About the Hushmat Wave Breaker Kit

Do you have a noise problem?

You've finally got your vehicle's sound system dialed in so you're getting the sound you want…when the car is stationary. But when you're moving, road noise can force you to turn up the stereo to ear-blasting levels to compete. And when you turn your speakers up, the standing waves (or back waves) that build up behind the cones can introduce distortion. What can you do to combat this problem?

Verified employee purchase (What's this?)

They are easy to install, but I also don't notice a positive difference. I replaced speakers and included this with the upgrade. The system is much louder but bass doesn't seem as good as the old OEM speakers honestly. I also added sound deadening lining to the doors and don't notice much difference there either. Seems like I may have wasted my money and time doing all the install work.

Used the hushmat in a 90 VW Vanagon door which is pretty much a flat sheet of steel. Had a lot of vibration- distortion before but the hushmat toned it down and now the music can be heard clearly at higher volumes. Adhesive backing was easy to apply and overall am pleased with the outcome.

Pros: -Easy to apply -reduced distortion = clear sound

Cons: -none

1st time buyer, now lifetime customer!

Bradmiester from Montgomery, TX on 9/14/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Preface: I used copious equal amounts of noico sound deadening in all 4 doors in my RAV4 and I'm using Jbl club components in front and Jbl club coaxial a in rear. However, I have hushmat in the front doors only. Front sound is much more clear and loud, and bass is substantial compared to rear speakers, even when I sat in the back seat to review my install. Since the speakers are of the same manufacturer, same size, same woofer and same tweeter and same product line then my best guess is the better quality sound is primarily due to the hushmat. I highly recommend it! I'd never go without hush mat for the front stage again.

Pros: Improved clarity for all woofer frequencies and significant bass

Cons: None

This didn't seem as nice as the RetroSound deadening material I got, and I think it is more expensive. Not really impressed, especially for the price.

Pros: I used it

Cons: Expensive for that it is and how much you get

Combine with the baffle, and you can barely hear music on the outside of. My f150. Which means the sound waves are contained in the truck.

Used this in conjunction with sound deadening on a 77 F150 and it was worth every penny! Would recommend to anyone looking for the most out of an older vehicle. Never tried it in a newer vehicle, but I can't imagine that it would hurt anything.

Wave Breaker Indeed!

Anthony L from Portland, OR on 9/19/2016

Verified customer (What's this?)
Verified employee purchase (What's this?)

During the course of product research and installation of a factory replacement receiver and a pair of speakers in my 1992 Ford F150 I came across the Hushmat product. After reading the description and its purpose (and since the doors of the truck are essentially just hollow metal panels) it only made sense to use Hushmat Wave Breaker to prevent distortion. One mat each mounted directly behind each speaker on the inside of the door using via the peel and stick backing and that was that. In a before and after test it was quite evident that the Hushmat Wave Breaker did exactly what it was supposed to. Even before sealing all the openings in the doors with a sound deadening barrier it was clear that Hushmat Wave Breaker nullified any wave distortion!

Pros: Easy, inexpensive and it works. What more need be said?

Cons: None

The product was easy to apply and the speaker sounded clearer with tighter bass after installing the hush mat wave breaker. I am using them behind a pair of 6 3/4 inch coaxial speaker in the rear doors of my Silverado.

Pros: Easy to install. Effective at improving the sound and performance of the speakers.

Cons: None.

Product Research

Features

HushMat Wave Breaker: Wave breaker is pressure-sensitive, semi-closed large cellular, synthetic rubber foam, which has excellent adhesion properties. The Wave Breaker structure is designed to efficiently disrupt sound waves into a random surface thus allowing the full sound quality of the speaker to perform without distortion. Wave Breaker is also a very light weight substrate and will bond directly to the HushMat Ultra on door speaker applications or the back of sub woofer enclosures.

  • Wave Breaker effectively disrupts back wave from speakers in a wide frequency spectrum from 10 to 15000 Hz.
  • Reduces road noise & vibration; low frequency noise from 0 to 1,000 Hz.
  • Reduces thermal transfer by over 40%.
  • Insulates from -30° up to 550° degrees Fahrenheit.

How Wave Breaker Works: When the speaker cone moves in and out waves are created in two directions. The wave that moves out the front is called music. The wave that moves out the back of the speaker is called distortion. This back wave reflects off the solid surface behind the speaker and bounces back to the front essentially throwing the speaker out of phase. When HushMat is placed behind the speaker these back waves are absorbed and broken up in the wave breaker molecular structure. This prevents the bounce back and therefore prevents the distortion. Therefore you get all the music out of that speaker

Temperature & Environment Resistant: HushMat Wave Breaker is temperature & environment resistant and will maintain adhesion through all automotive environments from -30° to 300° F). Humidity, UV and other conditions consistent with automotive use will not disrupt Wave Breaker performance.

Simple To Install: The HushMat Wave Breaker cuts with scissors and features a self-adhesive backing for peel-and-stick installation. The superior adhesive properties of Wave Breaker allow it to be used in horizontal, vertical or inverted applications. It has good conformability and can be applied on complex shapes. It bonds to fiberglass, plastic, and all metal surfaces. Use one Wave Breaker per coaxial speaker, or two Wave Breakers per sub woofer.

The Hushmat wavebreaker goes on the rear wall directly behind the magnet of the speaker. I used these on a pair of rear 6 3/4 coaxials in my truck. I placed the wave breaker on the inside of the door skins behind the speaker. Hope this helps.
[ STEVEN  Mar 08, 2016 ]
A
From my understanding it goes behind speakers of all kinds to stop Soundwaves from bouncing off the surface behind the speaker and crazing back into the speaker, which will cause distortion. I can't answer exactly but I hope it helps a little.
