If you are an audiophile, music enthusiast or musician, you will appreciate this. Our 12tooth Acoustic Foam is a great tool to improve vocal clarity and acoustics of your recording studios and home theatres, which will effectively flutter echoes and reduce excess reflection and reverberation. It is also an effective way to soundproof your rooms from unwanted or intrusive environmental noise. With its high density acoustic foam cell structure comprising 25kg/m3 properties, our foams are heavier and thicker than other ordinary acoustic foams for unrivalled noise absorption. The foam comes in a 30cm square with a 5cm thickness and our 20piece set will cover an area of 1.8m2 easily. Installation is quick by using staples, nails, screws or glue to put them up. Ordering earlier than these dates may help reduce the risk of delays during peak periods. Please do not return or post items before obtaining instructions from us first. If you do, there is a risk that your returned item may not be identifiable and accepted.
