Marty Collins Posted November 11, 2016 Report Share Posted November 11, 2016 I just got 4 ground zero 18s gzhwx18 spl and 2 4k amps. I want to build a daily pounder. The manual has ported and 4th order specs. But I've learned to sometimes it's better to not use the specs offered. I was thinking going with ported as I'm able to make it more aesthetically pleasing lol Product name GZHW 18XSPL-D1 Product type Subwoofer chassis Diameter 464 mm / 18.27 Mounting diameter 425 mm / 16.73 Mounting depth 255 mm / 10.04 Magnet dimension 3 x 220x 20 mm Voice coil diameter 75 mm / 3 Round Wire Voice coil winding height 45 mm / 1.77 Top plate height 13 mm / 0.51 Linear excursion (one direction) 16 mm / 0.63 Effective Xmax 45 mm / 1.77 Power handling 4000 W SPL Power Impedance 2 x 1 Ohm Re 1.75 Ohm Res 28.3 Ohm FS 34.3 Hz Qms 6.553 Qes 0.404 Qts 0.381 Rms 19.982 kg/s Cms 0.035 mm/N Mms 606.79 gr BL 23.778 N/A SPL (1w/1m) 92 dB VAS 75.21 L / 2.66 cu.ft Le 2.37 mH Recommended freq. response 35 100 Hz Recommended amplifier power 2000 4000 WRMS @2Ohm (0,5 Ohm) Thanks Link to comment Share on other sites More sharing options...
