Dynamat 13105 DynaPlate Aluminium SPL Panel Damping 3 Sheets

Dynamat 13105 DynaPlate Aluminium SPL Damping Material Three 609mm x 762mm Sheets Structurally Reinforces Body Panels Prevents Ballooning 50 Percent Better Damping Than Dynamat Original

The Dynamat 13105 DynaPlate is a two-layer aluminium SPL damping material that structurally reinforces vehicle body panels. Three sheets at 609mm x 762mm (24" x 30"). Damps 50% better than Dynamat Original. Prevents the panel ballooning effect common in doors, floors, and subwoofer enclosure faces.

Product overview

DynaPlate is a structural reinforcing damping material for applications where standard butyl rubber CLD is not enough. The two-layer construction creates a non-flexible panel composite when applied to sheet metal, preventing the ballooning or flexing that occurs in doors, floors, roof panels, and subwoofer enclosure faces under acoustic pressure. By eliminating panel flex, DynaPlate reduces vibration and removes one of the main sources of low-frequency distortion in car audio systems. DynaPlate damps 50% better than Dynamat Original and is suited for use on floors, roofs, doors, subwoofer enclosure faces, and any area requiring structural panel reinforcement in addition to noise damping.

Frequently asked questions

What is DynaPlate and how does it differ from Dynamat Xtreme?

DynaPlate is a two-layer aluminium structural damping material designed to reinforce and stiffen body panels. Dynamat Xtreme is a butyl rubber CLD that damps vibration without stiffening the panel. DynaPlate is used where the panel itself needs to be made non-flexible, such as subwoofer enclosure faces and door outers in high-output audio builds.

What is the panel ballooning effect?

Panel ballooning occurs when thin sheet metal flexes in and out under acoustic pressure from a subwoofer or loud audio system. This flex causes distortion and buzz, and in extreme cases can cause the panel to fatigue and crack. DynaPlate's two-layer construction makes the panel rigid enough to resist this movement.

Can DynaPlate be used on subwoofer enclosure faces?

Yes. DynaPlate is specifically suited to subwoofer enclosure faces where panel flex and resonance at high output levels can significantly reduce bass quality and enclosure integrity.

Is DynaPlate used instead of Dynamat Xtreme or alongside it?

DynaPlate is best used alongside Dynamat Xtreme. Dynamat Xtreme damps residual panel vibration while DynaPlate structurally reinforces the panel to prevent flexing. The two products address different aspects of the same problem.

What areas of the vehicle can DynaPlate be installed in?

DynaPlate is suited to floors, roofs, doors, subwoofer enclosure faces, and any area where structural panel reinforcement is required in addition to vibration damping.
