yes in a large box u can get away with that but if its like a 2.5cuft box tuned 35 it will end up being around 38" long ...might have to do a side firing port with something that long ...i will make do with my lil 4" aero yes ....
no i think it's a bit smaller, a few mills off if i remember correctly, it's been a while since i've used the rrr ports, i getting used to just ordering precision ports from parts express now
tried all those already, the thing is when you pressing at the open end to expand it, further up the line (about an inch or two) bending up & getting wavy / wrinkled as it is also soft.
as you go deeper dosent the front not get wider? I reach about 1.5 inches deep & the wrinkles start. the opening has to be forced open & apparently requires more force to open than it takes to cause the waves further up.
