Speaker manufacturers develop and design their speakers based on tests that are performed in anechoic chambers where the speakers are suspended in the middle of the room i.e. there is no interaction between the speaker cabinet and a hard surface. Once the speakers are implemented into real world applications, the speakers will not sound the same because they are now interacting with the environment. SpeakerDudes(HD) are isolators for your speakers. They will decouple your speakers from the surface they rest upon, resulting in a more pure, accurate tone. Low frequencies will be projected and will no longer lack the definition you desire. Mid and high frequencies will be crisp and intelligible. Rattles and resonances will be a thing of the past.
