... Delivered by the bluffs to the departure, I have bought for attnuer vibration on my furniture due to the speakers, and now I find myself with not only well but also an expected attnuation standard gain about rendering sound: deep bass and well Dfine gnral and much more sharp and clear. I have not been compared with Auralex, which are a tad more expensive (39 euros Thomann) but these are certainly excellent in every way and it will be difficult to do without dsormais.
