Gr Bass AT 410-800 ACTIVE SPEAKER BLACK

Historical Context and Positioning in the Range

The GR BASS AT 410-800 Active Bass Cabinet Black fits within GR Bass's modern approach: offering bass amplification systems that are both high-performing and easy to transport. Here, the choice of a 4 x 10-inch format refers to a stage classic (projection, punch, precision), while updating it with a design focused on reduced weight and durability, thanks to a carbon fiber enclosure. Within the range, this model clearly targets "large format" situations: plenty of available power, a wide response, and a sober aesthetic with a black finish.

Who This Amp Is For

This active cabinet is aimed at bassists seeking a stage-ready solution capable of handling demanding contexts: indoor concerts, festivals, quick backline setups, or rehearsals at realistic volume with an energetic drummer. It is also well suited for studio musicians looking for precise sound reproduction (especially in the upper spectrum thanks to the tweeter), while maintaining the authority of a 4 x 10-inch speaker configuration. Style-wise, it performs well across genres requiring definition and attack (funk, pop, modern rock, metal, gospel), as well as rounder, deeper tones if you work your preamp/EQ upstream.

Features and Innovations

The core feature of the AT 410-800 is its active design: the cabinet includes its own amplification (800W RMS), simplifying the rig and reducing dependence on a separate amp head. In practice, you can use it as a high-efficiency "sound platform" by sending the signal from an active bass or your preferred preamp, then powering the unit from mains (220V). Sound reproduction is handled by four 10-inch Jensen/Sica woofers for body and impact, complemented by a 1-inch horn tweeter to add air, articulation, and clarity to attacks. This type of architecture is particularly suitable if you alternate fingerstyle, pick, and slap playing, or if you use effects generating many harmonics (octaver, drive, fuzz, synth bass).

Sound Character

With its 4 x 10-inch format, the AT 410-800 targets a very "stage-oriented" signature: a firm low end, a carrying low-midrange, and a fast response that helps the bass stay clear when the band plays loud. The specified sensitivity of 104 dB SPL indicates an efficient cabinet capable of delivering high volume without any flabbiness. The frequency response (35Hz to 22kHz) suggests solid lows for lower tunings while retaining definition in the highs (string noise, attacks, slap, effect nuances). The carbon fiber construction, often sought for its rigidity, generally contributes to a tighter and more precise reproduction: useful if you want a modern, clean, and punchy sound with excellent note separation.
