Short version: I'm thinking that the 1.5 cube after sub displacement that the sub is in now is good but the port area is too small and tuned too high.
I have been building some small little DIY studio monitor type things for my computer and even with crappy used plywood that was left by the previous home owners, I managed to do a decent job. Not the best looking but turned out much better than I thought it would. So I figure I could try using MDF and building a sub box.
Right now the sub is in a 1.75 32hz box that was built for a 12w3. It does good but I can hear air being forced out of near the gasket on lower hz (28-32 I think)
I tried a box that was about 2.2 cubes with huge port and I was finally able to get voltage drop on about 30hz-ish - not only that, but there was no sound of air being forced out of the gasket area (I'm assuming this is because there was adequate port area that allows the air to properly escape)
Should I just keep the same design and just make the port area bigger and tune lower? I was thinking 26hz. Emphasis on low end response and stability.
Right now I peak at 41 but I hate anything above 36hz.
Any suggestions appreciated.
