Don't confuse expensive with decent. My Synergy build uses some buyout drivers but that's because I haven't found any non-buyout ones that would appear to work any better (or even as good).

Also some similarity to an AMT. Are the upper and lower ducts to the center of the M2 offset/isolated from each other or are truly open/in parallel?

I was happy with the synergy design with the clarion drivers, but being the kit was designed in Australia with odd drivers made it impossible for me to get it at that time. I was thinking about trying the pyle mids with the unity horn design just for fun, after my wood working skills improve a bit. The pyle mids are easy to get... But the 2" clarion seemed to solve some issues... Oh well...
P.S... I worked for BB for almost a decade. That place satiated my home/audio car bug when i was younger as I got cost on stuff. Made it easier to play around with stuff... I could own it for a while, then sell it when I wanted to try something else. Hey, if it was not for us selling even basic JBL, I would not know what EOS stood for Of all the years I worked for them, those were my favorite speakers by far... (I liked the advent laureattes as well).

I still want to make a unity or synergy horn... need to improve my wood working skills first.
I was bummed when the S3 horns were made with the orion mids. Too hard to get, especially for playing around. The pyle's look like they are cheap and easy to get still...

Please post the results of your build, I'm curious of what you can get with this driver!
As this was asked about the Visaton M10 drivers way back in october and nobody seems to have added anything since (that I can see anyway) I thought I'd pop something on.

I picked up some unused Visaton M10 drivers off of the bay as they looked interesting and have just tried them out on a 90 x 55 horn that I built.
I haven't done anything special with them, just using two straight 18mm deep x 16mm diameter ports per driver they give a pretty usable frequency range (+/-3db) between around 400hz to 2khz.
The only deviation to that is a 2db bump around 500hz, which I'd probably just crossover a little higher to bring it into line (rolling off a bit below 500hz).

As for the drivers themselves I think they are quite nice little units, the square frame format means the cone extends nice and near to the edge making them easier to get close to the tweeter.
Also because the cone angle is relatively shallow the air chamber in front is automatically small making them easily reach up to 2khz with little or no effort.
I hope this helps.

Paul.

I would love to see the measurements for the Visaton M10s. Since I'm still in Germany for a couple more months I've been thinking about picking some up for a future Synergy build (first want to make some AMT tweeters for the apex).

Is it the size of the horn or the FS of the M10 that is the primary cause the roll off below 500 Hz in your measurements?

Unfortunately I didn't save a plot with Visaton M10 drivers on (just have a few figures written down) and have moved on a bit with that horn with a number of other changes.
So any measurements I'd make now wouldn't be typical ones.

As for the roll off below 400-500hz,
The horn I played with isn't very large with only a 24" x 12" mouth so it may have a bit of an effect.
However having said that when I tried similar midranges with a lower FS figure on the same horn they didn't roll off until around 300hz.
So I suspect that it is indeed the FS which has the greater effect in this case.
I hope this helps,

Paul.

Anyone used a 2" compression driver in a synergy horn? Crossed at around 600hz, midranges covering anything from 140hz to 600.
I have two large phenolic drivers that i can use up to 6000 hz or so. Super tweeter above.

Soooo.. what cheap drivers can i use?
