The PRO-ZT6SL gives you full-size output in a super shallow 2.15” profile, built to fit tight spaces without sacrificing volume or clarity.
Shallow Build
At just 2.15” mounting depth, the PRO-ZT6SL is made for motorcycles, doors, pods, and custom panels where space is limited.
2-Way Power
A built-in bullet tweeter with neodymium magnet delivers crystal-clear highs. Combined with a 6.5” mid-range cone, the PRO-ZT6SL plays strong from 85Hz–20kHz, giving you clean vocals and sharp detail in one drop-in speaker.
Engineered for Real-World Use
The water-resistant cone and treated cloth surround are made to withstand moisture and the pressure of daily use.
Let It Rip
With 200W RMS / 400W MAX, 4-ohm impedance, and 96.5dB sensitivity, this speaker gets loud fast, even on lower power. It’s the perfect blend of output and efficiency in a frame that fits anywhere.
Get full-range clarity without giving up space using DS18’s PRO-ZT6SL.
