Hi.
I'm embarking on a speaker project that specifies 46mm ID ports, and I have to admit, I'm having trouble finding any.
I'm in Australia, and I'll be down the hardware and plumbing supplies soon with my calipers, but I haven't been able to find anything matching online yet.
Any ideas?
Thanks,
Michael

Just recalculate the port diameter and length to suit what you can get. If you put the existing numbers in WinISD, play with the Vb, port dia, port length, you can then find the Fb (box tuning frequency).
Just change the port dia to what you can get, and the new length will appear.
Use something like WinISD or what ever you have.

This has been a non-issue for me from the time I built my first BR enclosure. See here for a description of what I do. You may find Australia a tough place for odd-diameter ducts, but I'm in India, and I guess it's just as hard here.maf_au said:I'm embarking on a speaker project that specifies 46mm ID ports, and I have to admit, I'm having trouble finding any.
Re: Re: Bass Reflex Port: 46mm where to buy?
Actually what is supposed to be 2 inch PVC pipes in India are perfectly 46 mm in diameter..
That's what i have used in my active speakers.
