  • Downward Firing Subwoofer Frequency

    I have searched far and wide but cannot find the answer to this question. How high can a downward firing subwoofer rightfully play?

    My assumption is not much past 150hz if that. I have been looking at some of the popular FAST designs and thought of the idea of a shallow woofer/subwoofer with a pair of small fullrange drivers in a slim compact tabletop/soundbar/blose wave radio.

    If it can be crossed to say 300-500hz, this could work quite well, but I dont believe it can

    I believe you're correct.

      If you used a woofer could you reach a higher crossover point? Anyone?

        You could probably run to at least 300Hz, but the question is why would you? That would make it easily directionally locatable.

          I think for closely spaced mains, like in a small desktop/soundbar, imaging and soundfield concerns are reduced. So as long as the sub driver is happy at the desired cutoff it should not drastically impact overall sq up to about 300hz or so. Much above 300 and you are getting into midrange territory and that could degrade the experience to a noticeable level. I would make a test enclosure for anything above 300hz and anything above 150 if the mains are spaced farther apart than 12-18" or so.
