Ultimately, we chose wool pulp for its ability to deliver astonishing realism and detailed timbre across the harmonics. We then added an acoustically-transparent chemical to help the soft parts resist moisture.<\/p>\n<p>Our speakers will pull you into the musical performance and breath new life into your music
