The Next Generation of low bass support.

A new type of subwoofer for home audio or home theater that plays by a different set of rules in terms of frequency depth, size, and cost.


Most people should get the Barnacle subwoofer first to make a 2.1 or 2.2 system and then add the Infrasub later to expand that into a 2.1.1, 2.2.1, or 2.2.2 system.


  • New technology for use in home audio that we developed in secret for years before releasing


  • Uniquely uses car audio driver to achieve new levels of bass realism and dynamics in the home


  • More powerful, more nuanced/musical, smaller, blends better with wide band speakers than other types of subwoofers


  • We’ve even used the Barnacle with our full sized Peavy 15” PA speakers - it gets loud!


  • The Barnacle also scales down to normal and quiet listening levels incredibly well - it is still a nimble 6.5” driver


  • Benefits from the same novel cabinet construction details we developed for our Wide-Band speaker cabinets


  • Compatible with almost any brand of main speakers


  • The vast majority of the high end audio industry is stuck in the past. The Barnacle is the future of bass


  • Now features NRT with Quartz DMS - Noise Reduction Technique using Quartz Diamagnetic Metasurfaces


  • Frequency response up to 120hz-30hz


  • Review from a Triton+Barnacle owner: “I hope the neighbors like King Tubby.”


  • Voltage switchable for international compatibility


  • Ships worldwide


  • 60 day in-home audition, 1 year warranty


  • Email for lead time estimate


Barnacle is now available in Active or Passive versions.


The Active version (photos coming soon) is the same size as the Abby Mk II fullrange speakers to facilitate stacking in a variety of different formations.


We recommend the Passive version to any of our legacy clients who have legacy subwoofer amplifiers. However, we do recommend also upgrading to a new 300 watt Outboard subwoofer amplifier to get the most out of your Barnacle subwoofer.
