thebuckaman Posted April 25, 2015 Report Posted April 25, 2015 I just ordered two of the new Stereo Integrity MAG v3 12s. I am putting them in an expedition powered for the time by a Sound stream Tarantula nano 1200 (may upgrade this). I cant decide on box size or tune. I am thinking 3.5 cubes to 31hz. Port size? Thanks. Also, does anyone know if these are dual voice coil? If so, what the impedance is of each coil?

Triticum Agricolam Posted April 25, 2015 Report Posted April 25, 2015 Looks they are single voice coil (4 ohm) and have an Le of 2.4 mH. Should be really nice subs.

thebuckaman Posted May 1, 2015 Author Report Posted May 1, 2015 Just heard back from Nick. They are dual 2 ohm coils. I am selling the TN1.1200 and just bought a Synergy Audio WFO 15.1 to power these.
Joe X Posted May 2, 2015 Report Posted May 2, 2015 You would need an amp that sources 2K either at 0.5 ohm or 2 ohm.
