While midrange and high frequencies are naturally more directional, low frequencies tend to radiate in all directions. Excessive bass levels can be quite the problem on and behind the stage. The more serious issue, though, is that promoters are increasingly making demands to limit the sound distribution range. And there is no alternative to cardioid technology when it comes to meeting specifications for low-range frequencies. With its hardware appointments and filter sets, the 18” LINEAR 7 subwoofer provides a fast, easy way to configure effective cardioid setups.
