These are an LDSG recommended driver using a combo paper/tpx cone. They are exceptionally well balanced and clear sounding drivers. I wanted to use these but I am now using passives and due to the 8 ohms impedance, must use a 4 ohm driver with my passives. I would rank these somewhere right below the Seas Excel driver from a clarity/detail standpoint, but above most other drivers I have heard including the CA18RNX's. The RNX's will give a lot more midbass, but midrange with these is smoother and cleaner. It has a very nice transparency that may have something to do with it's low inductance (.6mh which is lower than the Seas Excel W18 driver). Brand new and ready to go. Priced at $100 SHIPPED. I have photos for those that wish to see (they have a see-through cone that is really awesome).
