Veneering a Small Floorstander??

KenCalgary · 28th November 2009, 04:44 PM

Please excuse me if this question has been answered though I couldn't find any. I am thinking of building a pair of 38litre floorstanders (I will soon decide on the configuration of drivers and therefore sealed or ported) and will apply veneer to either MDF or Baltic Birch plywood.

Veneer suppliers (e.g. Oakwood) say that you must veneer both sides of a board so that it doesn't warp due to uneven drying. So my question to those of you who have veneered speaker cabinets is: Did you veneer the inside faces of the box? if so, how? If not, did you have any problems with warping?

Thanks, Ken.

Ken,

(from Calgary?)

Veneering both sides is good practise if the have a flat panel, and will stiffen a speaker box a bit. We use baltic birch for our cabinets and don't often veneer the inside of the panels (which has to be done pre-assembly. In a well braced loudspeaker, veneering the inside of plywood is a lot of effort for very little benefit.

If the box is built and then veneered, then there is next to no chance of warping.
If you veneer one side of a stand-alone piece of plywood or MDF it will most likely cup or bend.

Thank you, everyone. I feel much more confident now about building a pair of speaker boxes.
