Gr Bass NF 410+ -4 NATURAL

Historical Context and Positioning in the Range

With the NF series, GR Bass focuses on speaker cabinets that are both lightweight, robust, and performance-oriented, designed for bassists who want a powerful rig without the bulk. The NF 410+ -4 stands as a "large format" solution: a 4x10 capable of covering many situations, with modern definition thanks to the tweeter and a broad response in the low end. The Natural finish reinforces the cabinet's sober and premium identity.

Who This Amplifier Is For

This speaker cabinet is primarily aimed at intermediate to professional bassists seeking a speaker capable of handling energetic playing (pick, slap, chords) and high volumes. It is particularly relevant for rehearsal (high level, good projection), stage (headroom reserve and dispersion), and contexts where you want to feel the "punch" of a 4x10 without losing clarity. Style-wise, it performs well in rock, metal, funk, pop, fusion, and broadly anywhere the bass needs to remain present and articulated in the mix.

Features and Innovations

The GR BASS NF 410+ -4 Natural is a high-power speaker cabinet built around 4 neodymium 10-inch speakers, a popular choice for achieving a sharp attack, good power handling, and contained weight. The 1-inch tweeter adds brightness and precision, and its 4-position attenuator allows quick adaptation of the upper spectrum to your instrument and style: smoother for an old-school grain, or more open for a modern bass with rich harmonics and well-defined effects. The bass reflex front-ported enclosure helps maintain clear bass, especially on stage, by facilitating forward projection.

With its 4-ohm impedance, this cabinet is designed to get the best out of many amp heads capable of delivering their maximum power at 4 ohms. It thus becomes a solid base for a simple and effective rig: one head + one cabinet, with a level and authority worthy of larger setups.

Sound Character

The typical sonic character of a 4x10 is found here: a feeling of immediate responsiveness, a low-midrange that "pushes," and articulation that highlights right-hand playing. The 10-inch woofers favor a punchy and defined sound, ideal for cutting through a dense mix with guitars and drums. The bass reflex design helps extend the low end, providing more generous bass while maintaining control.

The tweeter, adjustable over 4 positions, is a real musical tool: in the softer position, you get a more discreet upper spectrum, pleasant for a round and organic sound. Opening it up gives you more attack, brightness, and precision on modern techniques (slap, tapping), as well as on effects (octaver, envelope, distortion) that require definition. With a 104 dB sensitivity, the cabinet responds quickly and gives the impression that every watt is used efficiently: useful for staying punchy even without pushing the amp to the extreme.
