Many of our customers describe the bass as “thunderous.” Steve Guttenberg of CNET described the bass of one of our products this way:

Bass depth and definition were well-ordered... There's no muddiness down there of the sort I get from a lot of tube amps.

From a technical perspective, ZOTL amps have a linear frequency response below 10hz.

To put that number into perspective, the lowest most full-range speakers go to is about 20hz, with most being closer to 28-32hz. Even REL, arguably the world’s top subwoofer manufacturer, their flagship subwoofer goes down to 14hz.

So, whatever is in the music, our amps will be able to deliver.
