I bought a few different transducers to try on various surfaces throughout my house to see if I could come up with a sleek/invisible sound solution vs simply cutting holes in my ceiling and adding conventional speakers. I tried this product on 3/4" birch, 3/4" MDF and 3/4" sheetrock and ran it through its paces. It just doesn't provide a pleasant sound. I wanted to take some official response measurements, but could not find the time. However, I will say this the upper frequencies suffer tremendously given the nature of transducer designes in general. Also, for this particular product, you have to actually screw the transducer down using a center screw in the middle of the transducer itself. If someone was to waste their money on this product, be sure that you use a screw anchor if screwing this to sheetrock. It's an impressively heavy puck, that's about the only thing I was impressed with. I haven't taken the time to send it back to Amazon because I don't feel it was a complete waste of money. I plan on retesting with an external amplifier to see if 500watts will improve performance in any regard. Completely unscientific test... just want to see what kind of max output can be obtained from this product. Overall, I would not recommend this or any other transducer to anyone over even the cheapest in ceiling/wall speaker.

Not enough power and breaks easily.
For a normal sized deck (10' x 15'), you'd need at least 4 and an amp at full volume to listen at a casual level. For indoor in wall purposes it is probably fine, but for decks, it is just not powerful enough. Also, it is all about positioning to get maximum volume, however after 3-4 repositions, the screw with twist right off and that is with pre-drilling. So avoid these for decks.

I connected this to the sub-woofer output of the amplifier in the Shark Shkbra215-black 300 Watt 100% Marine Waterproof Amp / Speakers Bluetooth Sd Aux Fm w/ Lighted Speakers Black with Lcd Remote (available also on Amazon). I screwed it into the large plastic base for the boat driver's seat (a podium about 4 feet wide by 1 foot tall by 1 foot deep and made out of almost 1/4" thick polyethylene plastic) and used just a dab of clear RTV around the screw to keep it from coming loose. Works great to fill out the bass notes, really helps out the small speakers that come with the Shark stereo set. As a plus, I can "feel" the bass in the seat of my pants, as well as hear it by means of the seat podium acting like a speaker. RECOMMENDED!
