Maybe some could try MC2 1250 on subwoofers in their house, and tell me if it lacks sound quality or power driving 2x 2x15s per channel in a house.
I came here with a lot of experience in the pro audio world.
Perhaps you're underestimating what it takes for reference level playback of the LFE spec (3hz-120hz), including all redirected bass management. Not too many fully grasp what a system is facing to achieve ref levels and cover the spec.
Hit 120dB plus peaks at the LP. Be mindful of the EL curves and audibility threshold of LF/ULF. Our hearing just does not stop at a certain point, it just requires much greater SPL to achieve audibility. Remember, loudness, and sound pressure are entirely different and frequency and level dependent.
About 20hz, 75dB is needed for audibility. At about 16Hz, 85dB is needed. At 10Hz, about 100dB SPL, and an octave lower at 5hz, audibility threshold is about 110dBSPL.
Consider a sub system with a given performance SPL level at a given frequency. Now, every octave lower requires a quadrupling of like powered drivers to maintain a certain dBSPL. This elevates system requirements incredibly, when merely attempting to cover the LFE spec at reference level. Thus, you see the high power 8 driver (on up) sub systems. Myself, I've got four 18s, four 15s. Add in LT EQ'ing, to properly shape the response of a small sealed box, the power requirement climb significantly.
High performance HT is another world from performance pro audio.
