\"Audioengine uses audiophile-quality, ferrofluid-cooled silk dome tweeters with neodymium magnets. Silk tweeters hold up well under high power and the edge-driven design gives a very smooth response. The woofers are aramid fiber woven glass composite with rubber surrounds. Aramid fibers are very strong, meaning the woofer retains its shape when being driven at high levels. The HDP6 woofers are housed in cast aluminum frames which provide high rigidity and increased heat dispersion.\" - Audioengine
