2x Universal Foam Loud Speaker Port Bungs 55mm Diameter x 40mm Height

Speaker Bungs are cylinders made from high quality open cell type foam. Simply insert them into your rear speaker ports.

Speaker Bungs can be used to tune your speakers to the room by changing the frequency response. Results will vary depending on the speakers and where they are located, but generally, our Speaker Bungs will reduce bass boominess, and are most effective when speakers have to be situated close to the wall.  

Size can vary by 1-2mm, so we recommend choosing a size a few mm larger than the diameter of your speaker port hole. A larger bung can be made to fit, but a smaller bung will just pop out, so if in doubt, go for the larger size, or please message us with measurements and we will advise.
