Yeah...so this is one of the greatest inventions of all time. I mounted it to my couch and it just brings a whole different dimension (literally) to my movie viewing experience. It's everything I had hoped for and then some. If I had any criticism, it's that this thing is almost too good at times. I'll be watching a video on some random thing, but the audio will be just low enough in the register to make the couch twitch. But honestly, that's really me searching for something negative to say. I love watching movies with this thing.

Have 4 in my theater room. LOVE THEM!!!! Never going back

It is a good unit, though I wish it went to a lower frequency.

Sick, brah! This thing delivers...

I'm giving 2 of these 250watts and they kick my racing rig hard if I choose to crank them up. Be forewarned once you have these you won't want to go without :)

Wow, this thing is AMAZING. I mounted it to the bottom of my desk chair and man, it sure does shake the chair. It adds a new level to your music or gaming experience. I played Forza 6: Apex with this and it adds a really cool feel to the game. I am definitely a tactile transducer believer now!

I bought these back in 2007. I have 8 leather recliners set up in my home theater room and installed 1 of these in each on the recliners. Then paired them up with a $20 receiver off craigslist. I hooked the craiglist receiver to my main receiver and now every time the subwoofer is triggered, all the seats in my movie room shake. 10 years ago these things cost $28 a piece and its not only the cheapest aspect of my setup, but also my favorite. The lobby scene of the Matrix and the D-Day scene of Private Ryan are my two demo clips for people that sit in them for the first time. I love these so much that I drastically reduced the amount of times I went to the movie theater as watching movies at home is better. Not sure if this is a true story, but I remember reading that when these first came out they were designed for sports cars that couldn't fit subwoofers. So these would give that same feel. They never really sold, and someone tried using them for home theater and the price of them increased quite a bit over the years. Even at its current price they are well worth the cost and all 8 of mine are still working after 10 years.

Ok, for all the people calling these subwoofers....you're wrong. They are not subwoofers...they are shakers. They simulate bass resonance with vibration rather than sound. These work awesome, I have a pair I bought elsewhere but they are the exact same product. when installing make sure you mount them to the frame of the couch so that the vibration travels all through the couch or chair. I had to add 2 boards to mine to connect the front and rear couch boards together and it made all the difference in the world.

Screwed 2 of these to the bottom of my couch. I hooked everything up and turned on transformers. WOW! these are awesome. Will buy again for sure.

Perfect !!! Thanks
