? I was looking at the hdc3 18's but they need 12 cubes per pair. that will be pushing it.
He's right the HDC318's will work fine in 4.5 cubes, tune around 35-36I have found that most of the large 18s that are designed for car audio work in 4-5 cubes. And I do know that hdc18s will work that small. Although you will want to start tuning at 36hz and work your way up. They don't have the low end extension tuned at 40 in such a small box.
