Goldwood Speaker Box Bass Air Ports 2 Speaker Port Tubes Black (PT-308-2)

Just what they are supposed to be. Fit well to the holes that I had created BEFORE I even looked for them. Very pleased with the sound reinforcement.

To those that are curious as to what size hole you need to cut, the thickness of the material, at the ribbed portions, is approx. 1.5mm, that's 1/16th of an inch to my Imperial brothers. So unless you have a 80mm hole saw, 3.125", you might have to sand\rasp a little after a 3" bore, I used a router. I would assume this is true for all the Goldwood ports, but cant say for certain. DO NOT FORCE. They are plastic, they will break. If you make them a little too big, that's what wood glue\chaulk\RTV silicone is for, happy tuning.

Bout my own box for some 8s wish I would of went bigger on ports but these do wht there made for

The mug arrived quickly-a huge plus as it was a Christmas gift. The personalized logo wasn't centered. Not that big of a problem. The workmanship aside from the centering is great.

Nice tight fit, longer tube gave speakers better sound

Works great for my sound system on the bike

Product is flimsy, the rings at the end were shipped partially broken, does the job, just don't expect something to show off to the neighbors.

Fit great just make the hole a little smaller

bon produit .. bien adapté.

Fabrication fragile pour le prix demandé
