Hello to everybody,

I am going to get a mint matched pair of Altec 604E so I am looking for a proper enclosure for this glorious driver. I read a lot about "original" boxes like 612 or 620 or DIY wonderful enclosures but in almost all cases the project requires a huge amount of internal volume.

I live in a small lodging so I can't afford a big speaker cabinet thus I need your skilled help to get the better performances even in a small volume enclosure.

First of all my available space would be in a "bookshelf-like" location namely on the upper shelf of a living room furniture. The possible maximum space is 34" length X 12" depth while the height is free even if less than the length.

I read also that this driver may accomplish some new trends like the Open Baffle design with a lot of natural fresh musical reproduction even if perhaps with some bass lacking... This Open Baffle theory could be a good approach for me because I could consider a frontal baffle with the 604 fitted to it and all around a frame less than 12" to allow rear flow of waves against the wall. Actually the enclosure would be an open baffle C shaped (front baffle with flour wings). By the way the cabinet location on the shelf is in front of the wall.
The other solution may be a classic bass-reflex but I guess that in this way I will have some problem with very limited bass response.
The allowed dimension are to be intended external so it must be considered for internal volume calculation the ?? wood thickness.
Please may you help me in suggesting the right design for these Altec?s.

I appreciate your contribution!

Guglielmo
