These are 103db efficient 15" midbass boxes. It's a band pass horn design with narrow bandwidth of 60-250hz. No port thought, it's a sealed box with two chambers in front of the driver. I do not know how they sound but, myself interested in trying th...

This weekend wife told me that I should not do nothing else
but to fix my playback and this was exactly what I wanted to do. Yesterday I took
good 14 hours to play with it, moving boxes, trying to find a good
configuration, making measurements, th...

W,
Be careful with Milq’s LF channel. When you go for a dedicated LF SET and make the SET to operate very low then you need very precisely dial in the loading of your out tube with the behavior of your LF drivers/enclosure. Without know the very spe...

[quote user="Romy the Cat"]Again, it was very interesting, but… Let agree that methodologically you did not try Placette as it performance was masked out by you need to use your Neurochrome buffer to get gain. Your chain will sound as the worst eleme...

This is classical common mode noise interference on a common supply. This type of noise will pass right through any power conversion technology and in both directions. Due to the timing variations, I would expect it to be a little bit of mains inte...

I am using the Celestion Axi-periodic compression driver in the KLIPSCH K402 horn which I have boosted considerably when I noticed that the top one and one-half octaves were barely working when playing music so I figured WHY NOT? and it works just f...

[quote user="Paul
S"]If you said anything about your 15" VitaVox in the video, I
must have missed it. What frequency range are you running them, and what
is low-pass filter? Given your prejudices, I suppose the cabinets are sealed,
so they can't...

I spent many hours listening and experimenting, trying to change the signature of my mid-base channel. Everything that I'm trying suggest me that I am in at very right direction but I am still not server I would say freeze the system and do not t...

Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from being best for the 6C33C...

Mani,
I would leave the subject of DSET/horn setup for another thread and would drop a few words about Zu Druids. They are not the speakers that I would ordinary comment but since I have a local guy with Zu Druids and I had a chance to hear th...

Oh, rowuk, you have no idea how much I agree. To me passive theaters very much like ports and I hated anything which stay even remotely close to it. However, this time the entire Remedios project is is very different s s is built not based upon knowl...

I though this would be answered elsewhere (AA) but Bruce Edgar did not reply. This question is important for me, maybe someone can help.When running an impedance sweep on the Edgar 80Hz horn some serious bumps showed up. (I ran the sweep because it s...

Hm,… yes and no. Inductance is not necessary an evil. Well, it is an evil for open-top-end drivers but you need to look at the life of compression driver all around and then you understand that inductance is not limiting evil. Sure with grow of diame...

I know many would view the two frequencies as similar and perhaps of little consequence, but I have my reasons.My primary, driving objective for wanting the horn to produce sound faithfully to at least 90Hz is that 90Hz represents an ideal crossover ...

[quote user="nl"] Within that horn-loaded range, the 210/515 type combo does reasonably well, and produces rather more inspirational midbass than most direct-radiator type strategies. There is a reason why these designs persisted for roughly forty ye...

Despite the tremendous popularity of the single-ended amplifiers have a certain group of audio people, let to be honest: the SETs do not sound REAL in audio people’s listening rooms. I was in many of those listening rooms and have heard many best SET...

Ronny, it is funny because I was juts about to carve my further observations about the Sound of my monitors. Last night I was listening Rigoletto by Callas and Gobbi on my monitor. I come to an interesting observation that I would like Monitors...

Well, Nerone, the differences between any tuners would greatly vary with signal, not even with the strength of signal but rather with the specific location and surrounding of a given station. To make the things conceptually right it wou...

Yes, it turned out to be the emails from GOTO importer. I am not completely understood if the horn at the picture above is an official GOTO product. The Ming Su said that the horn was build locally by Jeffrey Jackson with the support of GOTO but then...

Romy, make you own very simple experiment and then make your own mind.
Take two horn channels, low-pass and high-pas them at 6K for instance
and drive them with 6K sinewave. When you time alight the driver you

I have been playing around with speakers for a long time, and things started snapping when I got into horns. I have a system right now with an upperbass horn from 140 hz turned form MDF up to around 700 hz, to another horn, and another and a super t...

I do not advocate injector
on the ground. The way how I use my injector I high pass is aggressively, so the
ground coupling is not a requirement. If somebody use injection at lower
octaves then it might be a merit to do so but not in context of my...

I wish I could stop the US government from selling AK47s in any corner shop in the US. If you give a monkey a gun, most probably he will shoot himself. If you give a monkey an AK47, well that is different. He will take anything he wants and few thi...

[quote user="Romy the Cat"] It is in a way ridicules. For years people who build of use horn fight with honk in horn, particularly in midbass-upperbass-lowerMF horns. I built my midbass horns and it has no honk, I mean no honk ever of any kind. S...

Hello Macman,Nice horns, I like that you finished everything properly! I am getting tired of seeing piles of horns.I think the ringing you are getting from your midbass horn is that the throat reactance is not balanced. How did you calculate the ba...

[quote user="Rewind"]Hi, I am slowly building my own Macondo. I understand why the injection channel is there. It brings some kind of softness that the compression drivers lack. [/quote] OK, but it is not how I feel about the service of injection...
