How to install a port?

andrewmc · 3rd March 2007, 05:20 PM

'm going to install the port tube that came with the kit this weekend. It's the CSS flared port - looks a lot like this:

I'm a little confused by the flanges at the back of the port. The flanges are 3/4" long - same as the wall material that I'm using. Should I cut the hole to the OD of the flange, or to the OD of the pipe, and then cut slots into the wood for the flanges to seat?

I would just notch the wood around the ribs while allowing the port to still press fit into the box. You should also used a sealant like silicone to make sure there is no air leaks.

The flanges are to apply spring tension so I think you should make a hole to fit around them and press it in like that... I would be carefull with silicone as paint will never grip well to any residue of silicone on the wood... maybe 'sicaflex' or just superglue would work better...

All I do is cut a hole slightly smaller than the diameter of the flanges and push the port home. Stays in nicely.

We use these ports when we do cabinets for Bob at CSS.
Best thing to do
CUT off the fins period.If not you only have less than 3/16" of mounting area to pit the ports on.
This is OK but not the best.We cut the fins off these when we have to use them and then just drill a 2" hole and the ports are a nice tight fit.

Thanks everyone. I cut a 2" hole and then cut slots for the fins. Everything fits well, but I don't think it was worth it. Next time I would cut the fins off for sure.

Thanks for all your advice!

I know it's too late now, but...

How about running the ports inside-out? Installed from the inside of the cabinets, with the flared end inside the cab. You could run a round-over router bit around the inside of the tube after you glue it into the baffle if you wanted to maintain a flare.

It's important to make that straight edge a flared one like Max suggest's

High outputs will reduce air turbulant noise flowing in/out of this area as much as possible.
