For more precise informations better ask Mr Pass or Wrenchone.
This speakers was chosen to match the new Papa sit amplifier.
Personaly i have good apreciation of open baffles with full range alnico.
I use two full range alnico Philips 30 cm without filters
and minimalistic class A amp its sound fantastic without tweeters,
but if Your taste is tweeters enchanced maybe like on this video

Philips 9710M/01 (alnico) - YouTube

however , if parafeed is a must , I think autoformer on end is better solution then "regular" arrangement , due to tighter coupling
Yes, I agree...As I said I will try some day...!

I see...Thanks...
After 12inch nirvana driver I went to a 4inch jordan watts whit kef passive membrane and the results are shocking. If you like huge orchestral music this is so evident...The punch and timing are exceptional good, bass tight and precise. If there is an huge dynamic outbreak of energie you fill it...Some would call this fundament.
So I think the Pass speakers should be interesting, the sub is a 12ich driver and the full range a lowther...Here you have a very good sounding alternative from Sonido...also alnico...

Nice day to you tooo...

I am just wondering is there a hybrid SIT brother out there somewhere?...
I hope not!!!

Update on my SIT: The amp has played a couple 100h, works stable and
sounds incredible!

Have fun!

Recent auction on LS-33 went for a little less then 500USD,
they are worth every nickel!

From the last revision, I installed a grid stopper in front of 6e5p and changed the PSU for the tube a little bit.
Now I am very pleased and dont want to change anything more.
Thou I have a few 6e6p-dry tubes whit gold pins, I dont think they could make a very big difference anyway...

Update...
I will try the Pass floating Bias on my hybrids....
I changed the main loaudspeakers to infinity quantum 5... Madness some will say!
The ACR are around 90dB and the infinity monsters, I dont know...
But the sound is even better. Its evident that 10W cant drive 250W speakers to nirvana,
but at least there is the whole spectrum present. I get very deep bass from the infinitys,
the mids and highs are wonderful like on a good tube SET...I am very pleased whit the results.....
Let the hybrid SIT do some real work!
