Celestion S80 SubwooferS80 is an elegant active Celestion subwoofer, which replaced S8. A rigid body is made of MDF. A heavy sub is installed on cone-type legs. The speaker with eight-inch diffuser made of especially finished cellulose and a pair of bass-reflex ports are located at the bottom. The system has wide functional possibilities. There are low and high amplitude inputs and outputs, a smooth signal phase control - the latter is rarely seen in even more expensive low-frequency systems. Auto turn on and off of the sub is provided. S80 do not try to reproduce a deep bass. We can suggest that the developers, limiting the range of tasks of the subwoofer, focused on the increasing of the quality of their solution. Due to this we immediately wanted to try the system in 2.1 musical system. It turned out to be hard to establish an optimal ration of bandwidth and amplification level. But in the end we got the sound with clear and even transparent upper bass, and this bass not only strengthened the image tonally, but significantly enriched it dynamically - with all the resulting "spatial consequences". The bass is well-balanced and this is important. Of course, you shouldn't turn the regulation handle of amplification and bandwidth to the max, although exactly then low-frequency additive is mostly noticeable. At the fully open band it is hard to exclude the inevitable coloring in mid-high bass (extra "fluffiness"). As expected, the sub works with shelf speaker systems much more effective than with floor ones. In the theatre the system definitely signals about its presence, although the lack of low-frequency power is noticeable in a large room. S80 is good for a delicate low-frequency expansion of the potential of small shelf systems in small rooms. The sub is quite universal in these conditions. There is the sense to correct signal for satellites by a built-in filter of high frequencies. ![]() |
