GTFO with that BS. Don't come at me like you're some seasoned, hardcore SPL competitor that speaks in high tech "burping, sweeping" language. I don't need to read things thoroughly. All I need to see is a Newb claiming that burping a couple times is feeding a sub 3k all day.
There is a HUGE difference between a few burps in a tiny, high impedance rise, one note, high frequency sine wave burp box and putting a solid 3k on music ALL DAY. Throw 3k clamped on a 3512 in a music box and walk away. And please make a vid of it.
