x8" bolted to a central location on the foam side. I used them in a small boat, facing each other on the inside side panels of an open top cuddy cabin, boat is 4x16 ft, cabin is 3'x4' for some dry storage under a Bimini, each side panel is the hull cabin panel, ie a speaker inside and out. It would irritate the neighbors. It might call gators if you played their song at night. They sound muddy on my plywood shop wall. They are very power hungry and use up most of a 15 watt Lepai amp. Not efficient but heavy hitters. I would expect the same on a 1/8 acrylic panel or foam core if the puck was screwed into a hard wood square, bolted on, or any material, as long as the hardwood is big enough to transfer the resonance to a larger area. A thin light wooden panel would be very good. Plywood is a mix, the glue structure of a heavier cross ply panel layup tends to dampen the sound. Door skin is light, foam is light. On the highs. I would expect a section of light aluminum on the outside of the panel bonded on but perhaps free floating on most of its surface would make for more highs, or a second smaller exciter on aluminum as a full range speaker. Small aluminum solar panels on the boat cabin outside seemed to resonate as well, and changed to sound a bit. I am trying to just use one puck per channel since I am trying to stay with the water resistant issues and the need to drive recorded sound into the natural environment as a part of a video project. I would think on a large panel with the highs addressed made very well its a nice DIY play. Sounds like an old 12 inch 3 way from the fifties with a dead tweeter, if the power comes from a 50 watt T amp it would be cleaner so you do not drive it to distortion levels. Its all about the panel structure and getting it to resonate like a guitar body. It could be as high tech or low tech as ones desire to play with the panel structure. The simple solution is to get a tweeter and mount it off panel. The sound reflects off the back and front of the panel, or a wall. Distance from the wall is important. The idea you put them inside a normal wall is not sane. Vibrating palmetto bugs, loose sheet rock screws. The use of them on a wall panel speaker outside the wall or a folding screen speaker is DIY fun. Or outdoor uses. I will make some for indoor use. Perhaps return with a review. A very good deal if you want to shake the bass out of an excited very dry zombie, or the material of choice. Just get the zombies to stand a certain distance apart and hum along with an old Pink Floyd song, or blues standard.

Hi-  What kind of "fast on" speaker wire connectors would you advise using with this product?

Asked by: bryon
This has 0.205" terminals.

Do these 'couple'?

so, traditional drivers 'couple' when arranged adjacently. to these devices do the same?
Asked by: madmallard
Yes. As long as they are wired + to + and - to - they will be in phase and increase in their effect. This technology was once used to drive subwoofer speakers.

Is the moving surface of the Sound Exciter Transducer just stud or back side as well?

If it is just the stud surface and mounted to the panel, does this mean that it is not supported on the back side free to move independently? Could it be mounted via back surface solid and mount a free moving panel to the stud end?Thanks for your time,Truck
Asked by: TRUCK
The frame or mass of the exciter is attached to the stud in order to efficiently transfer the vibrations so this can only be mounted by the stud.
