Linear, or mechanical? 3" P2P linear would give them ~40mm Xmax.

Anyways; Tumult had an Xmax of 34mm. 13W7 was dumaxed at 34mm Xmax IIRC.

The JL gotham/phantom(modified W7) sub can do 4" p2p, Jl engineers say it in a vid anyways.

haha agreed. I've noticed people failing miserably at humor in the last couple days, if you want to be funny, BE ORIGINAL! The same old stuff is played out and never was funny to begin with. .

What do you mean by "finished"? The Parthenon has the most linear excursion of any other sub out there at 80mm one way.

I think he meant production, but from reading the site a while back, theyre built once ordered so technically your right, just that no ones actually seen it finished, just that motor vid.

Supa C posts and says.... FUNKY PUPS!!!. 10 Inches XMAX!!

It's not linear ... do you honestly think that, with a few modifications, you can increase the W7's already astounding Xmax by 70% ? I don't think so ... Also, considering JL Audio always has and probably always will rate Xmax by the one-way voice coil overhand method (Voice coil height minus top plate thickness, divided by 2), it would require a complete redesign of the driver, not just a few modifications ...I don't see linear anywhere in there ... do you ? ... The W7 is capable of roughly that amount of excursion as well ...

Uhm, no

The LAMARE has the most X max of any sub that ive seen.

According to Adire, the parthenon isnt a sub //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif

Funny how the one guy calls it a driver then says box.

Plenty of marketing crap in that video

Sure, every company does it(marketing) one way or another, but i think JL is professional enoughnot to lie about what the sub can do. It might not be perfectly linear, but if its capable of moving that 4" p2p(in the real world).
