5" Round Ports- Where to Buy?

[Blues Cat]

Does anyone know where I can get a 5" ID round port?

I've done a pretty exhaustive search but can only find 4" or 6", but nothing in between it seems.

ABS pipe from Home Depot?

It's going on a drumhead so I need the front lip. I think abs would be too heavy for a drum head.

brother Blues cat ,---you want a 5"diameter port --port tube for a speaker box ? right? ----I have used plastic pipe for bass cab ports ---excellent ------I suggest you tune the port by the length inserted in cab --the tube when it hits the depth that wakes the cabinet up --depends on the free-air resonance of speakers ,and the desired program material the cabinets being tuned for ---get matching pipe plugs -in case you want to go sealed on some other set-up. hardware store/plumbing supply ----p
