Review: Allows you to retrofit backing boxes for in-wall speakers in a finished wall/ceiling! - This is an amazing product. I built a theatre in my basement about two years ago and decided to go with 5.1 sound at the time because there wasn't enough width to accommodate side surrounds on the walls and I wasn't thrilled with the idea of doing in-wall speakers on the side wall locations. I have since had a change of heart and decided to expand to Atmos surround with speakers in the ceiling. The good news was that I know every inch of what is behind the drywall in this theatre. The bad news is that I don't have the ability to do any soundproofing (in this case, building backing boxes) on new in-wall speakers without cutting out large sections of drywall to get access to the cavities. An installation of speakers in my ceiling would severely compromise the work I did to soundproof the room. I looked into every manner of solving this problem, starting with methods for designing and building my own solution, but nothing was even close to satisfactory. I finally bit the bullet and bought two of these. They are the only thing I found (product or custom made solution) that satisfied both of my needs: mitigate sound transmission through the ceiling, and install without unnecessarily tearing apart (and then repairing) my theatre. I was originally balking at the $100/each price tag, but now that I've installed them I've come to see that they were more than worth the money. The quality of these materials is top notch. That you can roll these materials up tightly and stuff them up through the speaker-sized hole in your ceiling is a revelation. Installation is incredibly straight-forward and easy. You simply cut a hole in the box to match your speaker (and a small slice for the speaker wire to feed through), roll the box up and shove it through the speaker hole, adjust the placement of the box until it's just right, shove the absorption panels through the hole and push them into place, and then seal the boxes to the drywall with a thick line of caulk. Designing and building out my theatre was incredibly complex, and figuring out and installing this product was one of the easiest things I ever did for it. This product introduces two of the four soundproofing methods: absorption and mass. Damping and decoupling methods would need to be satisfied in some other way, which matches my expectations when I bought these. I see other reviews here that say that this product doesn't do a great job in soundproofing, and that's just bull. The reality is that the single greatest method for soundproofing is decoupling. If your drywall is not decoupled from your studs and the studs of the room you are soundproofing are not decoupled from the adjacent rooms then your ability to soundproof the room has already been severely compromised; utilizing absorption and mass alone will not bear great results. This is not the fault of this product. What I can say on this topic is that this product performs as well as one could ever hope. It does a great job, but they are not magic. If your room is not decoupled from the adjacent rooms then you will hear sound from speakers in the adjacent rooms even if they are in these boxes. Obviously, you can't decouple a room once it has been built, so the best thing that you can do to soundproof when retrofitting speakers in walls or ceilings is to use these boxes AND install a thick layer of fiberglass insulation into the cavities above/behind them (and the entire cavity, if possible). If you want to learn more about soundproofing, I recommend starting with this article on The Soundproofing Company's website. Personally, I think that this product is amazing. I had high expectations and this more than satisfied them. My newly-installed speakers sound great, and the sound transmission into the adjacent rooms is just as quiet as it was before I installed the new speakers (I was actually expecting to lose some of the soundproofing once I installed the new speakers). If you will only be satisfied with a product that completely soundproofs your speakers then this product will not satisfy you. In fact, no product or custom solution will satisfy you because that level of soundproofing is impossible with just a single product or soundproofing method. Factor that in before dropping $100 per box on this product (really, factor that in before you decide to buy in-wall speakers in the first place).
Review: Get HEAVY DUTY SHEARS - I found this to be an excellent product. It is extremely tough and thick. The outer rubber itself is as tough and thick as an automobile tire. Lining it is some excellent acoustic pyramid style baffling. One of my speakers abutted a joist. Consequently I had to cut out the entire speaker width along the bottom face to one of the sides. Believe me cutting this stuff is really tough. I would be hesitant to use a utility knife. The hole comes with a circular dimension of I think 7 inches. So for each speaker I had to make a larger dimension for the hole. Again, I advise caution while cutting. This requires good sharp durable equipment unless you want to get injured When I had to do the off axis cut this removed a lot of the sound insulation. My solution was to buy some of the regular Dynamat surface stuff that you use in cars. I then cut this out and placed it directly on the attic side of the ceiling on the space that would not be covered by the sound baffle This works out better than it sounds. The speaker enclosure itself is quite pliable and will easily form over any additional sound insulation that you apply to the side of the ceiling that is towards the attic I had listened to the speakers without the enclosure for almost a year. My impression of the sound after putting up the speaker enclosures was that it was more focused. Plus since the attic is the same for other rooms you could easily hear this in the other rooms. The type of insulation I have is sprayed on the inside of the roof and not fiberglass insulation distributed right on top of the ceiling itself. So any sound in the attic goes throughout the house and directly into each room. This was definitely a very good solution. The price is about the same as each speaker but it is what is required

## Questions & Answers

**Q: Can you squeeze the rubber box to fit through the speakers’ 8 inch opening without needing to enlarge the hole?**
A: Yes you can fit it in there. That is why I bought it. We already cut the holes and then we realized we created a noise problem upstairs. What you will do is roll the Dynamat length wise like a rubber mat. Then you fit it into the hole and when it is in the hole you let it unravel and it fills the speaker cavity. The key question is how big is the cavity behind your 8" hole? You might need to reposition the hole to work with your home.

**Q: How large of a speaker can the dynabox accommodate?**
A: I have used the following sizes with that enclosure. 5 1/4”, 6 1/2”, and 8”.

**Q: I would like to order more of these rubber in-ceiling speaker enclosures, when will/do you restock them?**
A: Thank you for your inquiry, please note we have plenty of these enclosures in stock, ready to ship.  Please do let us know if you have any further questions.

**Q: What is the internal cubic foot volume of the boxes?**
A: With the foam inside ... about 1 to 1.5 cubic feet.

### ⭐⭐⭐⭐ Not a silver bullet, but moderate sound insulation and audio improvement
*by P***Y on March 4, 2023*

I purchased 5 of the DynaBox for my family room in-ceiling speakers. I have 5.1 surround system with directional in-ceiling speakers and the room sits directly below the upstairs master bedroom. There were two objectives in using these: 1) reduce audio sound in the upstairs bedroom and hallway that was coming through the upstairs floor that sits above the speakers and 2) improve sound quality in the family room itself by providing better backing to the speakers. The boxes definitely helped in both cases, probably more with the insulation of sound to the upstairs than a noticeable improvement of audio in the family room. With regard to the sound insulation, I ran a couple of subjective tests by playing the same movie scene and music at two different volume levels both before and after installing the boxes. I put the Denon receiver at a volume of 45 and then at 65 while playing the opening scene from The Dark Knight and then some rock music. Both my wife and I went upstairs and listened. After installing the boxes I'd say there was about a 30-40% reduction in sound coming through the floor to the upstairs. I can now play movies and music at higher volumes downstairs later at night and not have to worry about waking someone up. There was also a slight improvement in sound quality in the family room. My summary would be that these definitely provide some improvement but are not a silver bullet and will not completely eliminate sound coming through the backs of speakers to adjacent rooms/areas. They are also a bit expensive for what they do. Final thought, installation matters! Try to leave nothing more than minimal gaps and make sure the rubber part is flush with the drywall or whatever it is sitting against, and position that foam piece evenly in the back of the box to cover as much of the box as possible.
