Ciò ha cambiato totalmente il suono dei miei altoparlanti. Non ho più vibrazioni.

انصح فيها

Installed these as part of an overall upgrade to my TJ 99 sound bar, worked well to reduce the vibrations in the sound bar and provide more depth to the sound and improve the overall sound

Excelente ayuda a la bocina a estar protegida y ademas le mejora la calidad y nitidez. No es para quien tiene activo l bocina con bajo ya que al no poder respidar no tiene bajo pero si tienes un sistema completo de audio con un subwoofer veras la mejora inmediata que le da a tus bocinas!! Recomendable ampliamente!!!

I recently put these in the driver/passenger side doors of my 2000 subaru rs sedan with 6.5 in Polk dxi650 speakers. My main reason for getting these was because when I installed my door speakers it was snowing out and I noticed water dripping directly onto the speakers. So, I rigged a thick plastic sheet into the speaker hole on both sides, placing the speaker and wires in the created cavity and leaving enough plastic on the edges so when I bolted the bracket back on it would create a seal so no water could get in. This did work but, my speakers couldnt breath. Now these arent very bass heavy speakers but making it so NO air could flow from behind the speaker made the plastic bag cave I made for the wires/speakers breath inward and rattle like crazy causing a super annoying sound on top of my already rattling door panels. So I needed a fix and thats what these baffles are for. I did have to modify my original brackets though. The brackets come with a sort of half cone protruding from behind creating a half cavity, for depth and to protect the speaker (but this still failed with rain water depending on how your speaker actually fit in the brackets with its terminals). I cut off the half sphere lumps to create a smooth flat bracket, inserted the new foam cave (so it goes foam brackets from speakers->plastic bracket screw into door panel->baffle->speaker) and positioned the speaker so the terminals are on the bottom. Cut out an area I felt wouldnt allow water but air could get in, and mounted. This did meet my requirements for water proofing, rattle reducing and plastic eliminating but there are drawbacks after experiencing the setup for a few weeks. First, while the bass is reduced this makes the rear speaker bass seem much more potentb thus throwing off the entire balance of rear/front. Some music is ok and there isnt much difference but a lot of times Id say my front speakers sound 60% the volume of my rears (adding +1 to my front with the front/rear balance of the head unit causes such a great difference in power output it makes the rears sound invisible). The baffles will also redirect the sound output to directly forward. To alleviate this cut more foam off the back of the baffle. I couldnt because of the rain issue which in this case causes the music to shoot at my feet instead of giving the "atmospheric" effect. Its not nearly as bad if you drive alone but when someone is in my passenger seat I can barely hear the front speakers unless the song is heavy on treble. All in all a good product for what I needed without fixing my window seals, buying dynomat and spending tons more money. My fix for the difference in sound dynamics was to buy an app called TuneShell for my iPod touch so I could better tune the music equalizer and take away the bass more subtly and raise the treble than what my head unit allowed. If your car has leaky windows, if you need to direct the sound output directly forward, cut out bass for an amp, etc, buy these. They are cheap and will hold you over until you can plan accordingly.
