Foam vs Rubber

The following review is for XBAF65, which is a part of the bundle you are viewing.

The best thing about these speaker baffles are the fact that they are rubber vs the easy to find foam. They definitely add a nice level of water resistance with the rubber. Not to mention the sound quality improvement. It's seriously a night and day difference. Trust me, just buy them!

Protect Your Purchase

The following review is for XBAF65, which is a part of the bundle you are viewing.

I like these baffle rings because it gives that added protection for my mid-bass component from any water that may slip through the window sill. It also helps with reducing any unwanted vibration noise. The egg crate foam placed behind the speaker on the inner lining of the door helps absorb waves to add more decrease in vibration.
The silicone-rubber material is going to last a long time and can be easily trimmed for a custom fit.

Don't go without it

The following review is for SDBSK2, which is a part of the bundle you are viewing.

This really helps with overall sound quality, especially mid-bass in my experience. NVX offers excellent quality at better prices are than other popular sound deadening brands.

The best speaker baffles!

The following review is for XBAF65, which is a part of the bundle you are viewing.

Love these baffles! The rubber makes it easy to mount, you could trim them but it wasn't necessary in my case. Love the little foam circle that goes with it! Improves your sound quality for sure! After I installed these baffles, all of the sounds are being directed back into the cab, its definitely louder now and adds a little more midbass.

The following review is for XBAF65, which is a part of the bundle you are viewing.

they work well. just make sure your on the spot before you stick the foam on because it is sticky.

Work great.

The following review is for XBAF65, which is a part of the bundle you are viewing.

At the very least these create a really nice seal. The ends do fold so it will clear the door panel.
