In this review, we will be comparing G Two and G One, two Powered Bookshelf speakers by Genelec. Being Powered speakers, they both have built-in amplifiers so you don't need an external power amp or an integrated amp to power them.
Let's have a brief look at the main features
of Genelec G Two and Genelec G One first before getting into our more
detailed comparison.

G Two features a 0.75" Dome Tweeter and 1 x 4.1" Cone Woofer with a Crossover frequency at 3000Hz. On the other hand, the G One features a 0.75" Dome Tweeter and 1 x 3" Cone Woofer with a Crossover frequency at 3000Hz.
Frequency Response
G Two has a frequency range of 62-20k Hz whereas G One has a frequency range of 74-20k Hz. With a minimum frequency of 62Hz, the G Two can go significantly deeper on the low side and provide stronger bass compared to the G One's min frequency of 74Hz.
The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Bookshelf class in our database.
Low Frequency
Bookshelf Speakers
Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.
Cabinet Type and Port Position
Both G Two and G One have rear firing ports. Rear ported speakers generally need more room between the backside of the speaker and the wall compared to sealed and front/bottom ported speakers. Placing the speakers too close to the walls may cause the bass to sound boomy.
If you are limited in space and can't get the speakers away from the backwall, check our Speakers with Front Firing Ports page.
Physical Specs
The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare Genelec G Two's and Genelec G One's external dimensions. Genelec G Two has external dimensions of 242 x 151 x 142 mm (9.5 x 5.9 x 5.6) whereas Genelec G One has external dimensions of 195 x 121 x 115 mm (7.1 x 4.8 x 4.5).
Genelec G Two is clearly the larger of the two speakers. Its body is 30mm wider, 47mm taller and 27mm deeper than Genelec G One.
Below you can see the front view size comparison of Genelec G Two and Genelec G One in scale.

Base Surface Area Comparison
Base surface area of a loudspeaker may become a determining factor when the space in your room or desk is limited.
The base surface area of the Genelec G Two is approximately 214.4cm2 / 33.2inch2 and base area of the Genelec G One is approximately 139.2cm2 / 21.6inch2. The G Two requires 54% more surface area than the G One which gives it a small disadvantage on placement in tight spaces.
Here is another comparison that shows both speakers on a BDI Octave Media Cabinet, next to a standard size amplifier and turntable in scale:

Weight Comparison The weight of a loudspeaker can become an important factor if you need to move and reposition the unit often. Weight of a speaker can also "sometimes" be an indicator of the rigidity of the enclosure and the quality of the internal components used. The Genelec G Two weighs 3.20kg / 7lbs and the Genelec G One weighs 1.70kg / 3.7lbs. This makes the G Two 88% heavier than the G One.
Here is a comparison of how G Two and G One's weights compare with the average, max and min weights in Powered Bookshelf class.

Siblings in Genelec's G series, so they share a family sound. It comes down to size, output and price.
| Area | Better | Why |
|---|
| Bass | A | Genelec G Two digs deeper - 62Hz against 74Hz. |
| Built-in power | A | Genelec G Two has the bigger amplifier (100W vs 50W RMS). |
| Size | depends | Genelec G One is easier to place; Genelec G Two is bigger, which usually goes with fuller bass. Your room decides. |
| Price | B | Genelec G One is cheaper - $700 against $1,050, about 33% less. |
A Genelec G Two B Genelec G One
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.
Which should you choose?
The usual trade-off: Genelec G Two measures better, Genelec G One costs about about 50% more% less. Whether that gap is worth the money is the call only you can make - and in a normal room it is often smaller than the numbers suggest. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 74Hz anyway, which makes the cheaper Genelec G One much easier to justify. In a large or open-plan room, Genelec G Two has the cabinet volume to fill it more easily; in a small room, near a wall or at desk distance, Genelec G One is the easier speaker to get right.
And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
