George Z. ★★★★★ Oct 22, 2026

Fits the MP 300 perfectly, the die-cast aluminium feels really solid compared to plastic grilles I've used before. The finish matches the sub's look and it doesn't rattle at all even during heavy bass.

Alexander ★★★★★ Oct 21, 2026

Installed this on my MP 300 and it snapped right into place - no wobble or rattling even at high volume. The open design lets the bass breathe while still protecting the cone from accidental bumps. Really finishes off the look.

Carter M. ★★★★★ Oct 19, 2026

The grille fits my MP 300 perfectly and the open design doesn't block any sound from the sub. The aluminum construction feels sturdy enough to handle daily use without rattling.
