@ Orange: do you mean you just modify stock?
@ laatsch55: I'm sure xover tweeks and the right amplification go a long way. I doubt that was the case in any of the demo's I've had. While I don't find preference, it doesn't mean I don't like them at all (horn)
@Larry: I glad you're interested in these. I actually fell in love with the sound of the morel duets, which use the exact driver complement, although my woofers are 4ohm which also came with a slightly higher efficiency rating- cant remember 100%.
As much as I liked the sound of the duets, I feel that the morel 6 inch driver is really just a big midrange driver. The duets preformed beautifully but fortunately could bottom out easily in the TL cabinet. Lowish sensitivity and shallow xmax. Seems like recommendations put this in a sealed enclosure, which makes sense to me. However I noticed kits were pretty much unheard of for this and I think the above says why.
One company that I thought had and interesting approach to these was eggelston in the early (first?) Andra. The morel 6's were used as midranges only,and the bass was a dynaudio 12 ( x2 iso config). This made sense to me based on 1: My experience with the power handling in lower frequencies and 2: I had the driver tested by a reliable loudspeaker engineer.
When I had the driver tested, I was really looking to confirm if my basic instrument/PC setup was working properly, which as it turned out was. What I wasn't expecting was the recommended 9 liter sealed enclosure. What I didn't understand was that it wasn't going to give the driver good sound in a two way, so when I did make those cabinets, I was having a rough time with the sound.
That being said, the 9 liter suggestion was probably spot on as a midrange . And would i have to say that tests involving drums that could kill normal drivers never sounded more amazing, just no deep bass.
So here is where I want to go... I would like to add a third driver to these and make a tower. If I go for a pair of bass drivers from madisound I can get a complete xover design from them. That would Likely be a pair of SB acoustics 12's.
In the mean time i'll think on the two way, very kind of you to offer the help. Do you think 4k is a bit high for this MW164? Seems like it would create a bit of a dip in the off axis.
Here's a TL design I found.

Here are the old test boxes, 1 inch MDF, braced. Front baffle is 2 inches thick.
