I bought these about a month ago but they are not efficient enough to pair with my Fostex drivers. Used for about 30 minutes - never soldered. GR site claims efficiency of 95 dB, Bohlender Graebener site says 90 - I feel the latter is correct. These have a rubber cup on one side to make them drectional - held with silicone - remove for dipole. Shipping is $5.35 in CONUS.
