If I somehow was able to recalibrate Macondo to run with the specifics of my new PP2000 sound but in the lower bass my currant playback is completely dead. It is not that it is non-listenable –it is enjoyable but the whole lower end of the midbass ch...

Rakesh, I think you take it all wrong and I think you need to perform some degaussing from my site. You created for yourself a cardboard cutout of ideas that I describe at my site but it is not what it is. Macondo Axioms are not set of rules but a di...

Thanks for responding. You mention a rotary phase knob. Is this ULF system connected through a digital processor? If yes, will you expand on DSP effects on sound and system integration with the DSP? Many "pros" use these filters to "handle" speak...

Great analyses, David, thanks. I can’t concur as now with anything. Macondo in the room with midbass horn was a complex installation and with ULF it became even more complex. Some of the things I setup by ear and do not use measurements, I just know ...

The 185+W into 1 Ohm is not a lot indeed but I do not understand all of those simulations and I do not know how the distortions of simulations affect the actual results. N-set, when you are mentioned the “Romy's constraints on a powerful bass SE amp”...

[quote user="anthony"]I seem to
remember you had this sort of issue when setting up your previous room and
eventually you moved them time aligned.
The one stack of 15" and 10" sounds
like a nice solution. Do you think more 10" scanspeak instead ...

I seem to remember that we've covered somewhere the sonic benefits of SET at lower frequencies, but I guess I never really thought of ULF as "bass", per se. If someone ever comes up with an SET that can be an effective part of an AuraSound circuit, ...

I am finishing us to setup my listening room and I have my PP2000 blowing up sometimes (go to protection bypass mode) when I use powerful SS amp for ULF along with Melquiades and the rest of the systems driver from one single PP2000. So, I guess I wo...

Hm, your advice to discard the Midbass time alignment and to
go to ULF time delay to catch up with Midbass timing is very interesting. Theoretically
I have no auditable sound from ULF. They are at 20Hz. As you understand there
is no way to align t...

[quote user="noviygera"]I thought I'd let you know that I ordered four of those Aura subs. Thanks for the advice, if I receive them (I hope so), I will install them into my new listening room. This will take a while because I still have a few mon...

I did not make my mind about it but I have some “concerns”. Using SS amps and hearing different SS amps I do not like their bass and the notion of a powerful enough DSET to be able to drive ULF in A1 was born. Sounds logical. However, recently I ...

I has been thinking the whole evening about the subject of
the ULF hardness I was experiencing today and here is my leading hypothesis. I always
was pitching that a sharp order filter is a barbaric thing to do, particularly
at LF. Still, here I am...

I truly enjoy reading the different internet audio idiots expressing their “wisdom” about what I do. There is a site out there filed with typical audio white trash and they suddenly developed a desire to criticize my admiration of FM based upon ...

Since my B2 ULF power amp will be long time to fix then being a compulsive person fully suffering from Dostoevsky Complex I bought another B2 amp to keep the blood flooding in my playback. Surprisingly it was no my decision but I got advise from ...

It looks to me that I will be able to live with my 6 driver
line array. Again no measurements were made but it is what it “looks”. Sound-wise it is very reputable and I just might
leave it as is. My current room is 6 larger to what I had in downto...

It was as a year with a 2 major of audio events: New listening room, New Midbass horns, New ULF channel. It took almost 6 months to get any more or less reasonable sound in my new listening room, not that I was working so long on the room but rather ...

Albert, the Adjustable Hydraulic Dampening might be effective if the vibration of floor is the factor. This is exactly what I question as I do not feel that the floor vibration is a problem. Considering the length of the waves and the amplitude of t...

[quote user="Romy the Cat"]Scooter, I wonder how many people among those who propose those modifications do understand what they deal with when we are taking about a more or less properly reproduced sub 30Hz signal. It sounds like arrogant comment, n...

What I heard in your room on Saturday was superb reproduction of what was recorded from 40 Hz. up. This is ideal probably for a recording of a chamber group in a small hall without anybody present. One could hear the hall surroundings which replaced ...

The ideal horn system would have to be well integrated into the room, acoustically as well as optically/cosmetically. As far as a commercial venture goes, I believe that Marc Henrys "La Grand Castine" was already (except for the ULF dipole panel) ver...

In this case, below 50Hz, I think el`Ol is right to suggest that you consider using DSP as a permanent solution. The SMS 1 is in theory the silver bullet... You just need to find out if you can live with it long-term. Best way to find out... Plac...

Very, nice thanks, ulf.
I never heard this company and it is good the more horny newcomers pop up her and there. The epoxy carbon-kevlar and glass fibers staffed with damping? I wonder how more fun would be if they staff these hollow horns with sand...

A guy visited me today and while I was playing to him some music an ides stroke me: how to make ULF channels invisible? I have given birth to a ridicules ides to make huge, 40hz, no-cheating horns in time-aligned position absolutely invisible in list...

... as I also found something VERY similar, Roman... the truth is in the sentence "... bass-shy in full range..." as a full-range cable is equalized for 20-20khz and - you'll agree on this - the ULF frequencies of your system aren't so common, around...

This is kind of funny. I got another B2 amp a few days back. It was near new condition, at least inside. As I plug it to drive my ULF I felt that it produces some kind of strange bass. I did not like it at all and it was very different then what ...
