Replacement Woofer for 15" Realistic Mach One 8 Ohm

Details

Radio Shack produced the Realistic Mach One speaker for almost ten years, beginning in the 1970s. The Mach One 15" 3-way system is considered one of the finest loudspeakers offered by Radio Shack. Over time, many Mach Ones have been lost due to foam rot and old age. We've produced a 15" driver that features the same warm, thundering sound characteristics as the original, but thanks to contemporary materials and technology will last far longer. Now you can resurrect your set of Realistic Mach One speakers with completely new woofers, giving them a fresh lease on life! Specifications: *Power handling: 125 watts RMS/250 watts max *VCdia: 2-1/4" *Le: 1.82 mH *Impedance: 8 ohms *Re: 7.2 ohms *Frequency response: 22-1,200 Hz *Fs: 22 Hz *SPL: 90 dB 2.83V/1m *Vas: 12.09 cu. ft. *Qms: 4.94 *Qes: 0.63 *Qts: 0.56 *Xmax: 2.5 mm *Dimensions: A: 15-1/4", B: 13-3/4", C: 6-1/4".

Vifa NE123W-04 4" Full Range Woofer

Details

Vifa's NE Series full-range drivers feature an innovative sculpted, open cast aluminum basket design that minimizes internal acoustic reflections and acts as the neodymium motor's heatsink. An additional heatsink provides extra thermal dissipation. The cone is constructed of a coated natural wood fiber, with a butyl rubber surround designed by finite element analysis for linearity of performance. FEA techniques also contribute to the motor's copper cap, which reduces inductance and extends high frequency performance. Specifications: *Power handling: 35 watts RMS/100 watts max *VCdia: 1-1/4" *Le: 0.04 mH *Impedance: 4 ohms *Re: 3.3 ohms *Frequency range: 60-8,000 Hz *Fs: 66 Hz *SPL: 88.2 2.83V/1m *Vas: 0.13 cu. ft. *Qms: 6.7 *Qes: 0.44 *Qts: 0.41 *Xmax: 3 mm *Dimensions: Overall diameter 4.85", Cutout diameter 3.75", Depth 2.85".
