I'm looking to convert an old bass reflex speaker to an infinite baffle box. The simplest way is for me to affix a new front baffle to it but if possible I'd like to be able to remove the new baffle. Would a screw on panel be sufficiently air tight? Could I use a gasket or similar to achieve air tight status? Thanks
Screw-on panel is ok, with some hot glue around the hole just before placing the panel on.
A thin gasket would be fine instead of the glue.

I remember some ported speakers came with dense foam "plugs" for the ports to convert to infinite baffle if the room or speaker placement made it a better option.
Someone on this site must have had experience at doing this. Hopefully someone could advise if this is an option. Certainly much easier than fitting an over baffle.

The KEF LS50, for example. The foam plug is rather dense but soft.
Try it and see, adjusting the depth of the plug..

The way I read it, the OP may be going to remove the old baffle and replace it with a new one (removeable and sealed with something like self-adhesive foam draught excluder strip).
He may even be introducing different (sizes of) drivers to the enclosure, requiring different cut outs.
Have you anything to add thejt?

If I understand correctly, you want to convert vented (bass reflex) speaker to sealed one? Is that correct?
IMHO you might (will) not like the results. The drivers, crossover and size of box play huge role in the SQ of the speaker. Your bass reflex speaker was never designed to be sealed. Among other things, you will loose a lot of bass.
If you are talking about infinite baffle, that is something very different. Typically the term "infinite baffle" is used for speaker (usually subwoofer(s)) installed in a huge enclosure (almost infinite for all practical purposes) usually adjoining room, attic, large closet etc.
thank you for all the feedback everyone. By infinite baffle i am referring to a sealed box design. The box I managed to find is an old Altec design used for a 604 dual coax as bass reflex. I am looking to convert it to a mid bass sealed box for a 15" coral as part of a two way horn set up.
This is very much on the money! I was looking to retain as much of the original baffle as possible as additional mass and as a stiffener. THe new baffle would screw onto the existing one and i will adhere a gasket onto the old baffle as a seal.
