What are the exact differences WRT sound ? Between the 30904 and the 30923. I know the 30923 doesn't have the C-2 R-3 Zobel but what difference in the sound in the horn will that make.

I'll understand it much better if it can be explained in these terms.I know the 30923/30904 are attenuators for taming a High efficiency HF driver/horn for home use.

Does anyone know what the sound differences are going to be between the two attenuators 30923/30904.It says in the Altec literature that the 30904's primary function is to mate a medium efficiency woofer to a high efficiency HF driver.

I had got some answers in a thread i started awhile back about the N1285 and the 30904 that I had received with them.Can be seen here in this thread.

But I never found anything that explained what the differences were between the two attenuators just says they do the same thing so why the two variants ?

Thanks for any help on this as this has been bugging me for a bit now.Crossovers are not my strong suit.As most of you may know.

Happy Holidays !
