The LINEAR 7 118 Sub A subwoofer is a true powerhouse. Its direct-radiating bass-reflex construction allows for compact dimensions, and weighing in at just 42 kilograms, it is extremely easy to transport. A powerful punch, precise playback, and impressive low-frequency performance make this active bass the ideal complement to the LINEAR 7 satellites.
What’s more, it meets all the requirements for quickly and easily implementing effective cardioid setups, both mechanically and with the available filter sets. Thanks to its stereo preamplifier, it is also ideal for use in 2.1 systems.

Cardioid pattern for real-world applications
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.
