From AT Professional, the GROUNDSWELL is a SUB LOW dual 18″ 6000 Watt box for full sounding bottom end.
Not usually at this high power range, we have managed to get the boys to make us up some amazing full sounding SUB LOW boxes made in our typical “old school” fully phat sound…. These guys boast an amazing note and levels of up to 134dB @ 25-160Hz – that’s just crazy.
These are not like a front loaded Sub Enclosure which give the kick in the chest style of sub, but we can totally understand how they come up with the name for these boxes…such a low note the literally shakes the ground beneath you.WOW!!
And to boot, did we mention they are locally made in Australia.
