Thats the kind of stuff I was hoping for. I appreciate the help with this, there seems to be a scarcity of horn related discussion on the web and its proving hard to learn the ropes.One other unrelated question that could save me a lot of trial and e...

Dear All,I wish to commence gathering the components and finding the craftsmen necessary for my DIY speaker project, but wished to bring my proposal before this forum in order to establish whether it's intrinsically worthy, and whether any simple imp...

[quote user="AOK_Farmer"] Here's what I've been trying. 8 ohm 4.5 inch full range Omega driver in a 0.35 cu ft sealed box and 6 mH coil 200 Hz electrical crossover. The main speaker is JBL Array 1000. This full range driver has my favorite *tone* of ...

I think it is absolutely not need to discuss how Fostex tweeter sounds as it might sound like anything. Type of crossovering, type of amplification, type of electricity, type of loading, type of time alignment and the precision of time alignment migh...

Maybe, but from a practical perspective, theory can be pretty useless as the listening experience is the cumulation of many factors. My experience (if you care) is that at lower frequencies, room modes get increasingly more difficult to address but ...

Midbass from horn in
small room can be hugely benefited if it bounces but to make the
assembly of horns visually pleasant, time aligned and functional at the
same time is a big question. I do like the notion of Midbass fires t...

Guy, here some unconnected comments that you might find worth considering. They are in no order or importance, just random thoughts.

Hello Stringreen,
First, though I do use it, I think the term "time alignment" is a misnomer... We should really be calling it something else.
When you say "Time Allignment has nothing to do with the placement of instruments in an orchestra", y...

That was a subject of long consideration for me and I ruled
not to go for time alignment. You see, my current listening
position is 8.5 feet from the diaphragms and my ceiling height is 14 foot. Let pretend
that I am siting at 4 feet at my listeni...

[quote user="Romy the Cat"] Ok, I do officially like this “Battle Road” hours. Upon many considerations (and there are 4 ways to implement the midbass horn in that room) I have inclined to my leading idea to do it elegant and with time alignment....

Keith,
Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a w...

[quote user="noviygera"]I have been thinking about how nice it would be to have have a good sounding DSP for crossover and delay functionality. I know this subject was covered here before but what was talked about is this DSP is not that good, and th...

Hmmm... Thorny, difficult topic...The "integration" of HF certainly involves its "disappearance" - as "HF", as such - "into the soundfield". At the very least, Tone ultimately depends on this. But there also appear to be other benefits from "ge...

There are a few at least theoretical backdraws for the Array in my view.Of course having a lot of different drivers playing at the same frequency implies that all of them should work in perfect unison, if one starts lagging a little bit it will mess...

Since I change the transformer I picked some harmonics and now I feel that my midbass has a bit too long roll off. I moved the second low pass filter close to the first filter. After a very careful listening and some thinking I ended up with setting ...

[quote user="MINGSU"] Time-aligned is an impossible task from my point of view. How can one perfectly time align different drivers? Align to what precision? mm, inch, cm or ft? 5%, 10%, 30% time align? Align to the tip of the cone or middle of the...
