Hi,
Maybe someone knows. I’m mounting a horn on top of a bass reflex cabinet. I need the wire from the horn to run in the box via a hole. Is there some kind of small metal grommet I can use to accomplish? I’ve seen some backs of systems and there’s some kind of small grommet but all I can find is shelf pin grommets or fabric ones (the rest are large for like desks and power cables).
I’m using 1” solid wood so I need a finished look.
Thanks in advance for your help.

Hi maLx.
I suppose the woofer box needs to be air-tight ?
Why don't you use a connector instead ? You could use an XLR-3 male to chassis female, omitting one pin, or even better, a speakon connector, more bulky but since it will be in the back of the box...
Cheers.

I don't believe the box should be airtight but the grommet may make a soft interface so the wire doesn't break in the hole.
Hi, it does not need to be airtight since the box is a bass reflect box but should be as tight as possible. I’m trying to avoid using a connector. Looking more at something I can feed the wire through a small hole.
what size wire? jacketed or single strand?
could be as simple as an appropriate size rubber or plastic washer held in place with some latex chalking so the hole to accommodate the wire doesn't get a chance to whistle or fart with pressure that should be going out the bass ports you lovingly tuned.

If you don't anticipate moving the wire after it's installed, you could just use RTV to seal the wire in the drilled hole.

Banana jacks are sometimes an elegant solution for that. And yes, even a reflex box should be made as non-leaky as possible because leaks cause non-ideal behaviour of the reflex box.

I often just pack the hole with polyurethane foam once the wires are in place.
These grommets are often used for water tube, fuel line, and electrical cable penetrations through plywood bulkheads in boats... They might be what you are looking for...

Jim, that’s great and close to what I was looking for. I’m trying to find a metal option. Just something neat to clean up the hole I can then seal from the inside.
or, you could size up a piece of plastic tubing. Whatever diameter you need and drill a snug hole for it.
Once everything is hooked up, would you need something that could be disconnected again?
Speakon has all black connectors that don't scream "I'M A PA COMPONENT".

Agreed, but it is at least under some control by the builder compared to whistling and fartig leaks.

Banana plugs are a thing from the past and should be avoided at all cost if possible.
I would looking in chandelier stores.
They usually have grommets where the supply cable enters.
There are also chassis rubber grommets.

They are an old archaic design that were not originally designed for high current applications, they are somewhat unreliable, and as mentioned above can lead to shorts. I won't use anything but Speakons.
