Genelec 8330A

Mostly called accurate and neutral. Audio Science Review heard the right tonality within a minute, Sound On Sound and MusicRadar describe the typical clear, detailed Genelec sound, Bonedo and delamar call it neutral (delamar after calibration), 13th Note finds it less coloured than KEF's LSX, and owners on Thomann, Gearspace, ASR and Reddit call it flat and true. The dissent is about voicing and mood: Wolves Unite and a Gearspace owner hear a forward, mid-forward Genelec character, an ASR owner who replaced Harbeths finds it less enjoyable at low volume, and a Reddit owner prefers cheaper Yamaha HS8s for casual listening.

“It doesn't take but a minute of listening to know that a) the tonality is right and b) matches other Genelec speakers.”

Audio Science Review (amirm, nearfield listening test)

“Uncalibrated, on stands and positioned correctly in my listening room, both pairs of monitors delivered the characteristic clear, detailed, revealing Genelec sound.”

Bob Thomas, Sound On Sound

“they tend to push the sounds forward more compared to the other speakers in other words you get that in-your-face sound”

Wolves Unite (YouTube; one-week loan through Genelec Japan, on Genelec's 80 series)

Generally deep and punchy for a 5-inch woofer, with a split over whether you need a subwoofer. delamar calls a sub a bonus rather than a must, Gearspace and Thomann owners are surprised by the low end without one (one uses it as a hi-fi pair at 2.5 m in a 40 m² living room), and Reddit owners mix on it without ever adding one. Sound On Sound, Audio Media International and MusicRadar would add Genelec's 7350A sub for bass-heavy or electronic work, ASR and Reddit owners call a sub almost required, and Bonedo found its deep port tuning a little boomy in its room before calibration.

“The 8330's also have a surprising amount of low end without the sub.”

pw2005, Gearspace (owner)

“However, if I were recording and mixing tracks with a lot of bass — especially electronic bass — I’d probably want to add the matching 7350A sub.”

Bob Thomas, Sound On Sound (on stands in a treated listening room)

“Wie dem auch sei, die Boxen sind für meinen Geschmack etwas zu boomy, wodurch der Punch und die Transienten-Abbildung leider leicht leidet.”

Felix Klostermann, Bonedo (German: “either way, for my taste the speakers are a little too boomy, which slightly costs punch and transient definition”; on stands behind the desk, before GLM calibration)

Mostly clean and uncoloured. Bonedo hears plenty of midrange detail and can work fatigue-free for long sessions, a Thomann buyer says it colours nothing in the mids, and MusicRadar describes a midrange that is not particularly forward. Audio Science Review measured resonances around 2 kHz but found removing them made the sound more closed in. A Gearspace owner comparing it with Dynaudio LYD 48s hears a mid-forward voicing — and has come to value it for vocals — while another owner found the GLM correction scooped the midrange on some older records.

“In den Mitten werden ebenfalls eine Menge Details offenbart, sodass sich mit diesen Speakern selbst über einen längeren Zeitraum ermüdungsfrei arbeiten lässt.”

Felix Klostermann, Bonedo (German: “the mids also reveal a lot of detail, so you can work on these speakers fatigue-free even over long periods”)

“they are not coloring anything in the mids”

Thomann customer review (Veon, May 2017; owner)

“I prefer the LYD sound, relaxed and extended on the top and am learning to value the 8330s mid forward sound.”

Heartfelt, Gearspace (owner, nearfield with GLM, alongside Dynaudio LYD 48s)

The familiar Genelec top end — clear and crisp. MusicRadar hears a very clear top end, Thomann owners call it smooth, flat and revealing, and an ASR owner found the 8330A less fatiguing than the 8030C. Bonedo and delamar both hear a slight Genelec-typical emphasis ("minimally metallic", "crisp") that never tired them, and a Korean owner keeps hearing the brand's treble character but calls it mild. The critics: Wolves Unite finds the voicing forward to the point of exaggeration, and a Gearspace owner hears sharp upper mids with little air on top next to Dynaudio LYD 48s.

“This means very clear top-end and good articulation but not particularly forward mid range.”

Jon Musgrave, MusicRadar

“Die Höhen sind zwar etwas betont und auch minimal metallisch, was ich hier allerdings noch nie schwierig empfand.”

Felix Klostermann, Bonedo (German: “the highs are somewhat emphasised and minimally metallic, which I have never found difficult here”)

“the 8330's have a slightly sharp upper-mid and seem veiled in the extreme top end, in other words, not much air.”

