Z-18 V.3 D1 - Sundown Audio 18" 1500 Watt RMS Dual 1-Ohm Subwoofer
- SKU #: 90584
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.
