The KEFs have been Klippel tested and the results are on DIYMA.

I found a review of the Q100 on zaphaudio and a review of the HTS3001SE from diyma member 'bikinpunk' here:

Kef’s HTS3001SE… I cracked the Egg! | Medley's Musings

But both of those drivers are larger and more expensive than the one I have. Also, the small cheap Kef driver, the one I bought, is quite a bit better suited to horn loading. This is because the cone on the cheap one is much much lighter, yielding a horn-friendly qts value.

Seriously, try the 3005SE's. (I know "bikini" Erin is selling the pair he tested...)

I have some of both the 1005.2's (I think that's the number) and the 3005SE's, as well as Q100's. Imaging is a step above, perhaps due to the proto-Tangerine phase plug on the tweeter. Not to mention the extra octave of extension. They're the best thing in that size class I've ever heard. The Q100's better them when playing loud, especially in the upper midrange (much stouter tweeter), but none of these little drivers are really designed for "loud."

The limiting factor there will be the tiny tweeter. Though the small tweeter is the limiting factor on the 3005, too.

I never understood those small holes for the midrange driver

but looking at a bandpass sub it suddenly struck me... they are 'just' bandpass front ports, and can be calculated as such he, thats cool, I want one for my bass guitar

cheers

After 648 posts you finally figured out that the port holes create a bandpass.
Now you are thinking about using a widerange driver without a compression driver in a bandpass .
Small mouth, cone driver= increased mid output, no HF gain.
As you said, rubbish.

not from reading, no sir

but not the reason
low high frequency gain, and increased mid gain would actually be perfect, I could use that ok
but any mid driver could do that...so no for that

though I might still build one, just for the fun to have one and to hear it

The problem with Synergy horns in home type listening situations is that so few people have ever actually heard them that way. I have a long thread going on over at DIYsoundgroup about a DIY synergy horn design for home use - yet, I've still never heard an actual Synergy horn! I'm just going on what I got from following patent descriptions and webposts, no idea what similarities there may really be in sound between mine and real ones. There just don't seem to be many places to hear Synergies, other than maybe in stadiums. Is there any chance of a Synergy demo/audition at some upcoming audio show (east/central area please)? They currently seem to be mythic since people only hear about them, seldom actually get to hear them.

I had the same problem. The way that I found one was by re-constructing the old Lambda Acoustics website using The Wayback Machine, then emailing people that owned Unities.

(Patrick Bateman, Unity Horn Stalker!)

Found someone that lived 20 miles away that had a set and got a demo.
