The third generation Z series woofer builds upon many years of customer and SPL competition experience to create an exceptional combination of low distortion and high output at a reasonable price. The Z v.3 line carries a conservative 1500-watt RMS rating. This line features a beefy 8-layer flat-wound aluminum voice coil wound on a black aluminum former. As with our SA series these woofers also feature dual faraday rings for lower levels of distortion and higher power delivery from your amplifiers.

The Z v.3 line has been a staple in our line-up since 2011 and it quickly became our best-selling “big boy” driver of its time as our top-of-the-line model (until the launch of the X and Z v.4). It remains in our line-up for customers after a more “traditional” driver and/or a shallower mounting depth than the X and Z v.4 series. The 10″ model is no longer available — the 12/15/18 are still in full production.

As discussed above the Z v.3 is a more “traditional” subwoofer design. It does not feature the same Mega-Roll surround or massive, patented frame technologies as our larger lines / X series. It has a more aggressive & punchy sound that many folks still enjoy. It is also the best choice for higher-frequency SPL burp classes in our ferrite-based subwoofer line.

Anyone who has been around the competition scene for long is well aware of the reputation built by the Z v.3 series woofers. They hold a slew of world championships in bass race, bass boxing, and various SPL competition formats.
