Dear Zigis,

I think Berndt took that link down because there was an error in the text, he put another diagram a bit further down the page:

Thanks jemraid!
Good, I am upgrading my Needles to Tangband, but not ordered notch parts yet, now i now the right parts.

A very quick and dirty prototype to make up for a very rainy Saturday!!
Everything 22mm MDF.

No filters and no measurements as yet.
Hope Henkjan will give some hints.

Dear Patrick,

Wow that was quick and they look very good too. I can't wait to find out what you think of the Alpair 6's, maybe Henkjan's on holiday.

I was thinking of trying the Dynavox FR88EX in my pair, I'm still using the FRS8's.

But, seeing everyone's ethusiasm for Mark's various Alpairs I think I will have to save up to buy a pair.

What notch filter did you settle on in the end for the Needle with AP6 ? .... I read somewhere like 22µF, 0.33mH and 1.8R.

correct

Could you also publish a SPL plot vs Freq ?

Thx,
Patrick

Dear Patrick,

I think you will find this in post 519 - http://www.diyaudio.com/forums/showt...32#post1792032

At least I think t's what you want, I'm not a tech type person like Henkjan.

sorry, I did not save them.. started with measuring, followed by some tuning by ear

Thinking of upgrading from my b3s to the alpair6.

Henkjan, did you also require bsc, or was the notch filter enough?

Henkjan · 20th July 2009, 04:39 PM

just the notch was fine, just like the original Needle
