Audiodave you would be well-served to have your builders build a box with screws and another with brad nails. Use the same wood and same glue. You will see that neither fail under the pressures that a subwoofer can produce. If you have all of your joints together, what would cause a board flex and crack/break the glue joint? NOTHING. If your glue cracks or breaks from stress, that screw is just going to come out of the wood as would a nail. They are only useful until the glue dries. We are not trying to contain a bomb blast. We are creating pressures that this material can handle with ease. Glue is more than adequate for a standard box build. Once you see how much faster, and how STRONG boxes with brad nails are, you will increase your profitability in your shop. You are wasting man hours on nothing. I'm doing 150's with a brad-nailed box. It's holding (2) DD9515g's on 3500 clamped watts. If your box has leaks or a lot of flex, you cannot achieve this spl. Get off your high horse. You can maintain your ego. You don't have to admit it in here, but to help your business you need to compare and find out how wrong you really are.
