I just recieved 2 Fi btl n2 15's in the mail (dual 2 ohm) and when I hook my DMM up to each coil it reads 2.3 ohms??? both coils on both subs are the same but reading 2.2-2.3 ohms. Why is this and is that normal? as i read that fi dual 2 should be 1.4 each not 2.3...... i dont want to have to send them back as it took a month and a half to get them here . My dmm was set to ohms at 200 as thats as low as it can go.
