A18S + AVAC4 Caster kit

This package pairs the Avante Audio A18S 18-inch active subwoofer with the AVAC4 caster kit, turning a 73 lb cabinet into something one person can roll across a venue floor instead of carrying. The A18S itself runs a Class-D amplifier at 500W RMS and 1600W peak, covering 35Hz to 150Hz with a 127dB peak output, and built-in DSP with an LCD screen puts EQ presets on the cabinet for quick tuning between rooms. Combo XLR/quarter-inch inputs and balanced XLR outputs make it simple to connect a mixer or link additional cabinets, and the ground-stack pole mount supports a top speaker directly above it. The AVAC4 caster kit adds four heavy-duty wheels built with precision ball bearings for quiet, low-effort rolling, along with a locking brake on each caster to keep the subwoofer securely in place once it's positioned. Installation is designed to be quick and straightforward, bolting directly onto the A18S cabinet without modification. For mobile DJs and venues that load in and out of the same space regularly, rolling the subwoofer into place cuts down on the physical strain of repeated lifting, especially when paired with a second unit or additional gear on the same trip.
