all neo subs that come to yalls mind...

The shocker neo is actually heat treated and would be very hard to heat past the point of strength loss.

so if they lose stength when hot, do they lose power handling when hot also?

Heat treating affects tensile strength. Ive never heard of it affecting a neo magnet's characteristics regarding heat. Care to elaborate? Sounds bogus to me. If you could simply heat treat neo magnets to 'fix' their biggest flaw, Id think more companies would be using them.

Power handling is loosely based on two things, thermal failure or machanical. Machanical means the suspension or motor/vc bottoms out. Thermal failure means more current passes through the voice coil than the speaker can dissipate the heat from, thus allowing the vc to melt and short out. Neither of these situations occur when a neo magnet motor heats up. What happens is it looses BL, motor strength.

No, power handling is a function of the voice coil, not of the motor.

Gti's are a ferrite motor...i've got a couple of them //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Really really cool design

Heat treating will affect magnetic strength too, but generally in a negative way, as it causes the magnetic domains to randomize again, hence why ALL magnetic material loses magnetic strength when heated, not just neo. I also believe that a metal magnetized at high heat may be able to hold more magnetism as it is heated up again due to the hysteresis effect.

Are GTIs a split VC design?

When I took a trip to Vegas in May I asked scott at Fi why he didn't make neo subs and he said heat was the issue. I believe he says the motor won't goto 100% after heat loss so Vegas=hot and they work in a small storage unit so no fi neos

Generally we are talking multiple hundreds of degrees here, nothing that happens anywhere on this planet naturally outside of a volcano or the Earths core, the heat in LV is NOT hot enough to demagnetize a neo motor.

split coil with one coil in the topplate and the other in the back plate, with the polarity reversed...

differential drive is what they call it... probably one of the best sub designs there is...

GTi's are bad *** subs. They dont get enough credit around here. And they are relatively cheap.

I think they lost some respect when the new ones came out with chrome dust caps and basket accents...I thought my Mk1's were sweet looking, not so much the Mk2's.

I love the look of the MK2, but shit is that a deep basket.

Im not a fan of their aesthetics either, but their performance more than makes up for it.

More people should run down-firing setups anyway.
