[QUOTE="Moble Enclosurs, post: 7492653, member: 634917"] It looks like a great design! Without actually figuring for the response, one cannot comment on it's performance though. BUT, knowing a lot about loading factors, this end of the port area, much like a tapped area, will not add much to the response due to the sudden expansion from the constant port area. if anything, that part will increase the output only at higher frequencies, likely out of the efficient range of the drivers response. BUT the great thing is, it will likely not hurt the response either. So, this is one of the few types of ideas that will work for appearance and formal physicality as well, so it does not appear so "basic" in appearance. As far as it becoming a 6th, technically everything loaded into a vehicle with windows will become a straight or quasi BP acoustically. So, technically yes. And as far as phase cancellation.......again, not something visible. It would have to be calculated. But a lot of times with phasing issues, you can point out some physical qualities that reoccur. In this design, so much is going on it would be tough to tell, and anyone that says there is/isn't cancellation would be lucky to guess right or wrong. You have a compression area, a constant port, and end expansion, and a tapp going on all at the same time. Could become very efficient, but again, since you have it modeled, you might as well calculate it as see what it can do.
