If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.
The 8W3v3-4 is best used with amplifier power in the 75W – 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 l) ported enclosure. Detailed enclosure recommendations can be found in the “Specifications” tab.
Continuous Power Handling (RMS) 250 W
Recommended RMS Amplifier Power 75- 250 W
Nominal Impedance (Znom) 4 Ω
Free Air Resonance (Fs) 35.14 Hz
Electrical “Q” (Qes) 0.501
Mechanical “Q” (Qms) 7.071
Total Speaker “Q” (Qts) 0.467
Equivalent Compliance (Vas) 0.54 cu ft / 15.29 L
One-Way Linear Excursion (Xmax)* 0.375 in / 10.0 mm
Reference Efficiency (no) 0.1300%
Efficiency (1 W / 1 m)** 83.24 dB SPL
Effective Piston Area (Sd) 32.02 sq in / 0.021 sq m
DC Resistance (Re) 3.77 Ω
* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
