Hi!
Today I receive a pair of Scanspeak 18W8545 and a pair of Scanspeak D2905/9500.
I would like to build a pair of loudspeakers, probably Sonus Faber Electra Amator II clone.
Is anyone at this forum use this combination ? Is anyone who build a Electra Amator II clone ?
I will drive this speaker with Aleph P/Aleph 5 clone.
I think that XO can be simple 6dB/oct with a little resistor correction on tweeter.
Any Idea on design ?

Hi kirc,
I have some expirience with SS8545 driver, but I used it in a 2way project with revelator (9900) tweeter.
First order crossover can be used with SS8545 but not a simple one, because to linearize its response one have to use large inductor which leeds to low crossover point (<1,8kHz) and still has too easy post xover-point slope.
I used 2nd order crossover with few compensation notches, and I'll post measurements graphs and schematic later if you are interested.
regards,
Vuki

Here's one with the 9300 tweet, which is pretty close to the 9500.
Making of M1
That should make for a very nice sounding speaker. It could need some (very) minor tweaking for the different tweeter, if any, depending on your preferences in voicing.
Cheers.
