How far you mic an instrument, and how it sounds on play back I feel depends on the play back system.  The better the playback system the better distant mic-ing sounds, but on low fi stuff close micing sounds much better.  Don't even think of asking my why, but I know it is true.  When I go to listen something, I always take a recording that I know most of the instruments are recorded from a distance.  Piano and drums especially take on a spacial property.  Most would feel these are not as good of recordings, but on a good systems they blow all that close mic'd stuff away.  Of course the type of mic used makes a large difference in all of this as well.

Wax, that is a little over simplified but we will let you slide this time.

Oh, it's the old resonance magnifaction through a multi-phasic conductance medium theorem, is it. This argument does have some merit, as it is well known. If the forcing frequency is equal to the natural frequency the magnifacation factor can be quite large. But the fundamental is still a coefficient of viscous damping and is not the same as the natural frequency, this of course is a result free vibrations. On the other hand, it's possible the oscillations could be under-damped which of course means there will be a diminishing amplitude of the sound wave at that locus and therefore the resultant noted increase is the result of psycho-acoustic aromatic hydra-tetra-cannibinols that the government has surreptitiously added to the varnish. In any event it's still fluid dynamics..."a less slick surface!!!" They just don't teach techno-babble like they used to..Sigh.

Trust me David, I know my vibrator's and fluid dynamics.

Let's try and keep things clean Wax...thanks

There for a minute I thought Ms Wax may have inhaled a bit too much fumes as well.

didnt i mention something about mic tecniques and dumping in digital bullthingy ages ago?

In the end it doesn't suprise me that mismatched drivers lend a more natural sound in this design.  Maybe Steve should PLAN on having 2 different drivers in the final design, if that's what sounds best!

Got a question about those wood lenses.  When you notched the back of the plywood to allow for the bend did you cut through all but the last layer of ply?  It sure looks like it from the pictues!  Is plywood usually consistent enough or did you have to make a couple goes at it to get it just right?

I do plan to have two different drivers in the final design.  It is just working way to well.  It makes it possible to keep this a two-way design.  

As for the wood horns, yes, I cut to the last layer.  The two I built were the first trys.  They are not perfect.  However I know now how to design the jig to make it less painful to build.






Here is a picture of the new 15 inch drivers I got.  I'll take a pic this weekend of the cabinets with the drivers installed.
