Pair of B3N 8Ohm 30Wt speakers.  Hi-Vi B3N 3" Round Full Range, Copper Color Cone Hi-Vi B3N 3" magnesium/aluminum alloy coper colored inverted dome full range. Shielded magnet, rubber surround, frequency range 80Hz to 8kHz. 90mm round flange, 53mm deep. 8 ohm, 81dB, fs 77Hz, Qts 0.86. A full frequency design Advanced alloy (magnesium/aluminum) cone, coated with special damping material, and anodized. Optimum recovery CONEX supporting system, having very good stiffness and dynamic stability, improving the sonic features of the speakers. High power handling, heat-resistant Kapton Voice coil former and heat-resistant CCAW voice coil wire Finite Element Analysis for shielded magnetic system with long-throw linear excursion design Hi-Vi Symmetric Motor Drive (SMD) technology makes the voice coil into a symmetrical driving magnetic field, thus acquiring symmetrical driving force, reducing the mutual modulation of voice coil inductance and back electromotive force, improving the controllability of the speakers, achieving low distortion degree Finite Element Analysis for flat & rigid iron frame, prevents the parasitic structural resonances Using leading technology of Small/Thiele parameters Suitable for midrange, surround speakers a in home theatre system, and also suitable for computer multimedia speakers Nominal Impedance (Z)(?) : 8 Resonance Frequency (Fs)(Hz) : 77 Nominal Power Handling (Pnom)(W) : 15 Sensitivity (2.83v/1m)(dB) : 81 Weight (M)(Kg) : 0.55 VC Diameter (mm) : 20 CCAW DC (Re)(?) : 6.5 VC Length (H)(mm) : 9 VC Former : Kapton VC Layers : 2 Magnet System : Shielded Ferrite Force Factor (BL)(N/A) : 3.1 Gap Height (He)(mm) : 3.0 Linear Excursion (Xmax)(mm) : 3.0 Suspension Compliance (Cms)(uM/N) : 1320 Mechanical Q (Qms) : 4.48 Electrical Q (Qes) : 1.07 Total Q (Qts) : 0.86 Moving Mass (Mms)(g) : 3.2 Effective Piston Area (Sd)(m2) : 0.0030 Equivalent Air Volume (Vas)(L) : 1.7 Cabinet Type : Sealed Recommended Box Volume(Vb)(L) : 2 -3dB Cut-Off Frequency(F3)(Hz) : 80
