I have nearly finished building my first sub. It has a 12" downfiring driver (200W) in a 47L sealed box. The room I will be using it in has a tiled floor.
Originally I planned on making the feet 3.5" long from a piece of 1" dowel attached to each corner of the box. I would then place the sub on a square of carpet to stop it damaging the tiles.
Is this the best way to build the feet? Having spent so long on this already, I don't want to stuff it up at the last minute!
Any help will be much appreciated.
Thanks
James

You might go just a bit higher on the legs. At least for my woofers, I needed to get tham about 5-6" off the floor to smooth out the bass. If your cabinets are heavy enough, the actual legs won't be too critical; with my woofers (about 150 pounds), we could hear (and measure) no difference between spiked feet and heavy-duty casters.
NB: I have a concrete slab floor; YMMV with other types.

I have just build a downfiring sub, into a sortof coffee table.. about 160 ltr. It is a rectangular box, so i got some 3x3 wood and chopped it to make 4 inch legs. Then i bolted + glued these to the bottom at each corner.. flush. The router is now run up the corners to create a 45 degree angle on the corners. looks quite good i think. just needs a nice finish on it and all the 'business' end is pointing downwards so therefore no need for grills etc
I thought downfiring added this protection as well. An exception if you have young kids with building blocks (or other < 3 - 4" toys). Some of those blocks / toys could work their way under the sub and sit neatly under the surround (esp. if your driver is not recessed and flush mounted, or worse protrudes). this would no doubt cause problems with uneven voice coil travel, causing grating. Less of an issue if the dustcup hits the block.
In any case you'd soon pick that up (hopefully before any damage is done).

Coke cans... I stand my 50lt 10inch subwoofer cube on Coke cans.. 🙂 or bottles.. but cans are more stable... 😀 lol
Cheap But Good.
I have used (still do) car engine valve springs as mounting feet, and find the result to be better than hard mounting in all applications tried so far.
Efficiency increases, and the sound is free-er and more musical ime.
These are free from your local engine shop/automotive wrecker.
