3D Printed Eggs
Alright, I think I've posted a previous version of these before but I can't remember. If I did, they were probably torn to shreds, so I've gone back to the drawing board.
Setup: Apple TV 4K source → WiiM Amp (power, EQ, room correction). Considered bi-amping with miniDSP 2x4 but wanted to keep things simple/cheap and retain full ATV remote control.
Drivers & Enclosures:
- Dayton PS180-8 in a ~0.2 ft³ (350 in³) sealed enclosure. Planning butyl mat on the walls + polyfill, which should bring Qtc from around 0.8 (unfilled) down to ~0.72-0.75.
- Peerless BC25SC08-04 in a tiny ~0.012 ft³ (21 in³) enclosure with a 20mm negative offset, ~5.95" CTC.
Crossover: External LR4 around 2500 Hz (approximations from manufacturer data) 750 µH / 12 µF on woofer, 330 µH / 22 µF on tweeter. Might measure and refine once it's all together depending how much time it takes off my life.
Placement: Speakers ~76" apart, 12–18" from front wall, tweeters at/near ear level (wall mount or stands, wife's choice). Listening ~12 ft back on the couch.
This is mainly for streaming TV/movies through the Apple TV plus general music around the house — not a dedicated critical listening setup. Hoping room gain gets these decent without a sub, but I'm realistic — should still be a big upgrade over our old $250 soundbar/sub combo after 4 years.
Printed in PETG or PETG-CF (6–8 perimeters, 40% gyroid infill, heat-set inserts). Final finish: prime/paint/clear. Half-ass modeled the whole living room for scale.
Questions, comments, concerns welcome, just don't be a jerk. Thanks!
Yes, I used AI to write this, I just typed whatever came to mind and it was a jumbled mess. Me no good words, me good build stuff. Fight me.
