I have 3.5s and Velodyne ULD 15 sub that work well. Innersound amp. started and finished for a while. Love the sound. Make sure they are insured for replacement cost for shipping errors. It happened to me when I purchased mint condition and the shipping co dropped them. 3 months later I have to re breakin factory reconditioned 3.5s that are basicly new. Love em and I only tell my new puppy that!
