Question about BP Power

Recommended Posts

I have decided to buy the Fi Q10. It was a tough decision between that and the IDMax 10, I actually decided on the Fi because my custom box is very small, I hope it will give me great performance in this small box (also it fits, the mounting depth on the IDMax is a little too long). Anyway, my question is: should I get the BP power option if I am NOT going to install the sub inverted. Someone on the CAF forum said I would have to install it inverted to get the benefit of the BP option. I am running an Orion 1200D amp, I will get the dual 2 and run the amp at 1 ohm, would be about 1200 watts max (I may not set the gains that high). Should I get the BP power option or not?

:wtf: Where do these people come up with this off the wall stuff :worthless::bsflag:

I realize that some of the stuff in forums is way inaccurate and off-the-wall, but your reply is not helpful at all. How about an intelligent, informed answer to my question? Thanks.

The BP option option adds a machined aluminum compression plug to the pole which helps channel all of the air under the dustcap around the coil for better cooling. To aid with this increased airflow we also add 6 axial cooling channels in the top plate. Along with increased thermal capacity comes the addition of an extra spider and a changed spider pack for a little extra mechanical ability.

All of these new features increase power handling from 200-500 Watts depending on the application.

There is a little spec change on the drivers as we are adding a little more suspension stiffness (although we are swapping stiff spiders out for more soft ones too). The subs stay a little closer to their original suspension values and have a slightly increased qts, fs, and reduced vas. Not too much of an issue and I have found it to be beneficial in mst bassrace setups.

Now this is not something for everyone and I dont think that most people need to add it. But we are getting more and more bassrace applications where being able to stack more power to ge the sub to its linear limits for a specific application requires more than the rated RMS power (often quite a bit more) and this option allows you to push things a little harder for some applications. If you are looking for a SQ setup or just a clean daily setup within the normal limits of the subs... then there is no point.

Would I recommend it to someone with 1200W in a daily driver? I doubt it as it really wouldnt be needed and the extra 200W really isnt an issue. Its the guys that are trying to stack on 1800W and push them as hard as possible for 30 seconds (or try to all day) while voltage starts to drop and things start to get ugly towards the end.

Hope that helps

And yes whoever said that in the CA forums should be immediately placed on your IGNORE list

I need to bump this ancient thread. (better then making a new one)

I have a paper in 3D modeling to make anything I want. And I started to draw one of my Fi Q 18" subwoofer, I have drawn almost anything. But I have one problem, and that's I'm not willing to open the motor to take a look at the BP power option. I have searched around on forums any where and I can't find a picture of a motor with the BP power option. So until now I have drawn a motor after a couple of pictures of one Q motor without BP. But I would like the draw it correctly with the BP option.

So I have read the description above, but, I have some problems understanding it, is the plug something like a traffic cone on top of the pole so that it directs the air flow between the voice coil and pole? And I have no idea how the 6 axial cooling channels in the top plate looks like...

If someone has a picture of a Q motor with the BP option or maybe if someone could explain how it looks on the pictures below, then it would really help me out:

Here are a couple other pictures if someone is interested (note: I took some liberties, as not all parts were possible to measure, and all are high res):
