Grunge......I await your verdict. If you do it, please post your thoughts on the matter. I'd love to hear your findings.
It was a 3 1/2 inch port that I melted through the 20" two ply head.
If you use a reinforcement ring it will probably be more durable.
It was just one of those "What If" moments. I don't think that it would work well with a single ply head. I've had them split at the port when on the reso side of the bass.
