Review on 🔇 Dynamat 11102 Dynaliner 32x54x1/4 Thick Self-Adhesive Sound Deadener - Superior Noise Reduction Solution by Doug Hook

damper (from Second Skin) + Dynaliner is a great combination. The Dynamat is much more difficult to install than the Damplifier, but the second skin version of the closed cell foam liner is not self-adhesive. The steamer/Dyanaliner combo, while not cheap, is the best do-it-yourself installation. Don't be lazy, especially with doors, and simply use large individual sheets to cover the "middle" of the door. (This can often be seen in photos of "professional" installations.) While this requires a lot of small parts due to limited access, take the time to apply the damper to the door skin itself. 100% coverage isn't required, but I'll do whatever surface is available. Any material that is not firmly bonded to the metal surface is wasted. In my opinion it is also very important to deal with crash beams in the doors - they can act like tuning forks and contribute to noise and poor response from door speakers. While this costs 50% more material than you would expect in the open house area, it's worth it. The Dynaliner mounts on top of the shock and it's a lot easier because it's a lot more flexible. By transforming the doors into an almost real speaker box, the stereo sound quality is *significantly* improved, especially in the bass range and especially at medium to high volumes. This is probably the cheapest sound system upgrade on the market. Incidentally, with the doors open, I also spray a waterproof synthetic lubricant on the corner where the door skin meets the door frame. This corner is a great place to start roasting. Also, avoid covering this edge with sound deadening material - don't allow water to pool and, for the same reason, don't block drains underneath. The 1/4" version of the Dynaliner, once you have clearance to use it, seems noticeably more efficient than the 1/8" version. However, the 1/8" thick material is the best I've found to reduce annoying rattles that come from gaps between plastic trim pieces and where the plastic trim doesn't fit tightly to metal. Don't confuse this material with the typical open-cell foam that which is used for furniture cushions! It is not suitable as a sound absorbing or blocking material. Buy a genuine McCoy.
