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...

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 ...

Romy You have not done your main test yet, And you are ready to get rid of your LF array's to soon or maybe you did it and did not post it or say anything about it. The way i would troulble shoot this problem is to a test referance of 3 foot from Lf ...

Setting aside the small drivers for LF, while the rest of us have been all ga-ga about the vertical array, the pros have long since moved to the "horizotal array" for LF. Although I plan for several large drivers in large "modified IB" cabinets, I t...

When the passive radiator in question is mentioned, are we sill talking about a particular active 10" Scanspeak driver that is not hooked up to an amp? Again, the PR is always parasitic, more or less fighting with the active driver, except, apparentl...

The kids are growing up and twins sleep fine and walk already.
So, the Bessnow’s household is calming down, a live-in nanny for sure helps…
With more time at my heads I am trying to finalize my playback in our new home.
I spent a few hours today t...

Angelo,
I care less about the “commercially available” objectives, honestly it is too boring.
However, whatever you do not be distracted that what you are making will be reminding Avantgardes. The Avantgarde Trio Classic (in vertical configuration)...

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...

[quote user="cv"]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 wit...

Listening to the horns, it seems that they indeed die somewhere below 120Hz. I was surprised, and a little disappointed that it seemed so steep. Good to hear that it's to be expected!!Yes, I'm using a 30-something-Hz 1st order high pass on them ...

[quote user="Romy the Cat"]Well, it might sound as a heresy to you, but I personally
consider the impedance curve is a bit irrelevant in this application. In this application
you need to care only about only 2 things: if you have enough power in yo...

Actually it is very interesting question and I almost feel you pain for decision you will be making. I do not think that anyone would be able to express any arbitral opinion about the subject, as least an opinion that worth to follow. You see, buildi...

The 10" "woofer" is well known to "high-end" designers, who love the "fast" bass, and I have to admit that Wilson and Dunlavy (among others) have also managed to get some impressive (at least for a while...) "dynamics" from the little woofers. To lo...

[quote user="el`Ol"]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 enclosu...

[quote user="Romy the Cat"]Last night I did an interesting experiment. I took the bass towers,
just 4 driver per side, crossed them at 90Hz, line-level and drove them not
with the Milq’s bass channel but with SS Yamaha B2. I use it with the tube cr...

In MiniMe, after study all recommendations and talking with a number of port speaker manufactures I decided to go a simplest route. It will be one single port at the bottom. What pervaded me was the Precision Port Company. Then make 2” port with 4” a...

Once you figure out where you want the LF drivers you could put them in a "cabinet" of lesser dimension and run that "cabinet" through the floor, using the basement, or part of it, for more volume/IB. That could "solve" the IB footprint problem, and...

Interesting, Very interesting.
I might make some observations now, claming this recent modification as a success. The minor gain of sensitively certainly did not heart but the major advantage was defiantly the “activation of ceiling”. It is hard to ...

Here is my proposal for an ideal horn system. The concept derives from the really of the horns as I know them, the available park of the drivers, the drivers’ real capacity and from… everything else that I might comment upon if you would not figure o...

Your point about relative levels is well taken. Still, the typical concert grand piano, for instance, does about a 27 Hz fundamental, as I recall (and certain pianos go rather lower), and some other instruments are not far behind. If to simply low p...

[quote user="kodomo"]I don't think you can align the tapped horn. My tapped horn has a total length around 5 metres. To time align that with my other drivers, its got to be around 5 metres closer than others. The only other solution is delaying the r...
