5 cu ft subwoofers with the SoundSplinter 15" drivers and 4- AE 15" flat passive radiators in each cabinet. I have them stacked or co-located to act as a single subwoofer. These subs model out to 13 hz at 1000 watts. Each subwoofer has a 1450 watt pro amplifier with the Reckhorn B-1 bass management system to control all frequency duties.
