Build The Foundation For Great Sound
Speaker Baffles, the Answer to Poor Midbass
Firstly the silicone back shield provides a weather proof cover for the speaker which directs water around and away from the speaker basket.
Secondly the front of the baffle is designed to meet up to the door card, sealing against it. This stops energy from being lost up in the door cavity so all the energy fired from the speaker is directed through the speaker grill of the door card and into the cabin.
Third is the egg-shell style back wave absorption panel which adheres to the door behind the speaker and stops the rear wave reflecting back into the speaker and cancelling and affecting the output of the speakers.
Removing all these common problems by adding speaker baffles with your speaker installation drastically improves the output and overall sound quality of every aftermarket speaker upgrade gives you more midbass response and clearer sound that more accurately represents what the original artist intended.
CLD Panels, Basic Noise Damping For Every Build
The primary way that CLD achieves this is through shear forces in the butyl layer caused by being constrained between the panel and the constraining layer while the panel is vibrating (flexing). When the panel flexes, so does the CLD. When the viscoelastic layer stretches and deforms, it naturally resists and wants to “snap” back into place.

Mass Loaded Vinyl - The Ultimate Listening Environment
Blocking is going to be the most effective way for a car since blocking only needs mass with an air gap, while absorption needs a relatively thick open cell or fibrous material. You would need an absorbing material that is way too thick relative to the size of the car to do anything meaningful for road noise. That said, those types of products still have their place, but let’s focus on blocking noise right now. In order to block noise you need to have a decoupled mass.
The most popular choice for this in the aftermarket car audio world is Mass Loaded Vinyl, aka MLV. To be effective you need 100% coverage. No way around it and I’ll give you an example as to why. Have you ever had your neighbor start his lawnmower up early in the morning after a hot night with your window open? Annoying right? Well it doesn’t matter how closed your window is, even all the way until there’s only half a centimeter left. Only once it is completely closed and locked into place is the sound blocked and reduced to an acceptable level. Same applies here. This material is applied to the doors, inside the roof lining, on the floor pan, boot area. Everywhere or nowhere!
All this to create the perfect listening environment.
It’s possible. With the right product and application your car will reject unwanted outside and structural born noise and keep the musical sound inside your car where it should be. At the same time the sound will remain unadulterated from the time it leaves the speaker to when it reaches your ears. Pure audio nirvana.
