Subwoofer Bass Test 5.1 | 80–20 Hz Sweep | Will Your Room Survive? 4K HDR

🔊 Subwoofer bass test in real 5.1 surround: an 80 → 20 Hz sweep, a 25–30 Hz heartbeat and three bass drops push a smart apartment to destruction – speaker check first, then the neighbour, a police helicopter and finally the walls give up. Watch in 4K HDR. 🔊 Start at low volume, then turn it up – the bass gets serious. 🔔 A new surround & 3D audio test every week → Subscribe:    / @0x0ndra   ━━━━━━━━━━━━━━━━━━━━━━ 🎛 𝗛𝗢𝗪 𝗧𝗢 𝗣𝗟𝗔𝗬 𝗜𝗧 ━━━━━━━━━━━━━━━━━━━━━━ 1️⃣ Best in the YouTube app on a TV, streaming box or console connected to your receiver or soundbar (HDMI / eARC). ✅ 5.1 works on most smart TVs (2021+), Chromecast, Apple TV, Roku, Fire TV, Xbox, PS5 2️⃣ In the player settings turn on "5.1 surround sound" (if offered). 3️⃣ No subwoofer? The bass is mixed into the front speakers too, so phones, laptops and headphones still get the low end (just not the deepest part). 4️⃣ Start LOW. Protect your speakers – if anything rattles, distorts or bottoms out, turn it down. ━━━━━━━━━━━━━━━━━━━━━━ 👂 𝗪𝗛𝗔𝗧 𝗧𝗢 𝗟𝗜𝗦𝗧𝗘𝗡 𝗙𝗢𝗥 ━━━━━━━━━━━━━━━━━━━━━━ 🔈 Speaker check (0:07) – every channel is named, then plays alone: L, C, R, Ls, Rs and the subwoofer 🎚 Sweep 80 → 20 Hz (1:29) – the frequency is on screen: note where your sub fades out 🚁 Police helicopter (1:44) – the rotor moves from behind you across the front and away to the right rear 💓 Heartbeat 25–30 Hz (2:23) – felt more than heard; only a capable sub reproduces it 💥 Finale (2:42) – the hardest drop, all channels at once ━━━━━━━━━━━━━━━━━━━━━━ ⏱ 𝗖𝗛𝗔𝗣𝗧𝗘𝗥𝗦 ━━━━━━━━━━━━━━━━━━━━━━ 0:00 Intro 0:07 Speaker Check (channel ID) 0:34 Level 1 – Punch 1:13 Drop 1 1:29 Warning – Sweep 80 → 20 Hz 1:44 Level 2 – Police Helicopter 2:07 Drop 2 2:23 Level 3 – Heartbeat 25–30 Hz 2:42 Finale 3:13 Aftermath 3:32 Encore ━━━━━━━━━━━━━━━━━━━━━━ 🔥 𝗠𝗢𝗥𝗘 𝗙𝗥𝗢𝗠 𝗔𝗩 𝗧𝗘𝗦𝗧 𝗟𝗔𝗕 ━━━━━━━━━━━━━━━━━━━━━━ 🔊 5.1 Speaker Check (pink noise) →    • Dolby 5.1 Surround Sound Test | Speaker Ch...   🌌 5.1 Surround Demo – From a Drop to the Galaxy →    • Dolby Atmos 5.1 Surround Sound Demo | From...   🎵 5.1 Music Experience (10 Worlds) →    • Dolby 5.1 Surround Sound Test | Music Expe...   📺 8K HDR Wildlife OLED Demo with 5.1 →    • 8K HDR Wildlife | OLED TV Demo with Dolby ...   ▶ All speaker tests →    • Channel Check – Surround Speaker Tests   🔔 Subscribe →    / @0x0ndra   ━━━━━━━━━━━━━━━━━━━━━━ 👤 𝗖𝗥𝗘𝗗𝗜𝗧𝗦 ━━━━━━━━━━━━━━━━━━━━━━ AV Test Lab by 0x0ndra · Concept, sound design, mix & edit No real apartment was harmed. 🇨🇿 Test subwooferu jako 4minutová atrakce: chytrý byt zkontroluje reproduktory a pak zesiluje, dokud to nevzdá soused, policejní vrtulník i zdi.
