  1. I've built subs out of cheaper hardwood ply and MDF before. The cheaper ply works but is more vulnerable to damage than BB ply, this can to an extent be made up for by rounding (and filling if there are voids) the corners and using a tough coating. MDF is horrible to work with, heavy and vulnerable to damage at any exposed edge. I would use cheaper ply rather than MDF. I don't use screws I use a brad nail gun and glue, this way you can build a cab very quickly!

  2. BB holds screws better as well. In general I avoid MDF or HDF when possible, especially on larger cab sizes. For things like small monitors and car subs it isn't a bad choice to save some money.

  3. No, but not because of the different impedances. The biggest issue is that the high frequency section is a lot more efficient than the low frequency section and needs attenuation to play at the right level. Another issue is that you really need a high low pass filter for the mid or else it will make a mess of your upper mid response. And you probably want to cross closer to 1500 Hz. More generally to get good sound quality you really need a crossover that's custom designed for the combination of drivers, which for your case is actually 3 different drivers. In your first post, you said

  4. I will agree to pretty much everywhere here. BB is nice for things that get big, even if you don't move it much. When you do need to move it (and you will) you won't regret the BB.

  5. Moving up and down stairs to roundover, sand, fill any tear out, sand and paint was a bit of a chore, requiring assistance of a hand cart, ratchet straps and a strong volunteer. Also, the number of good weather days were limited, coupled with working away from home a lot meant that I could not spend as much time working on these as I would have liked at a time. Second one is partially assembled.

  6. No offense to RF as they do have some sharp guys but the whole, driver optimized for sealed / vented / BP and don't use it in another alignment, is for the most part antiquated thinking from back before modern signal processing. There are drivers that are better suited to some jobs than others make no mistake, but this is not one of those. Usually the reason you will hear that drivers are not suited for sealed is the qts is too low (IOW too efficient) and without EQ it will be bass shy because the top end gains sensitivity quickly and overpowers the low end without EQ. In this case RF is assum

  7. I thought you were doing a really nice build but that 85 degree port is unacceptable and you probably need to start over. Just kidding. I think it looks great. Great job and you should be very happy.
