Sound is subjective and some like hard hitting bass, others like hifi sounding smooth bass. In my opinion depending on the setting and application, this sub accomplishes both very well. This Subwoofer really impressed me. It is not inexpensive, but the money is well worth it. It is not plug and play like others in the 1600 dollar and below range so, I can understand why some first impressions are not positive. This sub is meant for a more seasoned user who will be doing live sound with delays or dj who is familiar with crossover slopes and so forth. The best setting for this for playback music is L2 when using 15 inch tops with the crossover engaged. L3 when using a 12 inch top with playback music with the crossover engaged. For live sound, use H2 with a 15 inch top or h3 with a 12 inch top both with the crossover engaged. The bass response is massive with these subs and super smooth. When you have them in the L setting, the limiter light will come on occasionally, but these speakers have several layers of circuit protection through its dynamic limiter and DSP so they keep going all night without any issues. The sound is also not affected like other manufactures with hard limiters that make their subs output really drop when the limiters come on. The amp also stays super cool for a sub without fans. I play latin, hip hop reggae, rock, and top 40 through these and they sound rock solid. I recommend to anyone looking to upgrade to a professional sub with additional features with read more super low and powerful bass.
