From the press release:

The Leisure Monitor Universal Satellite is designed to provide an acoustically homogeneous theater (of 5 or more VM1s plus a subwoofer). The body is made of a highly viscous polymer. The front panel with two heads is closed with a non-removable metal grille. Includes steel stand and bracket for wall mounting; they are inserted into one of the two slots on the rear panel — vertical or horizontal (depending on the desired orientation of the speaker) — and fixed with a screw (the key is included). The bracket device allows you to rotate the monitor around the mounting axis. For some money, you can also purchase a floor stand.
The speaker in both vertical and horizontal positions provides exceptionally high spatial homogeneity of the sound field, which contributes to the naturalization of many spatial effects and their quality is weakly dependent on the listening position. Juicy, as if emphatically embossed sounds actor's speech. In moderate volume modes, the VM1 accurately tracks the dynamic relief of the recording. Of course, the advantages of VM1 as a centre channel speakers will be most fully revealed in the environment of "twins", but in almost any application, the participation of a subwoofer (better than a proprietary one) is desirable. In this case, it is advisable to transfer the receiver to the small speaker mode. The speaker has good musical inclinations, most adequate to chamber forms.
