How to choose the foam size: First measure the inner diameter of the bass reflex port tube.
If the inner diameter of the tube is 50mm, select 55mm foam; if it is 65mm, choose 70mm foam.
The foam should be slightly larger than the inner diameter of the port tube for a tight fit. This prevents the foam from falling out during high dynamic speaker playback.
Features:
1. Made of soft foam, provides effective damping to adjust bass reflex speaker sound performance.
2. Cylindrical design fits tightly inside speaker vent tube, prevents slipping out under high-volume playback.
3. Simple plug-and-play installation, ideal DIY accessory for tuning subwoofer and speaker cabinet acoustics.
4. Optimizes airflow inside the speaker box, reduces unwanted port noise and balances bass output.
5. Multiple diameter sizes available to match different inner bore sizes of bass reflex port tubes.
Note:
1. Not suitable for all speakers. If your speaker already delivers satisfying bass performance, we do not recommend installing the foam plug. Please purchase carefully!
2. The foam material is very soft. It is hard to apply even pressure during machine cutting, making it difficult to produce perfectly standard cylindrical shapes. Please consider carefully before ordering if you are sensitive about appearance.
3. When selecting foam size, compare it with the inner bore of the speaker port tube. The foam needs to be larger than the inner bore size to achieve a tight fit.
