  • Product typeSpeaker Baffles

  • Creates tight acoustic seal behind speakers

Fit and Function

These foam baffles are made for 4" x 6" car speakers and ship as a pair. The light weight foam compresses to match the mounting surface and creates a tight acoustic seal behind each driver. They suit installers who want a cleaner mid‑bass response without modifying the door panel.

Sustained Performance

The waterproof foam resists moisture that can degrade paper cones over time. By damping panel vibration the baffles keep the speaker output consistent during extended play. The material can be trimmed to adjust the internal volume, letting the installer tune low‑frequency behaviour for the specific vehicle.

Build and Mounting

Each baffle has an inner dimension of 5.75" x 4" and a maximum mounting depth of 2.75". Overall size is 5.9" long, 4.1" wide and 2.6" deep. The foam cuts easily with a knife so it fits irregular openings while still sealing the rear wave.

Questions about this item

Will the foam baffles trap heat and degrade after long daily drives?

The lightweight foam is waterproof and compresses to seal behind the speaker without retaining heat, so it remains stable during extended use.

Do I need 4" x 6" speakers already installed to use these IBBAF46 baffles?

Yes, the baffles are sized for 4" x 6" speakers with a 5.75" x 4" inner dimension and 2.75" maximum mounting depth.

Will these fit behind factory door panels on an older vehicle?

At 105 mm wide, 150 mm long and 67 mm deep they compress to fit most speaker cavities and can be trimmed for tighter clearances.
