Woden Empress of India, BVR for Alpair 12pw

[planet10]

Big Vent Relex for the Mark Audio Alpair 12pw. Comment from builder (he may chip in)

I can confirm that they sound absolutely beautiful. Very very good.

Contach me or Scott about getting acess to the full planset.

Any update about sound? Natural roll off on woofer and only capacitor on tweeter something like https://totemacoustic.com/product/element-fire-v2/

 

[planet10]

No info. Another picture. I’d be XOing these 1st order. And i would try the same up high with the horn.

Note: work is proceeding on an A12p variation, Ramillies, there will be a tall & a fat version.

There is no any inductor on A12PW, natural roll off. What is your proposal regarding 1st order high pass filter, between 5 and 10 kHz

 

[planet10]

You are going to have to play. I suspect that the combing issues were what moved the builder to try an upward filter where you get HF splash to brighten thhings up but interferes little with what you here directly.

Nominal 8Ω start with 2-4µF (10-5kHz). Top of the A12pw goes to about 10k on axis, less off-axis.

Hi Dave, any news on the 12p variations yet?

 

[planet10]

I will see, things have sorta stalled on these for the moment.

They say beauty is in the eye of the beholder..... I'm in love.....

They remind me somewhat of the Altec A5, must be the colour.

I need another pair of speakers as much as another amplifier... I must resist temptation.

Any data performance wise available?
