* - We think that a simple number does not reflect the actual worth and potential of this kind of speaker. The simple frequency extension cannot transmit You the emotion that this loudspeaker is able to transfer You.

Note:

In our workshop we can offer true-wood veneers.
Wood is a natural product and depending on several factors might have different color and structure. Color and structure variations of the surface are not to be considered flaws.
