        Pros and cons

        According to our specialists
        • 91 dB sensitivity provides strong output with moderate amplification
        • 3-inch copper voice coil and 200 W rating improve power handling
        • Vented pole piece and cast aluminium chassis minimise compression for consistent bass
        • Large equivalent volume Vas 205 liters needs a sizable vented enclosure
        • Relatively heavy net weight of 8.9 kg increases handling effort

        Product details

        SB Acoustics SB34NRXL75-8 12" Woofer

         

        The SB34NRXL75-8 12" woofer features a proprietary composition paper cone with a special coating. The rubber surround has been carefully chosen to properly dampen the cone movement. The open structure cast frame has been specially engineered for minimum reflections good air flow. Extra-large magnet with dual shorting rings and vented pole piece. This woofer could be used in various boxes but will likely require some boost on the low end to extend the lower frequencies.
