Default 4 sided omni speaker

Hi guy's Just wondering your thoughts on a 4 sided omni speaker? In other words a 12" wide per side 40" tall column with a fostex 103 six inches down from the top on all 4 sides. Should it sound good or not? I'll be series ing them together in pairs so a total of 8 ohms from all four speakers.

4 per tower, one on each of the 4 sides. 2 towers total, a left and a right. Maybe I should shoot for more like 8 inch wide by 40" tall... It will be a sealed cabinet.

Hey cradeldorf, long time.

your describtion on this is confusing, and why I asked

ahh, my english ... six inches down on all 4 sides, means one fullrange on each side, mounted six inches down
I first understood it like an array on each side

so, 8 drivers per speaker, right ?

needs a very big room to be placed far from all walls

can I ask the stupid question ... why ?
I would consider a low 'flooder' omni design instead
with fullrange drivers angled

Hi Cal Good seeing you, long time is right, I'm running the 103En's with just a 68uf cap on the main line. I've had a pair for about a year and the other 6 just showed up today. I'm also using a 12" sub for the bottom end.
Why am I doing this? well when I closed off the back side of my open baffles the other night, they had better midrange and better dialog clarity, but lost all the great hf ambiance and ringyness... the cymbals sounded dead. so I figured by doing a four sided column with a speaker pointing out in all directions that It would keep the great openness sound while still having better midrange and possibly better dialog clarity. I plan on them all firing outward at the same time. and being sealed it shouldn't be out of phase?...

If you are using a cap that size then the cabinet has less bearing on it. Make it to your liking.
