Each pad will have three terminals.  (A stereo l-pad is actually two pads connected to the same shaft.)  Connect the furthest left and right terminals on both pads in one stereo set to the tweeter output of the crossover, negative to one side and positive to the other side.  Continue the negative wire to the tweeter.  Connect the positive wire from the tweeter to both center tap terminals on the L-pads.  Now you can use the L-pad to adjust the volume going to the tweeter.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Should the connections be soldered, or just clips?  Would a four ohm L pad be preferable, or same results?

Soldered is better, and in general the same results.

I finally received my l-pads, they are the exact ones pictured by Stev.   I understand his drawing, but can someone tell me exactly the connection points I should solder?  Specifically the ngative part.

One wire connects to the negative output from your crossover to the negative terminal on the tweeter.  Another wire connects from the same negative terminal on the crossover to both "Right" terminals on the L-pad, which should be soldered into place for best results.

You'll most likely find it easiest to use a short jumper wire to connect the dual right terminals on the Lpad.  Then connect a wire from one of those two terminals to the crossover as DYohn described.   After all wiring is twisted securely to all terminals, solder every connection.

The drawing indicates continuous lines, but the Lpad dual terminals left, middle, and right are each parallel-connected with short wires. 

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

Thanks for all the help.  Justin finished tuning the system, and it sounds great.  The L-pads work better than I could have ever expected, and were pretty easy to install after your thorough directions.   The finctionality of the L-pads makes me question why more people don't use them?   Are most people going active now?

Thanks again Steve and Dyohn.  I appreciate your help.

Glad it worked out for ya!  Commercial system don't use L-pads very often because they can be expensive.  I've used them in installs that need them.  Most commercial crossovers have fixed attenuators that tend to be sufficient for all but the most critical installations.
