Indeed! Load the 15L in a pioneer's Vb = Vas/1.44 = 6 ft^3, 1.56x Fs (measured or if willing to rely on ancient 43 Hz specs) Fb = ~67 Hz tuning for max power, eff. and short of a full size horn you've got one serious mid bass speaker; add a dedicated separate sub or better yet, multiples for the ~20 - 80 Hz BW and your room's gain below ~25 Hz will lower it a bit for all but the lowest LFE soundtracks.
