Hello tomorrow i got 2 of these altec drivers
and i will use them in a good sounding speaker
i was thinking about an open baffle in the first place.
because i hear already Altec 605 in an open baffle a few days ago and it sounds wonderful!
but i think the 604 is a little different from the 605 is an open baffle usable with this driver?
the man who has the 605 say it is no problem
but what are other good housing options for this 604?
Based purely on aesthetics I love the 606.
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk
Here is one of many. This is the Altec 620 cabinet. It is often used with the 604.
Freak out...Far out...In out....
that is one
there is also a 612 cabinet a little smaller
but i didn't see them much in an open baffle.
Hello, I also just got some 604s and need a cabinet. I also was interested in the open baffle, and put together a trial baffle based on information on the web. The mids and highs were very good, but there was great roll off of the bass such that there basically was no bass. I gather a much bigger baffle will help with that, but I don't have that much space (and my wife is not that understanding).
After more research, it seems the best cabinet is a 9cu ft enclosure, such as in the diagram provided in an earlier post. Also of consideration is whether to use a port slot (tune to 40Hz) or a port tube (tune to 28Hz) - I am going to try the port tube. This is my first venture into speaker building, so I disavow any knowledge about anything.... merely relating my experience with open baffle and what I have read.

a Karlson K15 (developed in 1951 - marketed in 1952) is a good cabinet for 604. The rear chamber is only about 3.6 cubic feet, and system tuning in the 40's, so it won't go"low" but it will provide articulate bass.
