okay on the fully loaded 18 inch btl what would be:

peak to peak xmax

rms power handling

weight

and what would be a good amp to run four of them or amps. i was lookin at 2 jbl crown amps the 8k watt ones @4 ohms would that be good. or should i do one per sub. well what would the experts do. i listen to rap and thats what will be played loud and long. so what amps would you put on them-brand,series,and wattage

All the BTL specs are posted clearly on their website. As for your amp question that is an easy one, get one that will do the power you need.

well the specs on their page are befor the upgrades isnt that why theres a * after certain specs. i mean the xmax is different after you add the high xmax coil right or the mounting depth would change after you add a third magnet right. you know just like the price changes after its fully loaded so should some key specs. im sure they dont list the upgraded specs with the flat price

anyone, anyone. thats why i need the specs so i can get an amp that will do it right. i also figure that it will handle more power after cooling upgrade otherwise whats the point

oh another question what exactly are the cones made of. oh and are they pretty linear at high excursion levels. im just curious ive never heard or seen one in real life

Fully loaded the xmax if I'm not mistaken goes up to around 26mm. With the power handling I really don't know but, doesn't really matter. Even if you didn't get the cooling option it would still do 2000-4000 all day, can be even more if your careful. The cooling option is mainly, just to give them a longer life for daily use.

None of his questions really matter. It is a burp sub meant to get super loud which it will and take a crap ton of power doing it.
