DS18 Pro ZT 6x9 Speaker Grill

Custom 6×9 Speaker Grill – Honeycomb Design (Polk DB692 Compatible)

This is a custom-designed 6×9 speaker grill built to fit the Polk DB692 speakers and other similarly sized 6×9 car-audio drivers. The grill uses a reinforced honeycomb pattern that provides strong protection while maintaining airflow and sound clarity. Its modern, aggressive design makes it perfect for demo boxes, portable audio rigs, enclosures, and automotive installs.

This is the same grill shown in the sample product-style photos, printed in black with a red accent layer.

✨ Features

• Perfect fit for Polk DB692
  Modeled around the DB-series mounting footprint and tweeter height.
• Wide compatibility with most 6×9 speakers
  Standard bolt spacing works for nearly all manufacturers.
• High-flow honeycomb layout
  Protects the cone and tweeter without choking output.
• Rigid outer frame
  Designed to withstand real-world handling and vibrations.
• Two-color print friendly
  Accent color pops through the honeycomb for a premium look.
• Support-free print
  Designed to print cleanly flat on the bed.

🖨 Recommended Print Settings

• Orientation: Flat on the print bed, front facing up
• Layer Height: 0.16–0.20 mm
• Perimeters/Walls: 3–5 walls for stiffness
• Infill: 15–25% (Gyroid / Grid)
• Material:
  • PLA for general use
  • PETG / ABS / ASA for automotive or outdoor installs
• Supports: None

For two-color results, do a filament change right before the honeycomb bridges begin.

🔧 Installation

1. Place grill over the Polk DB692 speaker.
2. Align the mounting holes.
3. Install with M4 screws, #8 hardware, or your existing speaker screws.
4. Tighten evenly — do not over-tighten.

The design ensures clearance over the DB692’s tweeter pod and surround.

📌 Notes

• If you're using a non-Polk 6×9, a 1–2% scale adjustment may improve fit.
• Feel free to remix the lettering or outer shape; the flat print surface makes edits easy.
• The model is ideal for case builds, sub boxes, marine setups, and custom audio displays.

Custom 6×9 Speaker Grill – Honeycomb Design (DS18 PRO-ZT 6×9 Compatible)

This is a custom-designed 6×9 grill built to fit the DS18 PRO-ZT 6×9 midrange speakers. The DS18 PRO-ZT series has a deeper basket, larger cone area, and a raised bullet tweeter, so this grill is designed with extra internal clearance while still keeping the aggressive honeycomb style.

Perfect for demo rigs, wall builds, door panels, case installs, or any setup where you want maximum protection and airflow without covering the look of the PRO-ZT.

✨ Features

• Designed for DS18 PRO-ZT 6×9 speakers
  Clearances optimized for the raised bullet tweeter and deeper cone geometry.
• High-flow honeycomb protection
  Strong outer frame + open honeycomb pattern keeps the cone safe without restricting output.
• Rigid, impact-resistant geometry
  Ideal for high-SPL builds and vibration-heavy environments.
• Support-free, flat printing
  Prints cleanly on any machine with no supports needed.
• Great for dual-color prints
  The honeycomb outlines look amazing with a contrasting accent color behind them.

🖨 Recommended Print Settings

• Orientation: Flat on the bed (front up)
• Layer Height: 0.16–0.24 mm
• Walls/Perimeters: 2-3 for strength (recommended for SPL builds)
• Infill: 15-20% Gyroid / Adaptive Cubic
• Material:
  • PETG/ASA strongly recommended for car doors or high-heat installs that may see alot or direct sun
  • PLA + works for indoor rigs
• Supports: Screw Holes Only

🔧 Installation

1. Place the grill over the DS18 PRO-ZT 6×9.
2. Align the mounting holes with the driver.
3. Install using #8, M4, or your existing speaker screws.
4. Tighten evenly to avoid flexing or warping the grid.

The spacing provides safe clearance over the PRO-ZT bullet tweeter while maintaining a snug overall footprint.

📌 Notes

• Designed with the deeper DS18 PRO-ZT basket in mind; should also fit some other 6×9 drivers.
• Can be customized upon request.
