Genelec 8000 vs 8300 vs The Ones: Which Series, and Where the GLM Kit Is

Genelec makes three families of monitors that look like the same box wearing three price tags. Mixing them up is like assuming every Fender is the same Fender with a different number on the headstock. The short version: the 8000 series is the classic analogue monitor with no calibration, the 8300 series is the same two-way idea with DSP and GLM calibration, and The Ones are three-way coaxial monitors. And the thing people ask about most: yes, some 8300 bundles ship with the GLM Kit in the box.

Three families on the maker's numbers

Start with a table, because photos of these monitors mislead more than the spec sheets do. Data from Genelec's pages, prices per speaker, as of today.

Notice the 8030C and 8330A share the same maximum SPL (104 dB) and differ by 2 Hz at the bottom. For the extra €182 you are not buying volume. You are buying what the manufacturer describes as room compensation as part of SAM: a digital AES/EBU input, a ±1.5 dB tolerance instead of ±2 dB, and correction in GLM. Whether that is worth it depends on whether your room needs it. In an untreated space it is a real argument; in a well-treated one, a smaller one.

Where the GLM Kit is, and why bundles put it in the box

SAM calibration needs the GLM software and a measurement kit. The manufacturer sells the kit separately, so if you buy monitors alone you add the GLM Kit at €301. For the 8320A the manufacturer names only the GLM Calibration Kit; for the 8330A and 8340A the 9320A controller is also an option. That matters when you plan the budget.

That is why the stereo 8300 bundles are worth a look: everything comes in one box. Genelec Stereo 8320APM bundle, €1499: a pair of 8320A with the GLM Kit and a wired volume controller. A small monitor (100 dB, 3.2 kg, down to 55 Hz) for the desk. Genelec 8330AP bundle, €1895: a pair of 8330A with the GLM Kit and the 9310BM controller. Check the sum of the parts on the day you buy: we do not promise a saving, because part and bundle prices can drift apart, but a bundle has one benefit you cannot price, which is that nobody forgets the measurement microphone.

Which series for whom

The 8000 series when you want a simple monitor and do not plan to calibrate. If the room is treated and the budget is up to about €1200 a pair, a pair of 8030C is an honest starting point. Note that Genelec marks the 8040B and 8050B as discontinued, so look at models the manufacturer still makes.

The 8300 series when you want the same size class with calibration. If you need more at the bottom, the Genelec 7350A (€1259) is the subwoofer the manufacturer matches in its selection table to the 8030 and 8330.

The Ones when you want the three-way coaxial layout and more headroom. The choice between the four models is covered separately: Genelec 8331A vs 8341A vs 8351B. It also helps to read how to place studio monitors, because no series replaces placement.

Straight answers

Choose the series by how much calibration you actually need, not by which one has the biggest number in its name. Genelec is consistent about this: the bigger the number, the bigger the box, and the bigger the box, the more often the question is where it goes.
