how do these subs compare for the money?

Yes, thats exactly what I was trying to convey

but also that any subwoofer with the same displacement as the other (actual tested parameters, NOT manufacturers specifications) has the potentiality to achieve the same SPL figures. It is just a matter of exploiting its traits in a different manner.

The Fi Q15 will get just as loud as a Mag 15, each given their desired boxes and the power necessary to reach xmax (not exceeding thermal limits of the VC) will get just as loud as the other and can sound just as good at the same time. The Mag is often portrayed as an amazing SQL driver (which is true), but that is also capable of considerable SPL figures that are larger than drivers in its same category...which is an exaggeration. The Mag cannot defy physics. It has just been exploited (very well i mind you), by some excellent SPL builders just as the Type-R was.

umm...while all of you are argueing could someone let me know if running 2500watts to an 18in BTL is alright? Don't know too much about subwoofers and xmax and all that stuff, but I have an Orion 2500D and im wanting a BTL.

On the website, to the right of the subwoofers, it has a few different options. Do you all recommend spending the extra $20-$30 for each option? ie. cooling, magnet, etc.

I don't see how we can argue the "sound" of the drivers without having seen BL, Cms, or Inductance curves (unless they are available, in which case, link me up).

If you are going to make an argument for technical data holding true to the sound heard, you had better have these available to demonstrate the similarities; BL and Cms compression accounts for around 90% of all distortion.

yes spend the extra doh, and im sure the BTL can handle the 2500 watts daily wit the gains set right
