Gr Bass AT 110-4 BLK BLACK

Historical Context and Positioning in the Range

With the AeroTech series, GR Bass has built a reputation around a simple concept: offering professional bass cabinets with an impressive weight-to-performance ratio, thanks to a carbon fiber design. The AT 110-4 BLK follows this logic by targeting bassists who want the "big" sound of a real cabinet without the volume and transport constraints associated with traditional wooden speakers.

Within the range, this 1x10 format is an ideal solution as a main cabinet for quiet to moderate settings, or as an extension to create a compact stack (for example, by doubling with a second cabinet) while remaining extremely mobile.

Who This Amp Is For

The GR Bass AT 110-4 BLK is aimed at demanding beginner bassists as well as experienced musicians seeking a reliable, lightweight, and precise cabinet. It is particularly suitable for rehearsals, home studios, sessions, or small to medium venues when you want to maintain excellent clarity without bulk.

Its 1x10 format responds quickly and highlights fingerstyle, pick playing, slap, as well as modern active basses. Thanks to the adjustable tweeter, it can also be tamed for vintage aesthetics (rock, soul, reggae) or rounder tones like jazz.

Features and Innovations

Here, there are no channels or built-in effects (it's a cabinet), but everything is designed for efficiency: a load capable of handling 300W RMS, a 4-ohm impedance to draw maximum power from many heads, and a performance-oriented architecture. The carbon fiber provides an "immediate response" feel and excellent mechanical stability, while the cabinet tuning (with rear bass reflex according to the series design) helps achieve fuller lows despite the small footprint.

The 1-inch tweeter features a 4-position selector : handy for adjusting the amount of treble to suit your instrument, style, or room (for example, reducing high frequencies in a reverberant space or opening them up for very articulate slap playing).

Sound

The AT 110-4 BLK aims for a clean, fast, and detailed reproduction. The 10-inch driver delivers a sharp attack and clear low-midrange, ideal for cutting through a mix without pushing volume. The tweeter, once dialed in, adds the air and definition needed for harmonics, ghost notes, modern sounds, and effects (octaver, synth, chorus) that require precision.

With its 103 dB sensitivity and frequency response up to 22 kHz, it easily provides a sense of projection while retaining the option to switch to a rounder sound via the tweeter adjustment. In short: a compact cabinet that prioritizes clarity, dynamics, and control rather than a "muddy" bass.
