Overview

The Genelec 7380A is a large SAM studio subwoofer built for monitoring systems that need controlled low-frequency integration, not a general-purpose bass box. Genelec presents it as part of its Smart Active Subs line, and the official materials emphasize system functions, calibration, and serviceability over lifestyle positioning [1][2].

Scientific Validity

\[\Large \text{0.7}\]

Genelec specifies a 16 Hz-100 Hz (-6 dB) passband, short-term maximum SPL of at least 119 dB (30-85 Hz, half-space, 1 m), self-generated noise of at most 5 dB SPL, and 2nd-harmonic distortion of at most 1% from 30 Hz to 85 Hz [1].

The -6 dB limits at 16 Hz and 100 Hz cover a demanding monitoring band, and self-noise at or below 5 dB SPL is far below any practical listening floor [1]. Published 2nd-harmonic distortion at or below 1% from 30 Hz to 85 Hz is low for monitoring use: hearing is weak at these fundamentals, and harmonic products fall mainly at 60 Hz and above [1].

LowBeats measured the 7380A in a GLM-calibrated setup and reported that dominant k3 did not exceed 2% even at 30 Hz and 100 dB SPL [3]. Even at that high test level, harmonic content around 30 Hz stays low. A full independent distortion-versus-frequency dataset is still unavailable.

Technology Level

\[\Large \text{0.8}\]

The 7380A uses Genelec’s own LSE enclosure, active crossovers, a bass management system, ISS standby logic, and SAM/GLM calibration technology [1]. That is a coherent proprietary platform with clear practical value in pro monitoring, because the design is aimed at easier integration and more controlled low-frequency behavior. The underlying amplifier and control technologies are established rather than cutting-edge, so the score stays below the very top tier.

Cost-Performance

\[\Large \text{1.0}\]

CP = 1.0 (no cheaper equivalent-or-better product exists)

Comparison product: N/A.

Function	Genelec 7380a	SVS PB17-Ultra R-Evolution
AES/EBU input/output	Yes [1]	No [4]
7.1 analog XLR input/output	Yes [1]	No [4]
RJ45 GLM network control	Yes [1]	No [4]

The 7380a’s published performance is 16 Hz-100 Hz (-6 dB) with 2nd harmonic at or below 1% from 30 Hz to 85 Hz [1]. The SVS candidate adds app control and Auto EQ, but it still does not match the 7380a’s pro integration stack, so it is not equivalent-or-better for the same system role [1][4]. No cheaper product in the reviewed set was confirmed to match the 7380a’s function set and published numbers.

Reliability & Support

\[\Large \text{0.9}\]

Genelec states that the warranty is two years of parts-and-labour coverage, extendable to five years after registration, and that it aims to support products long after warranty expiry [2]. Repair is routed through authorised service personnel, which fits a complex active subwoofer with protected electronics [1][2]. Genelec also publishes an electrical safety service program that covers selected models, including 7380A units made after 1 March 2024, and affected units are to be checked by authorised service centres [5].

Rationality of Design Philosophy

\[\Large \text{0.9}\]

Genelec spends on functions that matter in a monitoring chain: output control, bass management, calibration, enclosure behavior, and network integration [1][2]. That is a function-first design, not a prestige build, and the product page speaks in numbers and system roles rather than subjective voicing language. The result is a rational product direction even though the feature set is more specialized than many users need.

Advice

Choose the 7380A when your system needs AES/EBU, GLM network control, and multichannel bass integration. If those features are unnecessary, the 7380A’s feature set is more specialized than a basic subwoofer needs to be. At 6,395 USD, it makes sense only when the integration stack is part of the purchase decision and you want the support path Genelec provides [1][2][5].
