[QUOTE="adulbrich, post: 8332634, member: 661255"] If you have any corrections, please let me know. I just thought I'd share this with other people. I never knew it made a difference. Also, bump if you found it helpful! Apparently, wiring in parallel instead of series is better (even to get same impedance). Cliff notes for people who are annoyed by Showtime SPL, or are too lazy to watch the video: Amp: 5000w RMS (50 amps and 100 volts)- Example A) dual .5 coil wired in series to 1 ohm: each coil gets 50 amps and 50 volts Example B) dual 2 coil wired in parallel to 1 ohm: each coil gets 25 amps and 100 volts Both receive an equal amount of wattage. In example A, each coil receives more current, which builds more heat. The higher heat reduces the efficiency of the voice coil. Faraday's law of induction also states that inductance in a series circuit is summed together. In parallel, it does not change. High amperage and low voltage will not make a s large of an electromagnetic field. A higher voltage will make the field larger. He gained a few tenths in SPL by simply changing coil configuration.
