Really cool pair of speaker drivers that I have never got around to building a proper set of cabinets for. They are a pair of very high end 18 Sound 12" midwoofers where the dust caps were removed and an Infinity car audio (small profile) was installed, then a new dust cap put on. Wires then run out the back. The main drivers are 18 Sound 12NDA520 12" Neodymium Mid-Bass Speaker 450Watt 8-Ohm. Current price is around $400 CAD per driver. These come with custom crossovers, so all you need is a pair of speaker cabs, or make an OB speaker with a sub. https://vipproaudio.com/2x-18-sound-12nda520-12-neodymium-mid-bass-speaker-450w-8-ohm-mid-low-transducer/
