just looking for input on basic design.
specs are dead on for drivers and cross over is being professionally designed.

what speakers??

a ring radiator and 4 6.5's. I don't like giving brand names because then it becomes more about the equipment then the actual design.
I'm sure I don't have to tell you it's good stuff. Comes out to a little under $2000 each tower. enclosure is 1'' thick and planing to use bamboo plywood. I may run bracing in it as well.

I think that you should use oticica to build them... beautiful wood, very dense, and VERY expensive...

If I was to use any exotic wood it would still be made out of bamboo just use exotic veneer. I have a hook up on bamboo and want to try it out for a car build.

That's what I was thinking it's amazing what you can cover in laminate/veneer!

I'll have to see how the xover comes out. I'm horrible at x over design, especially at attenuating a tweeter while leaving it loud enough to blend with 4 6.5's

I had some sick jbl's back in the day the where dual 6.5"s with a bi-radial silk dome tweeter mounted in a horn, the nice part was they where bi-amp capable so running the horns on separate channels so I could bring them up/down as needed, but they where almost exactly like your design minus 2 6.5"s but ported the same way back when a flared port was a "new" idea!

lookin good. are you going to round over the bottom half of the stand?

wenn_du_weinst
06-06-2012, 06:22 PM
I left .5" after the round over to help it be more stable. They won't be 45 they will be a 1.5'' round over I was just to lazy to do round overs in sketch up it's a pain in the ***.

this is how the bracing will be, I need to point out no bracing is directly in the center of any plane, and none interferes with the 1/4 wave function in the enclosure. The random size and location of the round holes in the bracing breaks up standing waves as well.

For $2000 a tower, much better can be had......much much better.

put up or shut up.
I do find it's funny you say that not knowing anything other then the layout. If you post anything klipsch you need your head checked.

You can get nice CBT arrays for less than $2 grand a tower. I can tell you right now with a single round tweeter, and a couple 6.5's you are not going to have great dispersion in the upper end, and you will have next to nothing for low end extension, and you will have common beaming issues seeing as you are using a flat array.

If you want to look at some great array designs....have a look here - Speaker Design Works (http://speakerdesignworks.com/NS6project_1.html)

If you were really serious, you would do a cbt style array, that can be used as a l/c/r and surrounds.

Have a visit to the AVSforum, and look around. You can get into Genelec's for the price you are proposing.

So there.....I put up....feel free to.....?

I'm not a fan of line array's really. they look cool but not as directional as I like. I'm actually looking for on axis sound. This isn't for a HT.
it's for a 2.1 system.

CHEMMINS
06-07-2012, 08:09 PM
Well if you want only on axis sound, look at some good point source drivers and use the concave array. You can localize very well. Toss in an 8 or 10" in the base to give you some lfe using the floor as a loading wall.

meh sorry not feeling the line array's. If I'm going to put that much work into something I'll just run a horn.

Horns are good, just limited range of frequency, unless you want to get real crazy with a multi horn setup in the same enclosure. Not really directional though unless the mouth is really thought out.

I thought for sure you were going to say dipole.

Lol.....never run dipole......

And yes I have been researching the home speaker thing for a long time now. Planning the HT room right now actually, so when I can do the concrete work, it will be go time.

wenn_du_weinst

I was waiting for it the second I typed "directional"
my HT I'll probably run 7 monitors or something that way they are all the same and all internally powered so less **** to worry about.

since I'm such an easy guy to please, and so decisive. I made up some others.
I like the look of the klipsch reference speakers but didn't like certain aspects of them. So basically the same look with better components and different finish.

Wait, you starts with ring radiator and 4 woofers, now you are doing a horn and two woofers???

The concern you have with multiple woofers like your original design is interference and comb filtering. The PLD of the top woofer is different than the bottom woofer at any listening position. They will not act as a linear array above a frequency that correlates to the spacing. That's why successful line arrays use many tiny drivers, or heavy processing to align them (in pro audio).

Paradigm Has similar designs, except only one woofer is the midrange. The rest are midbass.

If I had that budget, I would buy Paradigm Reference or Dynaudio.

If I was building your enclosure and crossover, it would be a 3-way design and the top woofer would be in its own enclosure volume.
