(an assembly table makes it easier)
Build a speaker box easier and faster by first making a pressing table. This table can serve as an assembly table, gluing surface, clamping surface and temporary workspace all in one.
The best news is that it cost less than $200.00 to build it. And if you’re building really large speakers it will be quite useful.
Build a speaker box that’s better… Start with the right tools.
Its not really necessary for small speaker jobs, but you may still want a flat surface even for smaller projects.
What it does:
– it lets you press the speaker cabinet panels down from the top.
– works like a large vice to squeeze the parts together while gluing.
This speaker assembly table will make your speaker build easier.
Use the best speaker building tools possible to complete your project perfectly the first time.

How to Build it!
Take a 4×8’ sheet of MDF and place a 2”x4” frame under it also bracing ever 8” on center from front to back. Set the whole thing on some decent saw horses or a solid cross braced bass that you make.
Attach two boards on each short end (4ft) of the table making them cross 24 inches above the table surface. You could join them together at an intersecting angle and running some long screws into them for strength. Spread a set of sandwiched 2×4”s or 2×6”s the long length of the table 24 inches from the surface. Bolt these to the cross braced uprights.
The end result is a horizontal arm that travels the center of the table 24 inches above the surface of the table. It is mounted to the frame of the table so that you can use screw jacks (found at a building supply store to apply pressure down toward the table.)
This allows the use of screw jacks (mounted on the floating arm) to push down against the speaker from above the table.
The table obviously holds the speaker in place while it does this providing maximum pressure. Use blocks and boards to spread out the pressure from the screw jacks.
• Use wax paper to keep your tooling from sticking to the speaker cabinet.
The arms must be firmly fastened to the frame of the table and the table must be able to withstand the force of a screw jack pushing down on it. It basically works as a temporary press.
You use it to press the parts of the speaker together from the top while also using conventional screw clamps from the sides.
The table must be absolutely flat and rigid, take the time to build it very strong. But it does not have to look pretty.
This is a type of press for speaker brackets mounting.
Useful for assembly of speakers and other large panels
This press would be useful for gluing any large panels together. Large speakers are unique because you need to use uniform pressure. Any very hard and very flat surface would work well too, but I’ve found it easier to make my own surface where I can control and shim it until it is useful.
A garage floor often is not going to be flat enough to work well. But yours may look better than mine, so that’s another option too. In that case, you just need lots of weight and boards to spread out the clamping pressure.
