Guitars into speakers

I have some quality Vifa mid-range drivers and tweeters that need a new home.  I already have a number of bookshelf speakers so have been thinking of making something a little different.

The spec sheet for the driver provides a recommendation for the ideal enclosure volume (3–10L sealed) so I'll be starting with that as a first step.  However, I like tight sound and am not too fussed with pushing out a lot of bass (and if later that is desired there's always the option of adding in a port or even a subwoofer to the system) so I'll be looking at making a test housing to pick a desirable sound profile.

The plan is to make a box with a sliding baffle so I can determine the desired volume.  I'll put plans for this up over time.    

The next step will be to knock up a basic cross-over circuit so the speaker can be tested in the temporary housing and the best volume determined.  That will provide the necessary dimensional requirements for the internal volume of the guitar body.
