Frequently asked questions
Can I use the AC118S by itself for full-range sound?
No. The AC118S is a subwoofer only, covering 32–40 Hz and below. It must be paired with a full-range system (like mains or monitors) to reproduce midrange and treble.
Is the AC566 powerful enough for live performance venues without a subwoofer?
Yes, the AC566 delivers 122 dB SPL (128 dB peak) and covers the full 60 Hz–20 kHz range, making it suitable for live gigs and studio work. However, venues requiring sub-bass below 60 Hz would benefit from adding a subwoofer like the AC118S.
Which is easier to transport and set up?
The AC566 is lighter and more compact (680 × 420 × 445 mm), requiring only one unit for full-range coverage. The AC118S (32.3 kg) is heavier but still portable; it requires a separate full-range speaker, so total setup is more complex.
What's the key frequency-response difference?
The AC118S focuses on sub-bass (32–40 Hz and below) and requires mains for midrange and treble. The AC566 spans the full audible spectrum (60 Hz–20 kHz) in a single enclosure.