Heartfelt, Gearspace (owner, nearfield with GLM)

Generally described as larger than the box. delamar hears a spacious stage with every element well separated front to back, Audio Media International found it sounded larger and fuller-range than its size suggests, and Wolves Unite felt the speakers blend into the room after calibration. 13th Note hears more depth and accuracy than KEF's LSX but gives the KEFs the edge on front-to-back stage depth.

“zeichnen sich alle Elemente sehr gut getrennt voneinander ab und bilden eine geräumige Bühne”

Felix Baarß, delamar (German: “all elements stand out well separated from one another and form a spacious stage”)

“the Genelecs were much closer in performance than I expected and sounded larger, with a greater bandwidth than their size would suggest”

Nigel Palmer, Audio Media International (compared with his Trinnov-corrected mastering monitors)

“whilst the kefs are better with forward and aft soundstage depth”

13th Note HiFi Reviews (YouTube; compared with KEF LSX)

A clear strength. Bonedo rates the stereo performance very high with every instrument easy to place, a Thomann owner using them as hi-fi speakers at 2.5 m finds the image wide and stable, and an owner on Reddit calls the stereo field very transparent. delamar's only quibble is that the phantom centre could stand out a touch more.

“Das Stereoverhalten ist auf einen sehr hohen Niveau, wodurch einzelne Instrumente auf der Stereobühne eindeutig lokalisierbar sind.”

Felix Klostermann, Bonedo (German: “the stereo behaviour is at a very high level, so individual instruments can be clearly located on the stereo stage”)

“das Stereobild ist breit und stabil, Stimmen und Instrumente werden deutlich lokalisiert.”

Thomann customer review (Lachi, January 2019; German: “the stereo image is wide and stable, voices and instruments are clearly located”; hi-fi use at 2.5 m in a 40 m² living room)

“I find the stereo field very transparent on the genelec 8330A and overall pretty flat frequency response.”

razormane1, r/studiomonitors (owner, mixing in a small room)

Clear and revealing. Sound On Sound calls it detailed and revealing, Bonedo hears very clean, precise resolution, owners on ASR, Gearspace and B&H hear details they had missed for years, and a Gearspace owner says the detail never distracts from the bigger picture. Audio Media International found its own far costlier Trinnov-corrected system more resolving, if by less than expected, and an ASR owner found his Harbeths clearer at very low volumes.

“As for the sound, it was all already written... smooth, effortless, amazing detail.”

sajgre, Audio Science Review forum (owner, desktop nearfield with a 7350A sub and GLM)

“They are also some of the more detailed speakers but these details don't distract you from the bigger picture.”

Jantex, Gearspace (owner)

“they are phenomenal at low volumes, miles ahead of the Genelecs in enjoyment and clarity.”

lappy, Audio Science Review forum (owner of 8330As and a 7350A, on the Harbeth SHL5 Plus they replaced)

Sources split on headroom, and the split tracks level, distance and bass content. MusicRadar, delamar, 13th Note and Thomann owners find it punchy and plenty loud at the desk — delamar turned it up without distortion and an ASR owner finds it uncomfortably loud in the nearfield. Audio Science Review saw the clip light come on with bass-heavy music even in the nearfield and blames the limited amplification, Nuyes measured compression at 96 dB, Bonedo found the deep port tuning runs out of level early on bass-heavy music (with port turbulence on techno), and an ASR owner calls it fine for a desk but short of oomph as main speakers, even with a sub.

Easy to set up on a desk, with caveats about the room. Bonedo praises how easily the Iso-Pod aims it and its large, colour-free sweet spot, Audio Media International stood it on top of its main speakers, and Audio Science Review found more vertical leeway than average. Its directivity is less even around the crossover than Genelec's best, and Genelec recommends upright use with the acoustic axis aimed at the listener. GLM corrects bass peaks for one listening spot but cannot fix a bad room (Wolves Unite, owners on Reddit and Gearspace), and a Gearspace owner found it band-limited when set too far apart and much fuller in the bass pulled in close.

“Dank des elliptischen Waveguides ist der Sweet Spot groß und vor allem frei von Färbungen”

Felix Klostermann, Bonedo (German: “thanks to the elliptical waveguide the sweet spot is large and above all free of colouration”)

“Vertically response is above average with good bit of leeway above and below tweeter axis before you get into trouble”

Audio Science Review (amirm, Klippel NFS)

“GLM doesn't fix a bad sounding room.”

Popxorcist, r/genelec

Strongly positive. Sound On Sound says it makes monitoring much more predictable and replicable across rooms, delamar finds the calibrated response close to neutral whatever the room, and owners — from a Korean producer in a small, heavily damped room to a composer mixing Atmos on seven of them — say their mixes hold up elsewhere. A film editor on Reddit gets them within broadcast flatness standards with GLM.

