It’s easier to set-up the Logitech Z623 since it is only a 2.1 set.
The most obvious difference between the two is that the Logitech Z623 is a 2.1 speaker set, while the Logitech Z506 is a 5.1 system. Setting up the Logitech Z623 is easier since you only have to worry about two speakers, while the Z506 will involve a lot of planning and furniture rearrangement if you want to take full advantage of its true 5.1 surround sound.
Size-wise, the Logitech Z623 subwoofer is bigger than the Logitech Z506 sub. The dimensions for the Logitech Z632 subwoofer is 11.2 x 12.0 x 10.5 inches, while the Logitech Z506 subwoofer measures 6.7 x 8.3 x 10.3 inches. Inside the Logitech Z623 subwoofer enclosure is a 7-inch driver, while the Logitech Z506 subwoofer comes with a 6.5-inch driver.
As for their satellite speakers, they have the same elliptical shape, except for the center channel speaker of the Logitech Z506, which has a horizontal orientation. On the Logitech Z623, the satellite speakers come with a single driver for the mids and highs. In contrast, the Logitech Z506 satellite speakers comes with a mid range driver and a tweeter.
Setting up the front and center speakers of the Logitech Z506 is straightforward, since you only need to place them on your desk. Also, the center speaker comes with a folding mechanism that allows you to put it on top of your monitor. However, the rear speakers can pose issues since you’ll need to place them at your back or at the sides. Needless to say, you’ll need to do some planning if you want to get the best out of the Logitech Z506.
Controls and Connections
The Logitech Z623 has more inputs and it comes with better controls.
On the Logitech Z623, all the controls are accessible on the right satellite speaker, including the power button, bass volume and main volume. This makes it easier to adjust everything since the right speaker will usually be placed within arms reach. On the Logitech Z506, the power switch and the main volume controls are also on the right satellite speaker. However, to adjust the bass volume, you’ll need to reach down to where your subwoofer is placed to do so. This is far from ideal, so in this area, the Logitech Z623 wins.
Both speakers are designed for use with a PC, but you can also connect other devices like DAPs (digital audio players), game consoles and more. The Logitech Z623 has two 3.5mm audio ports and a stereo RCA connection, so you can connect up to three devices. Meanwhile, the Logitech Z506 has three 3.5mm connectors for analog 5.1 and a stereo RCA connection as well. You can only connect two devices to the Logitech Z506 simultaneously. Both speakers have headphone outs on their right satellite.
The Logitech Z623 satellite speakers come with 2 meter cables, which are just long enough to place them on your desk. As for the Logitech Z506, the left and right front speakers also have 2 meter cables, while the center speaker has a 2.7 meter cable. Since the rear speakers should be placed at the sides or ideally, at your back, they come with 5 meter cables.
Both speaker sets are able to output excellent sound for their price.
While these two speaker systems won’t sound as good as standalone bookshelf and tower speakers, for their price, they are excellent. Both speakers can output room-filling sound, with the Logitech Z623 having a slight advantage due to its higher peak and continuous power rating.
The Logitech Z623 subwoofer can reach lower frequencies than the Z506 subwoofer—35 Hz to be exact. In comparison, the Logitech Z506 subwoofer can only go down to 40 Hz. The difference might be small, but it is still there and it is noticeable. The Logitech Z623 can also output more power, which means that it won’t distort even at higher volumes.
When it comes to gaming or watching movies with 5.1 audio on a PC, the Logitech Z506 can definitely provide a better experience since it outputs true 5.1 sound. There are no simulated surround or virtualizations, so it is really immersive. When listening to music, both are great, but the Logitech Z623 has the edge since stereo is all you need for music.
You can connect several devices to both speakers and on the Logitech Z623, there are no issues since everything will be outputted in stereo. On the Logitech Z506, however, any device that you connect via RCA will be virtualized on all speakers, since the RCA connection only accepts stereo. This means that the speaker will not output true 5.1 and as a consequence, the sound quality might not be the best.
Both are excellent performers for their price.
The Logitech Z623 is a great 2.1 speaker system especially if you are on a budget. It outputs excellent sound and it has several input connections for use with other devices. If you want a hassle free 2.1 speaker set at an affordable price, the Logitech Z623 is a great choice.
The Logitech Z506 is also a good speaker set as it offers true 5.1 surround sound at an affordable price. However, it only offers true 5.1 when connected to a PC and it only offers virtual surround when connected to other devices via RCA. If you are going to connect it to a PC exclusively, then it is one of the best entry level 5.1 speakers that you can buy.
Yes, it is an affordable 2.1 system that outputs great sound. For those on a budget, the Logitech Z623 is a great option.
Yes, you can connect any game console to the Logitech Z623 either via RCA or 3.5mm cables.
No, it only has analog inputs—5.1 analog and stereo RCA.
For gaming and movies, 5.1 is definitely better than 2.1 since it can provide a more immersive listening experience. However, a 5.1 setup also comes with a lot of headache since you’ll have to place the speakers in optimal spots to get the best experience. In addition, you will have to deal with a lot of cables and wires, so it might not be the cleanest setup. A 2.1 setup is preferred by a lot of people because it is easier to set up.
