A question on our beloved foam baffles,lol.....when i secure these on my speakers......i use chalking strips to seal these bad boys to the speaker.....and then i cut a pin size hole to run the wires through and chalk that.....i'm just curious if you had a better technique to secure/seal the foam baffle to the speaker....i'm thinking of using fiberglass resisn and fiberglass matting....

you really should poke port holes into the baffle. But if you have it because of water issues then thats a good choice, i would also fibre glass it.....but when you go that far you may as whell give it like .5 cube's, and throw some sound deadinning in there.

I am curious, what speakers are they and where. why are you using the "foam baffles"?remember that most ( not all) car speakers are designed to run esentialy free air. As long as the wave comming off of the back of the speaker does not meet the front wave you are good to go. also the extent of any cancellation that might occur depends on how low the speakers are being cross over at if at all. as wave lengths get longer ie. frequencies get lower the need for better baffling increases. If you completely seal the back side of the speaker you can also limit the frequency response as a sealed enclosure has a natural roll off of 6db per octave. the plus side is that your pwer handling does go up. you can download a program like blaubox and input the theil samll parameters to see the effect on frequency on the enclosure size. sound deaden your doors and baffle from the front and you will probaly get the best results. but it all depends on the speakers.

Sounds like you have done all you can do. Sealing it and plugging the hole is about all you can do. You will lose some frequency response but increase your handling capabilities. You will also lengthen the life of your speakers if they are in the trunk. The baffle will keep the back pressure of closing the trunk from damaging your speakers.

yea i've been foam baffling on all my installs just for a more tighter sound and an insurance on my speakers, the vehicle's environment is not place for my speakers.....especialy in Boston,MA with the snow,salt, and bumps.....in my 86 300z i have mb quarts Q series all around.....and in my 88 mustang i have audionbahns all around (2 AS68Q 5x7 for the backs and 3.5 " AS31Q)

Foam baffles are a great way to protect the speakes when used in a trunk that has subwoofers, the shock wave of the subs will cause the smaller speakers cone to move, thus causing distortion. The foam baffle keeps the shock wave of the subs from interfering with the motion of the smaller driver.

For us in Canada, any auto parts store, stereo shop etc. Where u are, probably the same type of stores, they are about $20.00 pr canadian here. ------------- Top Secret, I can tell you but then my wife will kill me.
