So far: Looking like 5" and up will require too large of Vb or Vc for desktop use. Vas is only considered as a rough indicator of the enclosure size. Xmax ~ one indicator of low frequency capabilities.

We have used these drivers and put them into (as small as is the smallest we have put them in):

Thanx Dave,

I can load them into BassBox6 and play with Vb and Fb or Closed Vc values. Smaller drivers will tend to beam less HF. Not sure how much whizzer cones, phase plugs, cone contours affect HF dispersion.

If one can get away without whizzers or phase plugs then one is ahead AFAIC.

Be careful with the modelling… it is way easier to come up with an ugly alignment than a good one. Sealed is much more tolerant but almost all of these need the extra output from a vent to do bass.

When modeling there are a lot of things to consider past the frequency response graph. Test boxes, FR and Z measurements, etc.

I want low level detail foremost, bass is important also, but planning on a modest near field sub to augment. Don't want listening fatigue in the mids,highs.

A6.2 or A5.2 then. A6 will get you a bit more bottom.
