Hi to all
I need a suggestion....
I'm looking for a new loudspeaker.
At the end the candidates are
Troels CNO 2.5
CNO 2.
Scanspeak Reference Plus
Scan Speak bouwtekeningen
The reference is cheaper about of 300 €
I have to use with my valve amp (50 watt).
and the winner is..... 🙂🙂

great...I had a hard enough time trying to figure out wtf I was going to build...AND YOU DO THIS TO ME!!!!
Have you looked at Troels DQWTL plans? It seems you want efficiency for low wattage applications.

I think that DQWT plans of troels are too expensive.
My valve tube is a push pull 60 watt, for that reason not poor, i think
that reference or CNO are ok for him
I dont know sensibility of reference plus loudspeaker,
the CNO 2,5 has 91 db...

Yes it is expensive...95 db sensitivity if I remember correctly. I do like your choices though. I would lean towards Troels model. His research in the field is something to NOT take for granted.

For that reason I understood that you advice me CNO 2.5 instead Reference Plus.
Really sensibility of Reference plus is 95 db?

The DQWT is 95 dB, the CNO 2,5 is 91 dB.
There are no data for the Reference Plus, but the tweeter is 91 dB and has an L-pad, so overall sensitivity should be lower (86-88? dB)

Hi
You should also consider Zaph's 2.5 way version of the ZRT: Zaph|Audio - ZRT - Revelator Tower
Complete kit available from Madisond at excellent price for us Europeans (even with shipping): https://www.madisound.com/store/product_info.php?cPath=35_425&products_id=8448

I'd be far more inclined to build the Zaph design. The ~3.4khz xover point used in Troels design doesn't, imo, make the best out of either of its drivers.
The tweeter can handle a really low xover point so why not exploit that factor? You'd end up with better off axis performance, lower distortion and better stored energy characteristics if you did.

On my scan have the troels xover , very good ,is a key in speakers...
I vote for Cno2.5, low impedence but tube friendly..(you have 4ohm tap?)
ask Troels, is nice man , put your name/state on mail...

Zap very nice too
dont worry for upper xover point ,sound a lot better 😉
my 9700 sound better on troels vs my at 1800hz (all 18db)
PS
Now I'm openbaffle fullrange ,no box ,no tw and xover on the midrange...a lot better

IMO, for midrange, the SEAS Nextel drivers sound better than the SS drivers. Quality of tweeters is a tossup. But, for the critical mids, the SEAS Nextel drivers are better. On the other hand, the Scan drivers are better with bass. If you were looking for a 2 way with good mids and great bass, the Scan drivers are the way to go. For a 2.5 way speaker, with an extra woofer to fill in more bass, the SEAS midrange will sound more neutral and clear without being harsh or bright.

Tyson you are right ! IMO 😛
troels 3way I Thinks the rigth choice, there is one design with nextel mid OB ....
tw seas I don't know...but the alu 9800 sound a lot better then 9700 ,sweet yes more sweet !

Scan Speak woofer is the best on bass, but Reference plus has smaller sensibility.
CNO with 91 db is more suitable for tube valve (probably).
ZRT play gooseberry 🙂
I thinked to write Troels but in your site he said
"do not ask me is it better one or another speaker" ... (I understood)

yes😛 but you can ask about impedence .... and general info 3way VS 2.5
the cn02.5 is low (3min)but more important is how the curve work , this is the most important for good bass and controll on tube amp ,but if you have pp 60w with feedback (ie good dumping factor )I thinks is ok....
yes my small 15w is incredible on bass🙂

my view is for diy xover 2-2,5 is simple and fast only one frequency cross , software and ear with some work ...
3way is a lot more difficult for diy's , but with troels work con sound only better , big woofer not 6.5" that are midwoofer , and the two cross way out the midrange range....
size matters . 300mm is so clean and powerfull

.... I do not want a 3 way 🙂
In this case we speak about 2,5 way, and about three loudspeaker.
CNO is 2,5 , Zaph the same, and Reference too..
I saw a lot of loudspeaker, but at the end these are the choice (same way, cost, dimension and son on)
Add other alternative will be make the choice more difficult and I will return on the sea 🙂
I'm reading that reference need a muscle amp for sound better ... and has lower sensibility...

.... remain CNO or Zaph revelator tower....

I recently chose Troels jazzman. The impedance is good for valve, not overly sensitive but a good 3 way design
IMHO, the reference plus is a 3 way design: 2 separate chambers for bass and mid-high, vented for bass and closed for mid, and a xo in the region of 100 Hz for the bass. The fact that there isn't a high-pass filter for the mid is because the "mid" (a 18W8546) has a low resonance point and is damped by the closed box.

I like a lot the scan tw
but the 9900 is the same as my 9700 (diff:front plate has more controlled directivity on9900) is old design the 9800 sound a lot better .
PS
3way have 3unit, the same as 2,5 the cost is the same ,but 3way sound a lot better ,period!
2,5 have min 3ohm ,thinks a little ....
