Default AE1 Series 11 crossover schematic

Hi Everyone, I have a pair of AE (Acoustics Energy) AE1 Series 2 reference speakers that have burnt crossovers. The crossovers are potted and there is no way of identifying the component values.
Does any one have a schematic for me so I can re build them.

Just curious, if they are potted, how are you so sure it is the crossover?

Best,

E

Just looked at the impedance plot, I think this is your speaker:

Acoustic Energy AE1 loudspeaker 1992 Measurements | Stereophile.com

There's some complicated stuff going on. The Actual tweeter/woofer seems first like it could be 1st order filters, but there's also tweeter EQ and a notch filter.

I hope you find the data you are seeking, because it would be quite a bit of work to try to reconstruct the crossover otherwise.

If it were me, I'd consider swapping out the tweeter entirely, and starting fresh, but I can pretty much guarantee it wouldn't end up sounding the same. The 1st order filters seem poorly matched and at least a partial cause of the saw-tooth response curve. And that tweeter looks terrible all by itself. Many inexpensive tweeters now outclass what was considered good in 1992.


Best of luck!


Erik

What ever got hot, burnt a 1" dia hole in the potting.
Hope there is someone out there that has an idea

Well, how do you feel about using a Dremel?

If it is in fact just 1 resistor, then you can approach this issue experimentally. You might get lucky and be able to read the original value.

Best,

E
