#subwoofer #bass #bassboosted Ever wonder if a 21" sealed subwoofer can create bass you can feel? Check out this build as I take an SB Audience Rosso 21SW800, where I test whether or not room gain can help me reach subsonic frequencies in my room. Tested and revealed both room gain and bass that you can feel. Build Plans: https://toidsdiyaudio.com/product/ear...
