I bought a group of speakers which had twin horns. the smaller ones had the Frazier ( Atlas) drivers with Frazier # 333-300. I get no sound. I've disassembled them and checked the voice coils in their magnets directly with a feed from my stereo and get nothing. Anyone know what might be wrong? Blown voice coil? Visually it appears intact and not broken. Can I test the coil with a meter? Mike
