Source for metal speaker ports

Hi 🙂

Does anyone know where I could find metal speaker ports?

I want to give a bit of trendy look to my bookshelf speakers with metal speaker ports.

Thanks,
James

Metal electrical conduit. It normally comes in 10 ft. lengths.

Jaycar has em,

Probably too big for your application, but most car audio places sell bass ports too.

zBuff,

I already know that Jaycar has plastic speaker ports but I am specifically looking for metal speaker ports.

I am thinking of chrome plating the plastic ports as the last resort, but I really like to use real metal ports if I could find any.

Hot water pipes? Or use a plastic one as a model for sand casting and get someone to melt the metal.

Look for local CNC companies. The cheapest method is if you have access to CAD, you can design them and have the CNC computer mill them. If you can design some common stock, it would be cheaper then milling from a solid chuck of metal.

you dont specify if you want straight tubing or flared.

for straight pipe, call a car exhaust shop. you can get mild steel, aluminum, or stainless steel. the latter will polish up nicely and remain so for a long time.

mcmaster.com also sells it.

A metal port sounds conter productive to me. Wouldn't the metal ring like a bell and become too good of a sound/vibration conductor? If it becomes a problem, you could line it with a rubber like compound or glue a thin layer of foam to hidden surfaces...

Yes, the metal would ring like a bell. Even heavy pipes. But I like the sand casting idea because one could make it as thick as you like.

Don't forget the possibility of using fired clay. Highly malleable and has resonance properties more like concrete. Although I might consider mixing in a bit of powdered pvc or plastic to make it a bit less vulnerable to impact cracking.
