mr.clean Posted August 6, 2010 Report Posted August 6, 2010 I'm lookin to buy a BTL 12 and trying to decide the options to go with... i know i want the dual 2 ohm, the daily option, and the universal option... HiXmCoil: This coil is simply much longer than the normal dual 1ohm or dual 2ohm flatwire coils and allows for more xmax. If you are using this in a daily scenario we suggest that you choose this option, especially in the 15 and 18 inch models. Inner Heat Sink: Its a machined aluminum ring in the gap that lowers the voicecoils inductance (allowing it to play up higher and have a little better overall transient response). It also reduces the volume inside the magnet gap of the motor increasing air speed with the cooling as well as allowing the coil to kick off heat to a more receptive thermal mass rather than magnets. here are the two things i dont fully understand... if someone could explain these two in depth it would help... im going to be running 2000 rms on the sub but mayb more later. it will be a daily sub and mayb a competition or two. so what would you suggest option wise?
