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 is rated 4.0 out of 5 by 11.
Rated 5 out of 5 by from did just what I expectedworks like it should - nice and solid with good sound
Date published: 2014-10-17
Rated 4 out of 5 by from Haunted House BlissI place these inside the 4'x8' wall panels of my haunted house maze. They are perfect since the space inside the maze is in close quarters, so this allows me to keep the speakers hidden. If you have a bass heavy soundtrack, you will need to add a separate sub. People are always amazed at the sound in the haunt, because they can't tell where the sound is coming from. I have several panels that have these exciters preinstalled to make speaker panels. When I build the haunt, I add two of these panels to each side of each room and a small sub if needed.

Rated 2 out of 5 by from High expectations - low performanceI was hoping to have some decent (not high fidelity) – discrete speakers installed inside and outside at my home that is being renovated. I bought a few of these transducers and applied them to a variety of surfaces.As much as I tried – I could not get them to sound decent enough to use for background music. Also – these transducers are much more fragile than expected. One fell apart in pieces with a very small drop.Bottom line – I spent a lot of time trying to make it work – because I love the concept – but could not get enough tonality out of installations to use for background music.

Rated 4 out of 5 by from GoodScrewed these in to a chair, sound great and really enjoy the bass they put in to the chair. Only thing i notice is that i have to crank my jvc Super A to around half to get a descent amount of audio and by then the tower speakers are 3x louder. Prolly the wood of the chair its self but still sounds great. Perfect for a home audio or gaming chair.

Rated 4 out of 5 by from THEY WORK, BUT!I finally got around to mounting these units in mid-April(due to the extended midwest winter!). They actually sound pretty good. I mounted on the back of an outside bar. However , I am using them in conjunction with a set of high efficiency outdoor speakers mounted on the house eves. So, I can't balance them unless I add a couple of L-Pads, which cost almost as much as the Exciters. For low to moderate listening, they perform quite well.

Rated 4 out of 5 by from Mind the mounting locationI bought this to use as a low frequency driver in my old wooden boat. I also purchased a couple of cheap marine grade speakers for my left and right channels. I was planning to drive this transducer with the sub channel of a Lepai 2.1 and pipe in my Android phone as the source. I had a 1/2" thick drawer box that seemed like the right sort of sound board to test with. (My boat is an old lapstrake mahogany plywood boat with a half inch thick cabin bulkhead.)In testing the transducer, I found that my idea of driving the middle channel with the bass channel of the Lepai to be an abject failure. I couldn't get a decent sound out of the panel box. Before giving up all together, I chose to try the box on the left channel and compare it to my regular 5.25 speaker. Pretty impressive sound. Not much at the very top or below 100 Hz, but it had a nice resonance around 120Hz and impressive highs. I will be returning the Lepai and buying a real amplifier (over 20 watts RMS) to more fully power my 2.1 set-up.

I'm a bit of a noob, but I want to make a sound system in my office. I have a long hardwood desk attached to the wall. so I'm Looking at attaching 2 to the underside (about 2m apart) and then attced to my appe imac What will I need to complete this?

Would mounting these to the underside of a deck board produce a reasonable sound and volume paired with a 40 watt receiver?

Asked by: BDL Wayne pa
This really depends on the deck. Chances are this is not a great application for these unless you have a high number of them. They will probably cause some vibration at lower frequencies but they will not work the best for full range.

Given the pointed screw, how would i mount to a glass shower door? Do you have a glass mount available?

Asked by: rkellyp
Unfortunately we do not have any other mounting method available for this other than the wood screw mount.

Could this Dayton audio sound exciter be used in say a Polaris razor using a 12v system?

Asked by: Muffin
This can be powered with any standard amplifier whether it is on a 12v or 120v system. I would recommend a marine grade amplifier with at least 25 watts per channel at 8 ohms.

How would these compare to typical transducers as far as tuning is concerned? In other words, will using a bandpass filter allow greater output, or do the physical/power handling aspects of the driver make this a moot point?

Asked by: colin321
These drivers will have the same thermal and mechanical limits as any other transducer, so yes a high pass filter can be beneficial although the thermal limits of the driver will not be changed.

Is the wood screw removable? I know that it will eventually shake itself loose from the board I will attach it to and would like to bolt it on.

Asked by: dango
Unfortunately no it is not. This unit will not come loose with the proper sized pilot hole drilled in the structure for mounting.
