Parts Express Speaker L-Pad Attenuator 50W Mono 1" Shaft 8 Ohm
I am restoring some Knight 2350A speakers. The crossovers are original, I believe, and the l-pads do not appear to work. The speakers are rated 8 ohm 70 watts. Would these l-pads work for that application?
Yes these L-pads will work fine for that application.

will this work for a 4ohm tweeter?
Have a morel mdt30 4ohm tweeter and and SB13pfc24-08 8ohm midwoofer with a custom crossover done by simulation. The tweeter needs attenuation and I do not own the proper measuring equipment. Will this 8ohm L-pad work with my morel 4ohm tweeter?
This is only designed for 8 ohm applications unfortunately. We do not carry a l pad that is compatible with 4 ohm loads at this time.

where to insert a phase reversal switch into the network
I have used this 260-255 L-pad successfully to attenuate my mids, (and another for the tweets), but now wish to begin experimenting with home-built crossovers. I would like to be able to add a phase reversal switch (DPDT) for the mids - my question is where? - on the crossover side of the L-pad or the speaker side? Or, am I missing a better option?
Best bet is to do as the last thing before the driver that way it works as if you just switched the leads on the driver itself.

What is the max attenuation of this l pad?
The maximum attenuation will be at or near 100%. Full on, turned all the way to the right, will be no attenuation. Full off, all the way to the left, will be more less off.

L-Pad Rating Decibels vs Watts?
I am refurbishing some ESS AMT1b speakers from 1979. Each speaker has 2 L-Pads, one to control the "Midrange Presence" and one to control "Brilliance" The specs written on the L-Pads say 8ohm 50DB. I am confused about the rating in DB rather than watts. What should I get? Would one of your 50W or 100W L-Pads work satisfactorily? Thanks.
back then there were two types of l-pads one with audio taper and another with linear taper and both were constant impedance but the crossover was affected by the wrong one. linear taper was more for circuit use and you should use audio taper l-pad ,use the 100watt dayton I MODIFIED THIS X'OVER MADE IT A THREE WAY ,USED AN AUDAX 6 FOR MIDRANGE,SWEET FOR 1979! Unless you are simply restoring these speakers and they have a good home. the crossovers leave much to be desired electronic x'overs are best , fmods and sure products could bring these to state of the art level and not spend a fortune[save diaphragms also electronic x'over don't blow ribbon from spurious wave forms]
