Sundown Audio Z-15 V.3 D1 15" 1500 Watt RMS Dual 1-Ohm Subwoofer

The third generation Z series woofer builds upon several 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 in it's 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. Only the 10" model is no longer available -- the 12/15/18 are still in full production.

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.
