At Qtc 1.046 the response carries a roughly 1.5 dB lift peaking near 64 Hz, with an anechoic F3 of 36.4 Hz. That is an impact alignment, not a flat one.\u003c\/p\u003e\n\u003cp\u003eLoaded into a truck cab or cargo floor and firing down, cabin gain fills in below the knee and the result is a punchy, high output system.
