Part of PreSonus' Sceptre series, the PreSonus Sceptre S6 active coaxial monitors are bi-amplified with a full 180W of Class D power, along with a 32-bit dual-core processor, 6.5" woofer and 1" tweeter. Like the Eris series, the Sceptre S6 has acoustic shaping controls that allow you to be prepared to produce, mix, or listen in any and all environments. Thanks to all of this redesign and engineering, the Sceptre S6 gives you a wider, clearer soundstage with more impressive dynamics.
