Yes, it does. You can correct it with flanking subs, otherwise, it's there. You can't have a midwoofer up off the ground without having a self-interference notch. All the single driver speakers, mini-monitors on stands and tower speakers have it. The only way to smooth it is by blending other sound sources in the upper modal range.
