Attenuator - Valencia

Does anyone know the range of high frequency attenuation that was available on the Altec Valencia?

Did Altec use an L-Pad, a series of resistors or a transformer for that attenuator?

Of the available alternatives what is the best method to install attenuation in a modern day version of this speaker?

Thanks,

I finally found one of the recommended Altec crossovers for my 416A and 806A.



It is Model N800D and it has 5 taps. The first position is 0 and the 4 remaining taps increase by 1 dB. It is referred to as a shelving control. Don M
