Simple materials for the Ceramic Subwoofer by Joey Roth: Stainless steel, porcelain, and Baltic birch plywood, while aside from the electronic components, plastic is completely avoided in the system’s construction.
The subwoofer extends your system’s frequency response down to 40 Hz. While you will physically feel bass-heavy music, you’ll also notice new richness in vocals and acoustic instruments. The sound is neither boomy nor aggressive, but a balanced completion of the Ceramic Speakers.
The subwoofer’s amp connects directly to the Ceramic Speakers’ small amp with a single included cable, taking on the low frequencies that they would normally have to play. This allows the smaller speakers to focus on midrange and high frequencies, improving the clarity of the sound.
