I am looking into upgrading my substage, so I think I will sell my current one.
Basically, XXX18s in 7ft3 boxes tuned to 17Hz in Mahogany veneer. These also come with a pair of Dayton HPSA1000 rack-mount version sub amps (they do 115/230V).
This will only be sold in Germany, or as far as someone is willing to come and pick these up I can't ship these for obvious reasons.
$3000usd.
