Hi-Pass Audio Engineering Graphic T-Shirt

A heavyweight black T-Shirt for people who hear the details. The front features a bold “HI-PASS” title above a vintage audio-frequency graphic, while the back continues the technical theme with speaker diagrams, waveform lines, and sound-system notes. It feels like a studio wall translated into streetwear—clean, monochrome, and made for late-night listening sessions, record-store runs, DJ booths, and anyone who speaks in hertz, bass, and treble. The relaxed oversized shape gives it an easy, structured fit, while the substantial cotton fabric lets the print stand out without feeling fragile. Wear it when the playlist gets serious and the room starts to resonate.
