Understanding Line Array SystemsBy John Murray
Behind the buzz, there are a lot of factors at work in line arrays. An explanation and comparison of current models. This discussion can’t be contained in just a few paragraphs, so we must start with th...

[quote user="kodomo"]I am using sealed bass arrays of 3 per side. I have six 10" scanspeak woofers in total. I aim to operate them from 38hz to 160hz with qtc 0.707I also have a tapped horn that I am using with my current horn system. It is 244cm's h...

I heard the Array 1400 at a show: https://www.neomax.ro/produs.php?id=P:5737-S:336It has the aluminum diaphragm rather than beryllium.The demo music sounded very nice. Effortless and beautiful.The midrange tended to spit and shout a bit though, like ...

[quote user="Romy the Cat"]Here is the idea that I had for the “ultimate bass” for my room. Below is the picture of Macondo one channel as it is now from my listening position. So, if I find a way to deal with the wall edge at my ceiling then I migh...

Your Typical Acoustical Suspension-type Loudspeaker enclosure witch has less then 90 db at 1 watt does not belong with a horn system that starts at 110db at 1 watt, even when you ad more then 1 driver, it is still way to far off to even consider usin...

This weekend I visited a friend of my in NY who played to me his playback. I need to say that I did not care too much about his playback and visited him as I like him not his audio adventure but the Sound of his playback did surprised me. It was not ...

Maybe you are talking about Array 1400 model?...

Yes, Haralanov, thanks. I just goggled the JBL Array 1400 and they did look what I heard: http://www.jblsynthesis.com/downloads/products/prod_94_634484048356173879_Specification%20Sheet%20-%20Project%20Array%201400.pdfVery accurate and surprisingly 8...

I come up with the idea to introduce 6th channel and add bass array in between tapped horn and upperbass horn. Benefits:1. I can use 1st order lowpass for Tapped Horn at 15-20Hz2. 30Hz+ range become time-aligned3. I don't need to go very low with upp...

But Romy, you also have the different channels in a curved array ? Whats the differenceI know your's are time aligned but the Utopias must be as well.Collin...

Recently Macondo was altered and converted into… nope, not into a Super Macondo :-) but in a “Larger Macondo”. The Super Macondo it will be when I resolved how to implement time delays along with a low pass flirter at midbass horn, that would enable ...

Bass arrays are considered infinite when they cover min. 70% of the room height. It is also important that they are mirrored (ceiling perpendicular to the array). Your new room is not ideal for bass arrays.I don't know whether you have read this pape...

I am glad to hear that I am not the only one who is overwhelmed by compression drivers. I tried the A7s way back when they were current and everyone's favorite, and I tried various modifications with like-minded friends; but I came to the concl...

[quote user="oxric"] I like the idea of angling the enclosure, although I am not sure about the idea of the lowest drivers firing at the floor...I would use a series of modules each containing two tightly fit drivers which would fire parallel to the ...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

Thanks for explanation bout the USB transfer 2.0 speed – I really do not understand it and I very bad with hardware. I was looting into 3-5T disc array. I have seen a few of them. USB and SATA for around 300-500 but the all use small individual disks...
|

Jorge,interesting findings. However, the tall arrays with small woofers is actually worth exploring further based on your findings. I am theorizing, but perhaps the "smearing" effect you were finding in comparison to the midbass horn was due to the h...

Consider treating the problem at its root.Why not build a simple dedicated PC, running Server 2008 with a RAID array? I recently added a RAID 10 array (8TB, striped and mirrored), to an HP workstation... The result is fast, secure and dead quiet.jd...

Continuing to harass the readers of my site and myself with the good news about the performance of my SA8535 driver I would like to post a very educational article about the subject. As I told before, being familiar with sound of ribbons then never i...

[quote user="slowmotion"]But not everyone agree with you there, Romy. If I could make the directivity reasonable constant through the frequency range....all the way down.... An array of tweeters is the last thing I would do.... [/quote]I disagr...

Dominik, in terms of technology advancement, it seems their new driver is better than their other models. But despite this, I’m not sure their transducer engineer knows how to make the drivers to be valuable in terms of sound/tone. I’m saying that n...
