Ev centurions - crossovers x336, x436?

[loudnoises]

Chewing my way through these, the only thing that I can't explain is that one of the two has an x436 crossover, the other has the usual x336.

I can find nothing on the x436, save a mention of it inside a magnavox console (running the usual centurion components in a standard box). As far as I know it differs from the x336 only on that it has a 400hz lower point vs 300hz.

Thr ev literature I've found has no mention of an x436.

The x436 is paired with the usual centurion components, the x336 is set up with the senior centurion kit.

So where did the x436 come from? Was it a "best I could get" replacement or is it possibly done to balance the two speakers? Short of ax x336, the x436 is the next best option ev seems to have made at that time. How much of an affect on the sound is that 100hz? Slope is 6db

Obviously I'd prefer they were fully matched. In time perhaps.

I'd guess that the X436 was a response, to a need for greater robustness or power handling in the speaker system. There were probably some midrange driver failures- a slightly higher crossover point should help to alleviate that a bit.

I found a case where this crossover was used with Centurian components in a Motorola console- it was with a PP EL34 amp, probably close to 40 watts. I'm betting that console was capable of playing very loud! That is a lot of power for the time in a console- there may have been a need to beef up the power handling, under that condition.

I think you found the same console, and I messed up the brand.

I'm curious to see how they compare. 300 seems so low for the mood, not that I'm second guessing those old farts back then
