[QUOTE="Greggk, post: 7468268, member: 606248"] ok so apparently there is 2 different types. the old school [IMG]http://www.woofersetc.com/images/Product/medium/4903.jpg[/IMG] and the new style [IMG]http://www.woofersetc.com/images/Product/medium/rex_reaudio.jpg[/IMG] on paper they look identical from what I can see, only difference being mounting depth. here is the old school style stats Mounting Depth - 4" Mounting Hole Diameter - 7.125" Overall Diameter - 8.25" Bolt Hole Circle - 7.75" Motor Width - 4.875" Motor Depth - 1.5" Basket Depth - 2.5" Displacement - 0.07 cu. ft. Electrical Q Value -Qes: 0.38 Mechanical Q Value -Qms: 4.21 Total Speaker Q Value -Qts: 0.34 Free Air Resonance -Fs: 22.8 Hz Equivalent Compliance -Vas: 27.1 liters One-Way, Linear Excursion -Xmax: 12 mm Efficiency -SPL 1W/1m: 81.2 dB SPL Effective Piston Area -Sd: 195 cm^2 DC Resistance -Re: 3.2 ohm Nominal Impedance -Znom: Dual 4 ohm Thermal Power Handling -Pe: 175 W Force Factor -Bl: 15.4 here is the new versions Electrical Q Value -Qes: 0.38 Mechanical Q Value -Qms: 4.21 Total Speaker Q Value -Qts: 0.34 Free Air Resonance -Fs: 22.8 Hz Equivalent Compliance -Vas: 27.1 liters One-Way, Linear Excursion -Xmax: 12 mm Efficiency -SPL 1W/1m: 81.2 dB SPL Effective Piston Area -Sd: 195 cm^2 DC Resistance -Re: 3.2 ohm Nominal Impedance -Znom: Dual 4 ohm Thermal Power Handling -Pe: 175 W Force Factor -Bl: 15.4 Specifications: Mounting Depth - 4.5" Mounting Hole Diameter - 7.3" Overall Diameter - 8.7" Bolt Hole Circle - 8" Motor Width - 4.875" Motor Depth - 1.9" Basket Depth - 2.4" Displacement - 0.07 cu. ft. what is the real scoop? i walked away from a set of the old ones on this site for financial reasons, because i can get the new ones substantially cheaper then they were offered here. was that a mistake? are the old ones superior over the new ones? I am looking to use (2) 8" Re Audio subs in a ported box with a Rockford Fosgate 800A2, which should be no big deal for them, but I m wondering if the new is just as good as the old or better, or worse.... thanks ahead of time [/QUOTE]
