        Product details Purifi PTT5.25X04-NAA-05

        Purifi PTT5.25X04-NAA-05 5.25 inch Extended Woofer

         

        The Purifi PTT5.25X04-NAA-05 is a 4 ohm extended woofer developed to deliver uncompromised sound quality across bass and midrange frequencies. With a resonance frequency of 29 Hz and a total Q factor of 0.27, it is well suited for compact vented or sealed enclosures where controlled low frequency extension is required.

         

        The driver features a black anodized aluminum cone combined with a long stroke motor system that maintains low distortion across the full excursion range. Linear Xmax of plus minus 9.8 mm and mechanical excursion capability of plus minus 14.0 mm ensure reliable output even at high listening levels, while maintaining excellent transient control.

         

        With an effective piston area of approximately 85 cm2 and a sensitivity of 84.9 dB at 2.83 Vrms at 1 meter, the PTT5.25X04-NAA-05 balances efficiency with precision. The 39 mm diameter voice coil with four layers and CCAW winding contributes to high thermal stability and consistent performance under load.

         

        Designed and manufactured in Denmark, this extended woofer is ideal for high end multiway loudspeakers, compact high output monitors, and advanced DIY projects where ultra low distortion and accurate sound reproduction are essential.
