Not every custom vehicle has to scream for attention.
Some builds are about something quieter.
A beautiful interior. Natural colors. Good music. An open road. And a vehicle that feels a little more like you every time you climb inside.
The Mushroom Flatline Speaker Grill was designed for that kind of ride.
It's for the person who feels at home outdoors. The person who appreciates organic shapes, earthy colors, forests, trails, mountains, fieldsβand those strange little pieces of natural beauty most people walk right past without ever really seeing.
And maybe that's exactly why this one belongs in your vehicle.
There's something almost architectural about a mushroom.
The sweeping cap.
The radiating gills underneath.
The strong central stem.
The symmetry.
The Mushroom Flatline takes those natural forms and turns them into functional automotive artwork.
A broad green mushroom cap rises from the center of the grill, while individually sculpted gills radiate underneath it. The stem flows downward into long open channels, with small blades of grass emerging at its base.
And behind everything sits a densely perforated acoustic background that lets the speaker breathe.
It's organic.
It's symmetrical.
It's unexpectedly beautiful.
This isn't the skull.
It isn't the flames.
And that's exactly the point.
The Mushroom Flatline has a completely different personality.
It's for the mellow cruiser. The outdoorsman. The nature lover. The person whose vehicle might spend Saturday night cruising through town and Sunday morning heading down a dirt road.
It can look at home in a classic cruiser, a pickup, an SUV, an adventure vehicleβor simply a beautifully kept daily driver whose owner wants something more interesting than factory black plastic.
There's a quiet confidence to it.
Maybe it represents the woods.
Maybe it represents growth.
Maybe it represents the strange perfection of the natural world.
Or maybe you simply looked at it and thought:
That's beautiful. I want that in my truck.
That's reason enough.
Our Flatline Series is built around a simple idea:
The Mushroom design stays close to the traditional profile of a 6Γ9 speaker grill, making it an excellent choice when installation space is limited or when you want your custom work to feel integrated into the vehicle.
But there's another advantage here.
The perforated background provides hundreds of openings for sound, while the mushroom itself incorporates open areas through the stem and surrounding structure.
The artwork doesn't simply sit in front of your speaker.
The artwork becomes part of the acoustic opening.
That means you can add something beautiful to your interior without putting a giant wall between your speaker and your ears.
The centerpiece is a large sculpted mushroom rendered with enough dimensional detail to give the Flatline grill depth without turning it into a full sculpture.
The green cap is punctuated with organic openings that continue the natural theme while allowing additional sound passage.
Underneath, the gills fan outward in a beautiful radial pattern, highlighted to bring out the intricate texture.
The stem itself is opened with long vertical channels rather than being formed as one solid block.
Small grass details complete the scene at the bottom.
The result feels less like a graphic placed onto a speaker grill...
Because these grills are printed to order, customers who don't mind waiting can submit a custom color request and have their set produced in colors selected to coordinate with their vehicle's interior.
Available custom colors include the commercially available PCTG colors shown in the color chart to the right.
Earth tones. Greens. Browns. Blues. Neutral shades. Something brighter.
Make it blend in.
Make it stand out.
Every grill is professionally 3D printed using premium PCTG, chosen for its excellent strength, heat resistance, UV stability, and durability inside automotive interiors.
Each piece is printed with precision and individually inspected for quality before it ships.
Because something inspired by the outdoors ought to be able to handle a little life.

There's something different about bringing a little bit of nature into a machine.
Cars are steel.
Glass.
Plastic.
Wires.
Engines.
Electronics.
And right in the middle of all of it...
Something organic in a mechanical world.
Something peaceful in a machine built to move.
Something that reminds you that no matter how far the road takes you, the natural world is never really that far away.
Maybe that's what makes this design work.
It doesn't need to be aggressive.
It doesn't need to be loud.
It doesn't need to explain itself.
Roll the windows down.
Turn the music up.
Take the long way home.
Changing the world by bringing art and beauty into everyday driving...
one speaker grill at a time.
Well...
actually, one pair at a time.
