You're on the right track. After you have "voiced" the speakers for your listening room replace the L-Pad with Caddock non-inductive R's of about 20 - 30 watt size.
The best way to 'voice' your speakers is to connnect only one speaker i.e.LC or RC, If your system allows it, set the output to Mono so that you're getting both channels thru each speaker. Turn the MR & T L-Pads down all the way and play something that has a fairly well balanced tonal spectrum. Slowly turn up the MR L-Pad until its' output is equal in volume to the woofer when you are listening with your head close to the speaker enclosure (known as "The near field method"). Then repeat the process with the tweeter until its' output is equal to the Woofer & MR. This should be a slow and relaxed process.
Disconnect the voiced speaker and connect the other speaker and repeat the process. Check the results of these setting at the norma; listening position and adjust as necessary. You have now voiced both speakers to your room. Listen to them for several listening sessions, during which you will tweak both speakers' settings. After you are sure that they are voiced to your satisfaction disconnect each L-pad in turn and use a DVM to read the resistance of each L-Pad's legs and record your readings. These are the values of the Caddock R's you will need to replace the inductive wirewound L-pads with solid-state non-inductive L-Pads. You should notice a significant improvement in resolution of fine detail, transient attack & decay, etc.
Happy Listening !
