I picked up 2 new Carvin PS-158 speakers in a trade with the intention of making a pair of cheap 115's or possibly a sealed 215. Problem is, I cant find specs for them to design an enclosure with. The sticker on the magnet looks like an Eminence sticker, but I'm not certain. Has any one used these speakers in sealed cabs with good results? And if so, what dimensions were the cabs?
