[quote user="Romy the Cat"][/quote]Ok, here are some thoughts that I have after the last night experiments. The tests were made with Sunfire subwoofer, wiath is bad sounding machine but excellent LF test source. The Sunfire slope wary from 3rd order...

[quote user="Romy the Cat"]Guys, I am not looking or care about the design specifics but rather looking for some fresh idea and inspirations that would make me to think further. You see, if I shut down Macondo and measure just ULF channels then I...

[quote user="jessie.dazzle"] Have you tried taking a measurement with the line arrays moved to the rear of the room? (ideally, he same as the current distance from the listening point, but behind you). [/quote]As I said I moved them everywhere.[q...

It has been a while since I heard any Velodyne subs. Do they change models annually, like everyone else? Whatever; they have been around for a long time, and I have heard many of them over the years, including several of the Stereophile Recommended...

[quote user="Romy the Cat"]So, what I am talking about is ability for an amp to have some kind of inner-algorithm that dynamically and actively “color” or better to say “dye” signals, still maintaining general color-neutral tendencies. Since I ...

Hi Romy and Company:
My CD player has seen better days so I did some research and though you might be interested in my experience with the "Music server" concept. Punchline: fun, sounds great and is very convenient!
You can create your own aud...

Maybe this is a mic problem, or a Sunfire problem. But, like I said way back when, the raised floor sink is not only the 5 Hz structural/footfall resonance, but it is uneven broadband + & - with respect to hi-fi, and the helluvit is that your ho...

Hi Romy,
Sunfire? No! Who would add a Sunfire to this system? The black box in the pictures a power amplifier for the midbass horn.
A second MF could be interesting. I will see if we can do some test set up of this. Per has the space for it...

[quote user="Romy the Cat"]Anyhow, I did the measurements today and what I saw shocked me. Of the ULF sections has nice 20Hz at MF level then they have +12dB at 60Hz level. That explains everything but it also absolutely clearly indicates that the se...

user="ArmAlex"] Hi Romy, In this picture it looks that attic
opening's distance to listening position is very close to distance of chair to
the main speakers. Time alignment?[/quote]ArmAlex, very good question.

The last night I “locked” Thomas to watch Masha and Bear in
my office and spent some time with playback trying to answers a few questions in
my head.
First, I needed to discover what was the source of the ridicules
double-sound that I exp...

I have been lurking here for a while and am fascinated at the discussions of TONE. I play trumpet professionally in Germany and have many opportunities to experience big rooms and big pipe organs as well as symphony halls with various degrees of acou...

One shall not be Nostradamus to be able to foresee that I would religiously appose to this approach for playback evaluation. I do understand why Harman would love it as it creates a sales tolls and the sales rationalization but it has absolutely...

There is site out dedicated it infinite baffles subwoofers. I am not sure how serious they are as they use mostly metal in rubber drivers as got thrilled when “Apollo 13 takeoff, my doors move back and forth 1/2", and the frequency is below 5 hz...

[quote user="Paul S"] Given speakers that can be driven dynamically by single stage amplification, there remain a host of issues, and among those issues is color. Most compression drivers are color-challenged to begin with…[/quote]

Adrian,
You pretty much said it but do not think that what you said it minor – it is in fact huge, with exception of some rough lathe-work: it is not exactly true but if it was true then it would be irrelevant to Sound.
I really do not know wha...

[quote user="jessie.dazzle"] I have 2 ULF "boxes"; each has an 18" McCauley 6174.
The enclosures are sealed and each measures 14 cubic feet. They are made from 70mm thick concrete blocks.
Power is from a pair of M1.1 amps (100 Watts each)....

It is very good that you put your midbasd chenal behind you listening position. If they are time line then it is at very very cool solution. It gives a very interesting and very beneficial space confusion. And in this case confusion is a ve...

My Placete preamp was sitting in Idaho for update for a
long time, so there was not a lot of audio activity lately. Also, the last few
month there was a lot of things going on in my life that severely compromised my
audio rotation. It is summer an...

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...
