The speaker plinth brings the speaker to a whole new level. Overall, the bass frequencies are greatly enhanced, with much better definition than before. Treble for some reason is also better, with a more relaxed sound that used to tend toward edgy and fatiguing.
Concrete and plywood floors cripple the sound of your speakers. They muddy the bass, smear the midrange, and add harshness to the treble. Many, if not most, perceived “room problems” are caused by bad-sounding floors.www.audiofurniture-
