You can buy the BTL with a pole chamfer on the top of the pole. Maybe if you ask Scott nicely he will machine a pole vent for you but it is not currently an option on that driver.

Have you read Dr. Klippel's paper? I wish I still had the chat log where Nick Morgan (of Fi) said point blank that the reason the Q has a pole vent is to keep the BL (and specifically the Qes) appropriate for the intent of the driver. I'm sure you can email Scott and ask him if you'd like to. No matter what I say you won't agree, so you're probably better off asking him directly.

Both you and Prolifick (whatever) could benefit from listening to what Neil mentions here. The *only* thing that I have seen that could have *any* real benefit to cooling a motor through a vented pole is what JL did with their patent. Otherwise, it is a waste. Vented poling and perceived cooling is a concept that marketing has taken and run away with.

If you wish to passively cool the coil via air velocity, the best way to do it is through the back plate within the coil *gap*. And even then, it is minimal.

And if plugging a driver into a wall socket is your way of testing 'technology', then I suggest you stop your testing methods. Go to school and learn the basics first, then you can go from there.

Best regards,
Mark

Maybe we can get a special one for you that says " I tried" or "Participant" It seems like the competitors with know-it-all-ism such as the sundown pals in Edmonton can never really put up decent numbers for some reason

Example....

Sundown pal's explain, complain and whine about how good the sundown amps are compared to other amps.... They come to a show with a hatchback car, and get beat in street B by .1 with someone who has a crossfire BMF-1000 and a deck that didnt have a remote.


So seeing as how both of you also suffer from know-it-all-ism I hope you can back up your sweet car audio education with some good numbers on the term lab.


Um... I'm not sure what to say.

How old are you?

what he is trying to say is that you two are like the people who play flight simulator alot and think they can fly a plane or the people who play counterstrike a lot and think they know everything about warfare.

OW! OW! MY BUM! IT HURTS! OW!

You really told me off there didn't you Prolifuk? I'm sure after you hit the Post button a euphoric feeling came over you didn't it? I guess its par for the course now that I am expected to go to my corner and sit there and sulk about how butthurt I am...

Ain't gonna happen. Truth is, prototypes have circulated for months and have fallen into hands more experienced at SPL comps than you or I (oops, I'm sorry, but there actually is someone out there more proficient at this than you).

Results from different folks were favourable, and I was satisfied enough with what we accomplished to roll it out. Is it the end-all-beat-all of drivers? Heck no. Never said it was, or would be.

Did you notice what was said? 'I was satisfied'... yup, me. Not you. I could care less what you think or say. Got that? Ok. Good.

Ah, now I don't feel so butthurt anymore....
