[QUOTE="desertheat, post: 2582767, member: 557169"] But looking into what tweets to go along with them... I ended up choosing the aurum cantus AC-180F1D.. they are a nice 7" dvc mid / midwoofer. And with an fs of 36hz midbass should be all I could ask for... and a responce that extends into the 6K range "looking to cross under 3K in an active setup" they babies should be pretty dynamic I hope... efifciency is not bad at 90dbm Good part is that my current auras are deeper than these haha, so depth is not an issue as well as mounting in my tC's doors are they have a nice large area... Any thoughts..? Here are the specs... Nominal power (P): 80W Sensitivity (SPL): 90dB Rated impedance (Z): 2¡Á8¦¸ Frequency range: 36 - 6000Hz Resonance frequency (Fo): 36Hz DC resistance (Re): 2¡Á6.8¦¸ Mechanical quality factor (Qms): 4.73 Electrical quality factor (Qes): 0.47 Total quality factor (Qts): 0.43 Equivalent volume of air (Vas): 60L Moving mass (Mms): 16g Effective piston area (S): 167cm2 Suspension compliance (Cms): 1.53mm/N BL product (BL): 4.53N/A Flux density (B): 1.13T Voice coil diameter (¦Õ): ¦Õ35mm Voice coil height (h): 17mm Voice coil inductance (Lbm): 2¡Á0.19mH Linear excursion (Xmax): ¡À6mm Magnet diameter (¦Õ): ¦Õ120mm Magnet height (h): 20mm Former material: Aluminum Weight of driver (M): 2200g Outer dimensions: 184¡Á184/¦Õ204mm Cutout dimensions: 169mm Frontplate thickness: 5.5mm Overall depth: 90mm [/QUOTE]
