[Boatanchors] Speaker Cabinets

[Brad Pioveson W9FX]

Hi, all.  Seems that I spend more time talking about boatanchors these days 
than I do working with (or, on) boatanchors.  That brings me to my current 
query.  My hamfest buddy and I were discussing the 'great sound' provided by 
NC300's and other receivers of that era, and, I made the comment that I 
wondered how much of the great sound we remember was due to the active 
devices, i.e., the tubes, of those receivers and how much could be 
attributed to the large speaker cabinets we used back in 'the day.'  Which, 
of course, got me to thinking...wonder how much today's rigs could benefit 
from something along the lines of a Hallicrafters R48 or similar?

So...not wishing to reinvent the wheel, I am on a quest for speaker cabinet 
design info.  The woodworking is not a problem - I have the tools and 
skills.  But, what design parameters have y'all already considered and 
incorporated in your own 'perfect' speaker?  What worked - what didn't? 
What size speaker(s)?

I'd appreciate any input any of you can provide.  Please respond off the 
reflector, directly to my email address.  If there's any interest, I'll 
summarize the info and post a summary to the reflector.
