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...

[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 ...

[quote user="Romy the Cat"] It is very self-explanatory and liked it a lot. The advantage is that it might be used in any rectangular room and the most important that it is VERY simple to build this way. I think that if I have room then I might stop ...

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...

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...

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="MINGSU"]Have you use GOTO dirver before? Have you try it with the "GOTO" recommendation? Have you listen to GOTO in your own system? If not, I suggest that you do it 1st and then draw your own opinons then. GOTO never said don't worr...

[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...

In talking with Shelly Katz a few days ago, I brought up the topic of how sound is perceived in the context of layered sound or indeed oops. He is a very busy man and we did not have long to develop the conversation, but this is the thrust of what he...

Interesting.
When I moved my system and was just learning the new room and making changes, I was also listening to more Bach than usual. I mostly wanted to play Partitas, Inventions, Preludes, and Goldberg Variations. I was turned off by any cell...

My first choice would be a Sony SACD recorder with storage in SACD format. Quite expensive, but I would not use an expensive Sony playback device. Their early models (still available new on ebay) were designed to show how much better than regular CD ...

I must be missing something - or not be ready for this yet. Here are my understanding problems:1) he starts with the "left" speaker and searches for the best bass. I would think that one should search individually with the left and right and pick the...
