[QUOTE="Phil Graham, post: 59881, member: 430"] Re: B&C Sub designs Kip, Loren, Yes to what Loren says about driver SD vs port area. It should be mentioned that flared porting is its own can of worms, and doesn't change the fundamental Reynolds number issues. It can help shape the vortex effects the port ends. Certain gradual flare profiles popular with the hifi crowd can be detrimental to port behavior at the higher Re in professional audio. I think the phrase used was "an honest look at the simulations" followed by an immediate caveat that no one would build an 80% of SD port. [/QUOTE]
