just have found the spredsheet for the Synergy horn.
I am currently thinking to use such an Synergy horn based speaker for my upcoming home theater.

My main problem is the size the horn. If I will use for example 4 x 4 inch midrange drivers and 4 x 8 inch bass drivers the box will then have 72cm x 72cm x 40cm with 90 x 90 dispersion horn.

Is it possible to just use 2 midrange and two bass drivers und put the bass drivers on one side and the midrange on the other side of the horn? This...

( for a near field studio monitor.)
Any chances that this product would be produced?


PD: I bought a couple of Seos 8 and I'm toying with the possibility of build a companion mid waveguide made of fiberglass, but is a very difficult process, I'd very...

So, I'm new to speaker building. If your like me, then sometimes noobs get on your nerves too. I'll try not to annoy you guys too much.

Why am I here? Cuz Danley speakers sound amazing. First time I heard them was outdoors. It was an SM96 over a pair JTR Growlers. I was floored by the clear sound. The bass was awesome too. It so happens that I can't afford a pair of Danley's right now. And since I like DIY, I would rather build....

Help me with Synergy]]> 9 Fri, 16 Sep 2016 18:01:22 +0000 http://www.hificircuit.com/community/threads/seos-8-line-array.607/ http://www.hificircuit.com/community/threads/seos-8-line-array.607/ invalid@example.com (Tom Richards) Tom Richards I am interested in building a line array using the SEOS-8 wave guide with a dome tweeter.
The wave guides look like they could solve, or at least mitigate some of the technical issues associated with using domes in a vertical array ? I was thinking of 4 - 5 wave guide / domes per channel.

Does any one know if this has been tried in the past ?

Has anyone published a list of dome tweeters that bolt up to the SOES - 8's ?


Any help is appreciated

I am in the process of building a new home theater, and am exploring the option of using Synergy style horns to control the directivity of the LCR speakers in order to limit reflections off the side walls. The interesting thing about this particular room, is that I'm also building the speakers into the front wall (which has attic space behind it, so I can make any size speaker I want). In addition, there is a pool table in between the front wall and seating (just to make it more...

I got rushed to the ER early last August, and about a week later was diagnosed with "cholangiocarcinoma", a really bad bile duct cancer (20% survival rate over 5 years ). Finally in October, after lots of preparations and pre-treatments, I went into surgery where the docs were ready and expecting to have to remove part of my liver, pancreas,...
