About the Adamson B 118
The Adamson B 118 is a front-loaded bass enclosure housing one AW18 Kevlar 18-inch low-frequency driver in a critically damped, vented cabinet. The AW18 is noted as the world's first woven Kevlar diaphragm 18-inch driver, with an extremely high stiffness-to-mass ratio that virtually eliminates cone fatigue and supports long-term reliability. Cabinet construction uses well-reinforced 5/8-inch Baltic birch, resisting vibration at extreme sound pressure levels. The B 118 covers a frequency response of 40-400Hz and is designed to pair with a variety of Adamson full-range enclosures. Its compact, roadworthy build makes it straightforward to transport between live sound and fixed-installation settings.
Adamson B 118 — buyer FAQs
What is the Adamson B 118 and what is it used for?
The Adamson B 118 is a compact, front-loaded sub-bass loudspeaker covering a frequency response of 40 to 400Hz. It is designed to provide high SPL extended bass across live sound applications including drum fill, side fill monitoring, theatre, houses of worship and dance clubs. Its roadworthy construction and compact footprint make it practical for both touring and fixed-installation use.
What makes the AW18 driver in the B 118 distinctive?
The AW18 is described as the world's first woven Kevlar diaphragm 18-inch driver. Kevlar's high stiffness-to-mass ratio virtually eliminates cone fatigue, which supports long-term reliability under sustained heavy use. The driver sits in a critically damped, tuned vented enclosure, and the cabinet itself is built from well-reinforced 5/8-inch Baltic birch to resist vibration at extreme sound pressure levels.
Who makes the Adamson B 118 and where does it sit in their range?
The B 118 is made by Adamson Systems Engineering, a Canadian loudspeaker manufacturer that designs sound reinforcement systems for touring, festivals and permanent installations. The B 118 is a subwoofer designed to complement a variety of Adamson full-range enclosures, functioning as the low-frequency foundation within a wider Adamson system.
What should I check when buying a used Adamson B 118?
Inspect the AW18 Kevlar driver carefully, as cone or surround damage on a single-driver cabinet directly affects performance. Check the vented enclosure for any cracks or port damage that could alter tuning, and assess the Baltic birch cabinet for structural repairs or delamination. Confirm any optional accessories are included. Used B 118 units on 10K Used carry a 21-day warranty covering major functional faults; the buying guide at 10kused.com/used-av-equipment-guide/ covers the full process.
What drives the price of a used Adamson B 118?
Used B 118 pricing varies with overall cabinet condition, the state of the AW18 Kevlar driver, whether any optional accessories are included, and general age and wear from touring or installation use. Check the live listings on this page for current asking prices, and note that many listings include a Make an Offer option.
