This is one of the surround speakers
after the veneer had been applied. The careful edges were
done using a laminate trimmer bit on my router. The
speaker is sitting on my recently purchased table
saw. Both of these tools are essential to building
speakers from scratch. Without them, you need someone
else to make your cuts (which is a pain if you screw up a piece and
need to cut a new one).


One of the surrounds in testing. It's
important to check the crossover and completely assemble
the speakers and listen to them before final assembly.
Make sure they sound good, the crossovers work, and the
speakers fit properly. Once the veneer goes on, it's too
late to change much. Some people mount the crossovers
externally to allow them to tweak things later. That's
great for audiophile speakers, but for home theater
speaker you need to keep them compact to achieve SAF
certification (SAF=Spousal
Approval Factor!)

This is one of the surround crossovers
after the parts have been glued to the pegboard. I use
carpenter's Goop, sold at Lowe's,
to put the components on the boards. Let it dry overnight.
Notice the cascaded capacitors in the upper left corner.
These surrounds sounded fantastic all by themselves when
I tested them. A pair of these would make a very good set
of booksheld speakers, although I would probably want to
go with something with better bass extension. The F3 for
the surrounds is a little under 90 hz (sealed).

After the speakers were all tested to
make sure everything fit and the crossovers were
performing properly, the electronics are removed and the
veneer goes on. This enclosure has the first coat of
stain. Also, notice that the veneer is bent around the
rounded baffle with the grain. Veneers bend easily around
corners if you make sure the bend is parallel to the
grain. The veneer will not bend around a corner
perpendicular to the grain (it will, but you'll never get
it smooth).

Here are the speakers with the crossovers
mounted inside. Now's the last, good chance to check all
the speaker leads for length. Make sure everything is
long enough (also, you should solder the spade connectors
on now to avoid the possibility of damaging the finish
once the veneer goes on.

This is one of the L/R front speaker
woofer crossovers. I didn't cascade the caps for this one
but I used all Solen caps. Cascading would have been a
waste, I think, since this crossover is a relatively
simple 2nd order with a parallel notch filter. Notice the
alignment of the inductors and the size of the 12awg
aircore.

An internal view of the crossovers inside the surround
speakers. I check them for proper positioning, then
remove them to seal the interior with silicon (use a
caulking gun... it's easy, fast, and a good way to get
the caulk at a decent price.)

Here's one of a finished surround.
