IOS 18A SUB

IOS 18A SUB is the larger variant of the IOS series bandpass subwoofer — an 18" plywood enclosure, German Class D amplifier with switch-mode power supply and 1000 W RMS. It reaches lower than the 15" model (bandwidth 35–150 Hz vs. 40–150 Hz) and achieves a higher level of 133 dB, making it the better choice where bass depth matters at large outdoor venues.

The LCD display with multi-point DSP and delay adjustment up to 100 ms simplifies phase alignment with the top section in a multi-way system. The 18" woofer with a 3" voice coil (85 oz) for continuous high-load operation. Delivery from Poland, VAT invoice.
