 STOP SOUND INTERFERENC 

– Installs directly on the front of your speaker between the cone and the door panel. Creates an airtight seal that eliminates sound wave cancellation, unwanted resonance, and muddy bass. Your music stays clear, not lost inside your doors.

 DUAL V-GROOVE FLEX DESIGN

 – Unlike generic flat foam rings, our VRK series features two different groove sizes (10mm & 15mm) on each side. The wave ring bends smoothly around speakers — giving you a perfect seal every time.

 CLOSED-CELL FOAM WITH HIGH-STRENGTH ADHESIVE 

– 1” thick foam provides maximum isolation with zero air leaks. The aggressive adhesive bonds securely to any speaker surface and stays in place even in hot or humid car environments.

 UNIVERSAL FIT FOR ANY SPEAKER SHAPE 

– Covers any size speakers, or round, oval (6x9), square speakers. Each 27” strip is fully customizable — simply cut to the exact length you need. VRK-Q (4 strips) covers 4 speakers or a full front+rear setup.

 SIMPLE FRONT-MOUNT INSTALLATION 

– Just cut, peel, stick onto the front of your speaker, and reinstall your door panel or grille. No special tools, no drilling, no permanent changes to your car. A quick 10-minute upgrade for crisper, cleaner sound on every drive.

 COMPLETE KIT INCLUDES BACKWAVE BLOCKING PADS 

– Each VRK kit comes with acoustic egg foam pads (5”x7”) to tame reflections behind your speakers — addressing distortion from both the front and the back.
