The HTM-200 are specifically designed for a seamless blend with a subwoofer using an 80Hz crossover.
Not true.... using a sealed speaker like the HTM-200, which has a gradual low end roll-off, the difference in the "valley" you might experience between the speaker and sub when comparing an 80Hz crossover vs 100Hz will only be 3dB... Typical in-room peaks and valleys in frequency response just due to room reflections and boundaries are 10 - 12dB....
