[QUOTE="Electrodynamic, post: 6688739, member: 548723"] The latter specifications were taken directly from the Sundown Audio web site here, [URL="http://www.sundownaudio.com/index.php/products/subwoofers/nightshade-15.html"]Sundown Audio - Nightshade 15"[/URL]. The BL is specified as 22.8, Re is 2.92 for the dual D2, which leads BL^2/Re to be 178. Sd is taken directly from Jacob at Sundown. How are those figures wrong? The parameters are with the coils in series, which is the industry standard. We are talking about a Sundown Nightshade v1 aren't we? I assume so, since the v2's aren't out yet. [/QUOTE]
