This sub is loaded with an incredible driver. You can’t bottom the driver out. It smooth, bottomless and most important to me, It’s musical.
I’ve owned a dozen or so subs from other vendors. Some excelled at knocking pictures off the walls, but they were less than acceptable in music. The RBH subs excel in low volume music listening, jazz, classical etc. Should you desire to watch the cats fly from the room, they can do that too.
Shane designs incredible subs. Their current line of twin 12” flavors can suck your lungs out then put them back. They can be unnerving and kinda scary.
