Cool project! For the name how about just 24? Yes it's a direct ripoff of the show but it has a dramatic effect just like the appearance of the speakers do. Just a thought.
thank you thank you. )))
Stock DX25 may be slightly more sensitive compare to ProAc version. Other then that, I think you could. FR looks almost identical. I can alter the crossover for stock dx25 as well. Want to send me one? I may just buy a pair later and use them somewhere along the lines but it'll probably be in 2012.

I've just finished a partial review of the original thread, gleaning a few details about how your design has progressed up to this point. I'm going to build a set, after the holidays, as soon as things are finalized sufficiently. Are the original dimensions and spacing going to stay the same, or do you anticipate optimizing the layout in some fashion? Starting in late January I'm going to have an overhaul done on my feet (one at a time--I'm told I've worn them out :() , so I'll be hobbling around for quite a while afterwards. Is it too early in the design phase to start cutting wood?
Interesting build, and an interesting comparison for a guy whose built full line arrays. Most agnostics would be dead set against your focused array but your ears would certainly tell the whole story. I know they're not done yet but how do they compare to your full arrays? And what was the qtc of that Sony woofer?
I'll end up divorced if they do. Wife loves the music but we have too many speakers at home already. I may build another pair or two and set up a HT in the shop. It would be interesting to have dipole HT. Dipole center channel anyone?

The dimension will stay the same so you can start cutting the wood. I'll be working on crossover some more (spend 4 hours on it today) Also, experimenting with U-pole idea and that's basically a pair of side pieces that can be added later on. At this point I've leveled out the response throughout the mid range. The remaining issue is raised response from a 100hz to 500hz. It's about 4db up. I am not sure yet if I want to have flat FR because this array is a dipole and summed up arriving signal will look and sound different. Notch will stay the same.
Brewski heard one speaker today and I think he liked it.
Couple of things about how I design.
After crossover adjustments, I'll listen for a few days or so. Only one loudspeaker. Don't want to go in to imaging while linear performance is getting worked on.
Linear response is very important. Dipole however is more complicated then sticking microphone 1meter away.
More common sense measurements are required.

The Qtc of that Sony is 1.0... something something. It's a stiffy with weak motor.
This array is not a focused array, it's more of a line source with a single centered tweeter. Focused array is even more like a pair of headphones. You can walk through the sound field. In the sweet spot, they are sweeter. The presentation is even more life like but apparent size of the instruments is somewhat smaller from straight array.
This Sony array is not going to sound anywhere as good as Alice. But, it's a dipole, in the end it'll have flat frequency response, low distortion and a large stable vertical image. It works in to 100hz area. I'd prefer an array like this to a wide range of a conventional 2 way designs.
I wouldn't use one large sub for the base but a pair of 10"inchers will make it a full range system. And $80 in parts including crossover? Anybody would be very hard pressed to get a better sound/presentation at the cost.
I'll describe the sound as I go alone in development.
I think you are in NJ? Come by and listen then you have time. I am also interested in collecting opinions.
I got to hear them for a bit today and really enjoyed them. The Sony driver is again really pleasant surprise cost to performance wise they're off the chart. I'll look forward to hearing the finished version once they're done.

I heard a lessor version at romans a few months ago. it is a very nice driver forrrr under 1 dollar!
thank you thank you. )))

I don't have one at this time, but if you can provide another crossover based on that tweeter, I will be more than happy to build one, if not two pairs of these for my home theater. I can easily pick up a 6' plank of 3/4" southern yellow pine for $32 and not have to do any cutting at all; just routing. It would be a surprisingly simple project for me.