“I mix everything from stereo music to TV to theatrical, and mixes ALWAYS translate accurately.”

Fred Story, Gearspace (owner, Atmos room with seven 8330As, four 8320As and a 7360A)

“If you record or mix in different rooms often, I think that the Genelec 8320A or 8330A, together with their included accessories and GLM 2.0 software, would make your monitoring very much more predictable and replicable.”

Bob Thomas, Sound On Sound

“이정도만 되어도 룸 특성을 이해하고 있다면 다른 곳에서 전혀 다른 결과물을 듣는 것 같은 경우는 매우 드물었습니다.”

pkjohn, Tistory blog (Korean: “even this much is enough — if you understand your room, it was very rare to hear a completely different result elsewhere”; owner, small treated room)

Low, with faint hiss up close. delamar finds the noise floor negligible — just audible at 1 m with ears pricked, and only in silence. A Gearspace owner hears a faint tweeter hiss that is hardly audible at 1 m and noticeable at 50 cm in a quiet room at night, which his dealer called normal; another owner says every Genelec he has owned, 8330As included, does the same.

“Im üblichen Abstand von einem Meter ist mit gespitzten Ohren noch subtil zu hören, aber eben nur im Leerlauf bzw. bei Spielpausen in Aufnahmen.”

Felix Baarß, delamar (German: “at the usual distance of one metre it is still subtly audible with pricked ears, but only at idle or in pauses in recordings”)

“1m away, hardly hearable, 50cm closer, 'yes' human can hear (but nothing bothering-kinda level)”

Method Man, Gearspace (owner, small room)

GLM is the reason to buy it. Sound On Sound, Audio Media International, delamar, Bonedo and MusicRadar all rate the automatic calibration highly — level and delay alignment, subwoofer phase matching and several stored profiles for different seats or rooms — and Audio Science Review calls the improvement dramatic. Owners add the AES/EBU digital input (13th Note heard a little more clarity that way) and how easily a Genelec sub integrates. The caveats: the GLM kit is an extra purchase today, the correction works mainly in the bass and cannot fill nulls, there is no TRS jack, and an ASR owner thinks the built-in correction is overrated when you can EQ on the computer.

“The improvement is dramatic and you would be silly for not using it if you have a Genelec SAM speaker.”

Audio Science Review (amirm, GLM review measured on the 8330A)

“GLM should not be optional. It is such a massive difference.”

soundmage, r/genelec (owner)

“First, we wish Genelec would include a TRS jack input as well as the XLR.”

Jon Musgrave, MusicRadar

Sources split on running everything through software. Sound On Sound, Audio Media International, delamar and Wolves Unite found setup and calibration fast and simple — delamar had the whole system running in three minutes. Others trip over the lack of any rear-panel control: input sensitivity, filters and auto-standby need GLM and its kit, an owner without the kit found the digital input deafeningly loud with no way to turn the speakers down, Bonedo and MusicRadar miss hardware switches and an analogue-style volume control, and owners report GLM refusing to run on a new macOS or a calibration that hung.

The cabinet itself is universally praised — MusicRadar calls the build first-class, delamar and Bonedo flawless, and owners describe the cast-aluminium boxes and metal grilles as nearly indestructible. The split is quality control: Nuyes found one of two new 2023 units still carrying the ~2 kHz response rise Audio Science Review measured, while the other matched Genelec's data, and a Thomann buyer had one monitor distorting below 115 Hz out of the box (replaced at once).

Generally rated well, with a real counter-argument. Audio Media International calls the price-to-performance exemplary, 13th Note "ridiculously good value", Sound On Sound found nothing as complete at the price, and owners on Thomann, Gearspace and ASR call it a sound investment. The dissent: an analog 8030C plus your own room EQ (REW, Sonarworks, Dirac) costs much less and gets close, owners on ASR and Reddit don't think the GLM premium is worth it, and a film editor would recommend Yamaha HS8s for casual listening. US prices have climbed to about $1,125 each before the GLM kit, far above European pricing.

“the price-to-performance ratio and flexibility of this little system is exemplary”

Nigel Palmer, Audio Media International (8330A pair with the 7350A sub, 2015 UK pricing)

“Calibration makes a huge difference, but it's not worth paying 1000$ extra for it.”

geo2160, r/genelec (on the 8330A versus the 8030 plus a separate calibration kit)

“They provide about 90% of the sonic accuracy and just as big of a soundstage for 15% the cost.”
