Romy,it would be interesting to test whether it is really that impossible to get into the near field at 30 Hz as Griffin's simple formula in the line array white paper implies. I am thinking about laying the arrays on the ground, having in mind ceili...

[quote user="Jorge"]I will be dubiuos about the slanted enclosure if not done properly, all drivers must be time aligned and since they are playing the same frequency, deficiencies in time alignment become more obvious. I made a slanted enclosure b...

A $$$ solution for a bass array that comes into my mind are the sandwich cone drivers from Accuton.Monstrous neodymium magnet, underhung voice coil (for low flux modulation).Very low Fs.Relatively low QMS for use in sealed enclosure with transconduct...

It is so funny. As Kitty and I are looking for different
houses we look at different listening rooms and we have different ways to think
about room sizes. She think about space for her piano and size of oriental ran
she would drop on the floor. Wh...

Spent today a whole day moving the boxes, do some measurements,
fighting with REW interface, thinking, some listening… Found some bugs in the
system that I think screwed my initial feeling. The bugs were mostly by Thomas

[quote user="jessie.dazzle"] In the case of a normal ranch style home (one level, no basement) out in the burbs, the attic is wasted anyway; you could put it to use, and if necessary, modify the roof, letting the drivers live up under decorative ...

A happy new year to all,,,,Your electricle mains box is most impressive,,But keep your fingers out of there..Or you will have a "short" year...I love the JBL Array 1400 Hard to beat,,unless you have EverestII.....

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...

Are there any current sources for large horns available in the USA or that can ship here, I have always done Array speakers and I want to jump into the horns arena but finding large diameter horns is a challenge....

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...

Here is pretty much the idea that I had – a very tall line array with min footprint and with more of less corrected timing error by angling the front baffle. At the picture below the curvature of positioning of Macondo channels is not depicted (for s...

I liked your previous post . A week ago I repaired old Telefunken tube radio (Single EL84 with array of alnico speakers ) with FM band and I'm listening to classical public radio for whole week. Not even once I had desire to turn on "big" system I'm ...

All below is written by Thomas Dunker
Yeah, "sound consistent independent of signal level" is a very precise way to sum up my whole speaker philosophy. Anything that is assumed to be constant, but which actually changes with signal dynamics is what ...

Yes indeed. The company was originally Nova Physics and appears to have been sold on to Sam Laufer, a lawyer by profession originally who brought in Mark Porzilli of Melos and Pipedreams fame. I do not know if this company actually manufactures or se...

Yep, thanks.
I still do not know why you feel that I will not exploit the “ringy dustcaps” on the Malaysian bass drivers; in fact I never gave up on this idea. I preliminary concluded that my MF channel might not go lower then 700Hz but I did not sa...

Lately I have been thinking a lot, trying figure out what I
am and where I would like to go with Macondo. The Macondo base, the horns isle
is still there and I have no motivation to change anything. The conceptualizing
and assembling of what I hav...

I wonder if it is the reactive components (blocking caps etc) that are to blame here, seeing as much of the problem is in the lower bass.Chris, what you said made me to think.

Thanks for the kind words Romy. I am enjoying taking my time with this project and getting things just right. It sure helps when there is little development involved, just duplication more or less. Development may come later as I impose my exp...

We are closing our new house in 2 weeks and while packing
and preparing to move I am thinking about the configuration of my new playback installation.
I am debating with myself about going with sub 100Hz woofer tower as I
described above vs. intro...

I was listening recently my revived Yamaha B-2 and was thinking if it has “interesting” in bass. Coincidently this week had great influence by the celebrated contrabassoonist Susan Nigro, so I shut down Macondo and let B-2 with MiniMe to care the job...

I have to inform you with regrets that due to presumable hacker attack to my site I lost data since October 6. So, the posts you made during last 3 week are unfortunately can’t not be recovered.
Well, I have to say that it was due to the hacke...

Allo R,Not to start a pissing contest, but how are they wired (series/parallel?), and with what voltage across them? Something just can't be right; the makers spec is 88db / 2.83V, which is over 1W. Unless it's uniquely smooth room gain with the arra...

I got my IBM ThinkCentre machine and true felt in love with it. What is wonderful little box. It is very quiet as it as it is fast for what I need to do and it is just perfect size for in-system DAW. I got IceDoc external drive array and they work ve...

I was hoping it was something to do with building Tapped Horns for the low bass. Maybe because I thought Romy wrote somewhere (can't find it) that the line-array bass units were the "weakest" part of the speaker system. I keep thinkin...

We now call those modeling lamps in our big stobes. I think that the analogy is even better considering your intentions.I personally feel strongly that high sensitivity is the correct path and that small ported woofers in a MTM box will fall short of...

[quote user="Romy the Cat"]You have no idea how loaded this question. The crossover point with the MiniMe is not a tactical question but actually the very strategic question of the entire speaker, let me to explain why. The woofers that I use are fai...

Ronnie,
Arranging the driver in a line array is a fierily straight forward thing. Also be advised that the arrays will less likely work across a short wall, and you need to use a long wall. Generally it is imposable to advise anything as any rooms a...
