The above in Red color the response of Tannoy 10” Red

position of third driver and loaded to 4th 25W/8565-00 driver as passive radiator.

What might be very interesting also is to learn what DC coupling in power amps would do generally in term of Sound.
The first time I thought about it was a few years back when ...

[quote user="jessie.dazzle"] For a lot of reasons, I'd vote for an alternate placement. You've got that basement, so why not use it as a rear chamber? You might be able to use the volume "as is", without building a proper rear chamber. In this ca...

Looks fine, Anthony. I am not sure what resonance frequency tells
you. Anyhow, a great advantage of your pipe topology for LF is that you will be
able to pile up as many drivers as you need in order to hit the desired
reference DB level. There is...

Cessaro ALPHA:
TAD TD-4001 2" driver on tractrix horn with 56cm bell (approximately 250Hz). TAD claims response from 600-20KHz. Given that the midbass is essentially a direct radiator (theref...

[quote user="anthony"]This is excellent
information Romy. I have been worried about crossing the woofers at 100Hz
and would be much happier if I was able to cross them lower. We will see
how everything integrates into the room and if I do need t...

[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 ...

Loudspeakers. For whomever who follows my dairies on this site and whoever has any real understanding what makes a horn-loaded loudspeaker to sound good it is know that Macondo Acoustic System is not juts the result of my DIY efforts or the John Hasq...

This is very interesting observation. I am in away envy that Petar went for a set of large woofers (4x23”!). This is the way to go! Unfortunately I did not experiment with it even I had the drivers and means to do it. My problem was with the fact...

Yes, you are absolutely right.
If I make a much deeper cabinet and put many more drivers closer to each other
then I will have much more sensitive array. I do have 18 more of those drivers
and the idea did hit my mind. From what I have now an extr...

This weekend I was walking in my new listening room and did
some thinking how to organize everything. Unquestionably my first step would be
convers Milq LF section (bass line-array) from Midas accommodation to drive my woofer

This post is a logical continuation of the post: My “radar of sensations” about the “good honk”:

Well, I kind of begin to think what kind LF solution I might
have in the new room. The ULF might be fun to load on the ceiling in the way
how I described above. For the midbass I most likely will go for the
line-arrays with my beloved Scan Speak 2...

It took for me a few weeks
to put up a new direct radiator Midbass channels. Each channel has 2 of Vitavox

Many people know that I run a side business doing wedding photography. During the 24 years that I have been doing the wedding gigs, and after over 950 jobs that I went through I kind of have seen all imaginable wedding bands. Certainly the “events mu...

I made today some interesting experiment and for the first time during my “fundamentals channel saga” I get some stimulating and very result. I find a way to mount the “low frequencied S2 driver” on the speaker’s axe way above the Macondo’s tweeter. ...

That is a fancy one, with vacuum caps as I can see it. I do
not know about the practicality of vacuum caps – they have own pluses and minuses.
Still, that is nice crossover, a bit more complicated then I initially thought I
has to be. It would be ...

There are many threads on my site where I covered the subjects of Tweeter for my Macondo and particularly the moment of integration the tweeters with Vitavox S2 compression driver. Since a few months ago I altered my idea to use the EV T-350 tweeter ...

The exceptional 15-inchers would be two fitted in two categories: the bass 15-inchers and wide-range 15-inchers. It is imposable to think about the exceptional and wide -range 15-inchers and do not mention the 1946 -1973 production of the Tannoy Dual...

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...

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...

This weekend wife told me that I should not do nothing else

good 14 hours to play with it, moving boxes, trying to find a good

[quote user="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]

Dear Romy, regarding your efforts to solve variations in mains power supply, there has been an interesting thread on RAT related to the use of toroids as power transformers that morphed into a discussion about the level of DC offset in mains power su...

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="Murataltuev"] I understand all
disadvantages going digital.
I strongly believe that minimal influence to the signal is the most important
aspect. And influences in digital domain are usually terrible. But I'm not sure

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 ...

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
