Similar to the famous sexist tail that women can be only ether pretty or smart the midbass horns unfortunately behave in the very same way: they can be only nicely placed in a room or they can sound good. You want the horn to place in a specific ...

It is not surprising that the subject of horn is as screwed as the subject of drivers. It is understandable as driver must be made for specific horn loading, not one make drivers properly, so what the horns are made for?
A horn is a very simple dev...

Ronnie,
I’m sorry I was not able to detect the clipping you were taking about listening your file. However, if you can hear ANYTHING distorted at 1kHz (when ONLY your upper bass horn is playing) then you might consider the following: it has NOTHING ...

I need to give it to you and I need to retract my comments
about your bass pipes. I did find them to be ugly in your prototype drowning
but assembled I find them look very present, in fact quite wonderful. Connection al, of then in parallel is goo...

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...

[quote user="rowuk"]Amir,In live music, we have intermodulation. Two trumpets or a trumpet and oboe playing together create sum and difference tones that change depending on pitch interval for instance. For music in major keys, this intermodulati...

Anthony,
Yes, this is the exact configuration that I have. As you drive your LF channels down, probably it will be 30-35Hz with >2 order filter you will like the sound from them even more. I hope you have a good ...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...

Haralanov,
Here some raw cements of my on it, without any particular order of importance….
1) Sand damping it beautiful, it is well-recognized, but you do pay cost for it, in your case the cost is space. Sand is very little compressibl...

I meat with a local gentleman who runs North Reading Engineering.
He turned out to be quite intelligent
with whom is stimulating to bounce different design ideas. We might try the K-Horn
with Vitavox drivers, which would be the same as CN-191 bas...

I meant to have this post as a separate thread in the “Playback Listing section “– the “load” of it is well-deserve it but then I decided that it would be too easy for the readers of my site. The subject of this post is well related to results of...

After a few agonizing days I think a have decided for a provisional
solution. Listening and thinking about
options on a table and my current desire to invest time and resources I went
with 6+2 direction.

Yesterday I finalized everything, made the crossovers permanent,
arranged the cables, check the phases and levels per each channel and officially
declared to my wide that the listening room setting up is over. Then as the kids

All thinking about ULF are usually centered on 3 subjects:
drivers, topology and amplification. Even though these 3 subsets very much intertwined
I still would like to talk about it separately. We do presume that we have the proper
drivers for pro...

Preamplifiers: keys to mystery – or…. how a preamp might be not only a load-driving gadget.
Years after years the preamplifiers are being a “terra incognito” of audio people. I admit that preamps are a subject of my persistent curiosity. I was alway...

Yep, indeed, it looks very nice. The 8 sections of bass line
array look visually slightly overweening but I think when you put the upper
bass horns in place it will visually balance the things out. I feel some sort
of envy to the way how you plan ...

Joe, I think I would battle it.
I would not be so certain. Mostly the SUV sized bass horns are notoriously bad sounding despite of the assurances of the system owners overwhelmed with so common in audio endowment effect. Not to mention that the Stag...
