Biggest thing I have yet to do is an impedance sweep to determine cab tune. Throw a little smoothing at it and the green curve nearly becomes a straight line. Ok thanks a lot.

So, would it be okay to say: But im not sure how this goes with actual box building. If im wrong someone please point me in the right direction. GlassWolf Platinum Member Username: How important is the h: I read on some other forums that you shouldnt exceed a 9: I just wanted to know if anyone has experienced this problem. The internal height of the box im designing has to be at least Here is what I came up with: Im designing this box for a single IDQ 12 v3 tuned to 28 Hz.
Unfortunatly the ratio of h: That would also make the end of the port about 2 inches from the right wall, That brings up another few questions. How many turns in a port is too many? Does having turns in the port effect sound quality negatively? And are U-shaped bends a bad idea? Back to the original question though, I want to get some opinions on my current box design, is that port width too small? Should I just scrap this design and start over? Sorry about all the questions but I have never designed a ported box before and I'm just looking to learn from the fine members of this board.
CanaanWhite Bronze Member Username: Since I got no answers on my other questions, I just assumed 2 turns is okay. Heres what I came up with: Ever see how many turns some more complex enclosures have, like transmission lines?

Based on searching around, I have seen some comments like "keep it to a minimum of 2" height" or "don't go lower than an 8: While WinISD models air speed based on cross-sectional area only, so it predicts the same results for a circle as a paper thick port so long as they have the same area, I suspect that this is missing something big.
It has been shown that port chuffing is more of a problem with higher tunings and higher air velocity, so that is not really what I am looking for here, just the missing piece of the puzzle that makes slot ports perform worse than round ports if they get too narrow.
Thanks in advance for your replies. Originally Posted by LTD02 the missing piece of the puzzle that makes slot ports perform worse than round ports if they get too narrow.

The fifth largest of all the lakes in Minnesota, Lake Vermilion stretches about 40 miles from end-to-end and covers nearly 40, acres. Its two main basins, widely known as the Cook End west and Tower End east are separated by Oak Narrows, and each features abundant structure and cover where gamefish can spawn, feed and grow.
More than visible islands are interspersed with countless rocky offshore reefs and shoals that attract prey fish and predators alike. In short, Lake Vermilion is a one-in-a-million fishing destination that every angler should experience at least once, according to competitive fisherman and Team Northland Member Jamie Lindseth. Muskies, too, are a prized quarry, and the status of their population offers any savvy angler a decent shot at catching a plus incher.
Lake Vermilion is rich in structure, so while the areas Lindseth points out here are good starting spots, he recommends using them as a guide to identify other fish-holding areas as well. Depending on the season and the day, you may not need to venture farther than these marked areas, but you can expand opportunities by expanding your range.
During the fall, narrows and pinch points become hotspots for walleyes because the predators are keyed to ambush spots where they can attack schools of baitfish in a confined area. Snap-jig the combo while moving the boat slowly along with the electric motor. Farther west along the southern shoreline, try the mouth of Everett Bay as well as the waters around Jack Rabbit Island, using the tactics already mentioned.
Walleyes will be anywhere they can find a dependable food supply. Fall is also prime time for big muskies. Lindseth recommends fishing the string of main-basin reefs and shoals stretching from Potato Island to the northeast, using crankbaits, bucktails and large soft-plastics.
