It is a three way design using ScanSpeak 18W8545,18W8546 and D2905/9900. I found several european speaker DIY site which has this speaker in it.
It seems to be a good design. Just the fact that it's three way using all scanspeak drivers.... Anyone tried it?
For those who are familiar with this design... its baffle is tilted 18.25 degrees from vertical. i.e., all the drivers are slightly looking upward. What's the reason behind this? if I make the cabinet with same internal volume but with a straight vertical baffle, will I get a "wrong" sound?

The reason that the cabnet is slanted back is to align the acoustic centers of the drivers. The acoustic center of a woofer is not at the open end of the, but a little behind that. Adding a crossover to the drivers (a necessity, of cource) can change the centers relative to the other drivers. A sound coming from one speaker might lead the sound coming from another speaker by 90 degrees. Another phrase for this is "group delay." If all three drivers were out of phase with the others by 90 degrees, then putting them in a slanted baffle would align them.
As for your other question, I have never heard this particular set-up (I'm too poor to play with Scan-Speak).
As for your other question, I have never heard this particular set-up (I'm too poor to play with Scan-Speak).
I've heard this particular speaker at a diy-shop in the Netherlands, It has a neutral sound and the sound is rich of detail, imaging is also good, but the problem is that I've auditioned only for a short time, it's too expensive for me, and I wasn't as impressed as the driver line-up would suggest.
The people of the diy-shop said that it was a very difficult speaker to drive, because the impedance load dips <3ohm! So the amp which they used (vincent amp) hadn't enough power to control the speaker. This speaker also needs a big room, the auditionroom was not large enough. The room has to be >30m^2
So bottomline is buy it if you have got a beast of an amp which is stabile at any load. (pass? rotel 1090? or an other powerhouse) This speaker deserves an hq frontend.
If you doesn't have the above conditions, plz build the reference monitor which IMO is better (not in the bass department ofcourse), it's more subtile and has better imaging (it's a monitor speaker) and is a little less amp dependend.

All this speakers are auditioned in a shop, not my own room under ideal conditions (sunday night
own set). So the listening impressions aren't optimal and are subject to change (mostly in a positive way)

This small speaker looks very interresting.
Do you happen to know how it compares to, say....
Proac Response One SC
Totem Model One Signature
Merlin TSM
or any other high quality manitor?
I am thinking of building a small speaker for my little room, but I have never heard the Ref Mon
Any subjective listning impressions would be appreciated.
Thanks

I haven't heard the commercial ones, so sorry about that 
A free translation of a Dutch reviewer about the Ref Mon.
"Imaging was excellent both in depth and width, the soundstage was big. The bass was extremely controlled clean and transparent. The highs were detailed but modest (I hope it's the right word for "ingetogen") The mids were very detailed. It's a very fast speaker. The speaker was capable of presenting to the listener even the smallest and most hidden information."
Most of these statements I recognised when I listened at the diy-shop (also for a short time ~30minutes).
I'll hope this helps.

Yes this helps, they seem even more interresting now.
I`ll gather some more info around the net before I decide on a specific speaker.
Btw, I have a comercial speaker with Scan Speak Revelator (Doxa 8.1 Revelator) and it is absolutley lovley up in the highs, so I really would like a design using this tweeter.
Ok, thanks again.

Scan Speak reference monitor
Hi to everyone,
I have ordered the drivers and crossovers from Rolph at audiocomponents.nl (email: info@audiocomponents.nl). The prices where the best you can get and the service excellent.
At the moment I am wondering whether to build them out of mdf (cheap version) or solid 5cm oak (expensive version). I am also trying to decide what to use as damping material.
It would be nice if anyone else is interested in this speaker to exchange ideas. I beleive that for small listening rooms it must be very good. I am planning to match it in the future with a sub-woofer.
Question: Can this speaker be driven by an aleph 3 or 5 or Zen ver.4 amplifier. Which is the better choice?
Thank you all for reading,

Re: How about "Reference Monitor" ?
Read the 3 posts above yours, that's all about the Ref Mon.
gchrist:
I would go for 22mm MDF wit lead bitums (http://www.intertechnik.de/shop/artikeldaten/datenblatt/1343345.html) and the front baffle twice the thickness, so 44mm, also I would add some bracing with 18mm mdf (for an impression look at
edit: about the amp I would go for an volksamp aleph 30 (almost as expensive as the zen v4, but an improved aleph...), but I haven't experience with one of the pass designs. It's just a feeling after I read the review on enjoy te music -> http://www.enjoythemusic.com/magazine/equipment/0701/volksamp.htm

An externally hosted image should be here but it was not working when we last tested it.
) But compensate for the extra volume, keep the original volume. About the crossover use Tritec coils and Audyn or Mundorf caps, it is expensive, but worth the trouble.

(in a positive way), the highs aren't as detailed as the Ref Mon. (less analytical, more musical and modest), there is also a small dip in the lower mids, but this is only noticable if you change to a speaker which excells in it (e.g. Ref Mon). I like the Event very much, only it was a bit to expensive for me (I'm a poor student
ss isn't the brand for students I'll stick with Vifa )

Clone of the Reference Plus
There is a fellow over in the Netherlands who devised a "clone" of the Scanspeak Reference Plus. His name is Edgar Beers, you can find his web page here: http://members.home.nl/edgar.beers/eveII.htm

Well LaMa you are my man!! I was wondering how this speaker sounds! By the way, Vifa are very desent and "honest" drivers. It is very unlikely to be dissapointed by a Vifa driver, but SS deserves the extra Euros! If you can't afford Sc-Speak another alternative is the Audax Aerogel drivers. Excelent mids and well controlled bass with very reasonable prices. If you can audition them somewhere don't miss them.
To gchrist...
Oak is just natural wood with all the ads and disadv that comes with it. This means that it is possible to see cracks after six months as the wool will dry. Thicker materials will also increase the size of the baffle (wider) which is going to affect the stereo imaging. I would use marine plywood with MDF as sandwich. Try 16mm plywood+8mm MDF and inverse this (16mm MDF+8mm plywood) for sizes with the same dimensions. This will attenuate box resonances as every side of the box will tune to different frequency.
Tou can't avoid internal bracing in a speaker with the size of Reference plus unless you built them with marble!!

Jonny1,
You are correct about the bracings, but I was speaking about the Reference Monitor (not the plus version) which is a small version of the Big Reference Plus.
I was planning on building the front buffle out of two 19mm MDF parts. The original plan was for a 30mm MDF which I could not find in the shops. Will this affect the quality of the output?
Thanks
