If you are looking for a combination of precision, quality and power for your main speakers in the studio, you can not go wrong with the SC4 series. The SC407 is characterized by a very powerful amplifier range, with an amplifier per driver. Large woofers duplicate all frequencies up to a certain crossover frequency. The mid-range woofer resumes from there. This means that even all four-way speakers are symmetrical, as the woofers do not provide different frequency bands, but essentially duplicate the low frequencies with the utmost precision. The result is an incredible bass reproduction, a very linear response and lots of power to shake your main control room. The elegant gray panel in the center of the speaker accommodates not only the midrange and the AMT tweeter but can also be rotated so that the speaker is positioned vertically or horizontally.
