Historical Context and Positioning in the Range
GR BASS has established itself among bassists seeking a modern sound, effective projection, and easy-to-transport gear. The AT 112H-800 clearly fits this philosophy: an active 1x12 speaker cabinet designed to offer high power output and faithful reproduction of playing, while remaining extremely lightweight. In a compact configuration, it targets musicians who want to limit the number of elements to carry without sacrificing impact or definition.
Who This Amplifier Is For
This active speaker cabinet is aimed at intermediate to professional bassists who need a simple, quick-to-set-up system powerful enough to transition from rehearsal to live performance. It is particularly suitable for contexts where portability is crucial (small stages, frequent gigs, studio sessions). Regarding styles, it excels whenever a clear and articulated bass is desired: funk, pop, modern rock, metal, gospel, electro, or any repertoire requiring sharp attacks and solid low-end presence.
Features and Innovations
The GR BASS AT 112H-800 combines integrated amplification (220 V mains power) and a 2-way speaker system (woofer + tweeter) to offer an all-in-one performance-oriented solution. The advantage on the ground is achieving a high sound level and consistent response without multiplying devices: you plug in, power up, and play. The 4-ohm load, combined with a rated sensitivity of 99 dB SPL, promotes effective projection and excellent efficiency, useful to remain audible in a dense mix, especially with energetic drums or distorted guitars.
Sound Character
With its 12-inch speaker, the AT 112H-800 targets a balance highly sought after by bassists: present but controlled lows, a solid low-midrange to "carry" the band, and mids clear enough to detail fingerstyle, slap, or pick playing. The 1-inch tweeter adds the air and precision needed for harmonics, modern sounds, and effects (octaver, envelope, overdrive) while maintaining clarity. The carbon fiber construction contributes to a sensation of fast and clean response, with good control when increasing volume: notes remain defined, and attacks do not collapse. Result: a sound that can be very hi-fi if your preamp/signal chain is neutral, or conversely very "punchy" if you boost the low-mids and transients.
