Yes, but it's the quality of boom. Most subs sound like thunder to me. The note is struck and then there is a residual boom that echoes a couple times before dissipating. It's not that the Ultimo doesn't strike with authority. It does--but then it stops. There is no echoing thunder. That is what separates it from other subs. All other subs just sound sloppy next to the Ultimo. The best way for me to describe the sound is a super midbass.
I also want to hear it compared to a Dayton HO. Two people near me have the Daytons. We will test them side by side in our subwoofer showdown.
