Like I said, Elliot. Best to set the L pads where you like the sound. Then measure the resistance across the L pads. Then substitute the L pad with a high quality resistor of the value you determined by measurement across the L pad. The best L pad is no L pad. If you want further guidance, I recommend 12W Mills non-inductive resistors for this purpose, available by mail from Michael Percy Audio. For better power handling, you could parallel two or more 12W Mills'. For example, if the measured R across the Lpad at your preferred setting is 10 ohms, then buy two 20-ohm Mills from Percy and use them in parallel for a net of 10 ohms and 24W of power handling. Or you could buy four 40-ohm Mills for 48W, etc.
L-Pads. Speakers Awful Without Them, New Ones Ordered
I removed the L-Pads, the tweeters are way too bright, screechy above mids. Disturbing. Played my best source: R2R, Sgt. Peppers. Normally magnificent. Unlistenable!
Using my Chase Remote Control to cut Treble temporarily, until new L-Pads arrive.
I ordered these 16 ohm pads:

mine don’t have the issues he discusses, my insulation is modern, crossovers are tar filled metal cans, not much heat in 6.3 cu ft; these and originals were large ceramic body.
Will put the tweeter ’Brilliance’ ones in first, listen. Then add ’Presence’, listen, decide: leave in, or out. IN more than likely. They (orig and 1 set of replacements) have been IN for 62 years.
My original bronze ones came from original Fisher console, they were a custom version, still labeled ’Brilliance’ and ’Presence’.

Many of these old Electro-Voice designs had L-Pads (16 ohm used AT37 Attenuators; 8 ohm used AT38). 2 way have one. 3 way designs have two: ’Brilliance’ and ’Presence’.
You can balance the drivers to each other, and to each space, and as you age, ability to hear highs diminishes, you can creep the tweeters up speck by speck. Imbalance due to irregular spacing: adjust each individually
I’m not going to measure and install a fixed resistor, I want future adjustability.
’L-Pads: Terrible Idea’. Bullshite, everyone who ever heard them loves them!
And, let’s not forget, the originals, with L-Pads, first one mono speaker, later two for stereo, are the designs that made these companies successful.
