What i was getting at is i believe two smaller drivers are more accurate then one massive 12" imo. I believe my spkrs produce great bass ,placement is big but better then some 10" ive had .. Moving massive air no .But transmission designs works well my ole dcm time frame 2000ripped they were small multi driver transmission lines too . Jmho if low end is lacking 40hz down let the sub do that hard and specific work
