so i got a decent offer on my 15s and im not sure if i should sell them as i will want to buy something that would give the same or more output

i was looking at yuli's Digital Design 9510F that hes got for sale but ive never really seen a DD in action before

id like to keep the new sub(s)/box under $400

 

opps forgot to mention i have 2 15" RF punch HX2s wiht a hifonics BXi1606D amp

 

DD's are incredible!!!
