Port Tube Triangular is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from Added BoostMy cabinet sound flat and dull. I put the port tubes in the bottom corners and it gave it the needed boost. There is not much lip on them so the cut needs to be cut as close as possible. I cut a pattern to fit the port and used it as a stencil for the hole. It cost more to ship than to buy but they were the only items I ordered.

Rated 4 out of 5 by from Good port for Creative IdeaUsed this port in a custom sub enclosure in trunk of car . Kind of difficult to cut proper opening for port since its a rounded triangle, thats sides bow and flare out to opening. Wish Parts express offered lengthing tube for this product, I just bought 2 and cut one up. Good sound, minor port noise due to small flared edge at mouth of port. Overall works well, more critical listeners would choose a different product.

Port Tube Triangular

How do you cut out the hole angles for a tight fit?

Asked by: G. G.
Make a template and transfer the template to the cabinet. Then drill a few pilot holes and use a power jig saw to slowly make the cuts. That's the down and dirty method. Those with a wood shop would use a router. Both will give good results with patience. And remember - measure twice, cut once... So true - I've made more than one mistake !!!

How well will this wrap around a 8 inch woofer and what size does it compare to a round port?

Asked by: Superglide
designed to make a narrow cabinet for pro use with horn tweeter and utilize the frontal driver mounting ergonomics and cost... the size [volume] is all that matters ... it works well with an 8 but you may need two depending on your port volume tuning in relation to box size
