Hey maker community! 👋

Sharing hard-won audio design lessons for KT148A voice chip users:

The volume struggle is REAL when:
• Using <1W film speakers
• Housing design ignores acoustics

But good news! We found:

🔹Paper cone speakers (AliExpress) work wonders
🔹Proper venting > amplifier mods
🔹Size DOES matter for speakers

Anyone else solved this differently? Let's compare notes!
