[quote user="Jeffrey Jackson"] first, basshorns... the basshorns that I posted here some years back are my straight ~50Hz horns (my memory is fading)... they are 8' long... then rear chamber.. mouth ~ 3' x 4'... throat ~8" x 8"... rear chambers of va...

Paul, l I have written about it somewhere: the passive speaker-level crossovers on bass channels are no good. Marko has 250Hz that with 3rd order would be around 10mH and 2mH. With air core then would be very large coils with huge amount of DCR – ver...

Hello again Romy and cats... sorry so slow in replying to this thread... the recent posts generated an automatic email reminder... :^)so a few things... one, there is a pair of Goto 370 on eBay and pictures of insides... the newer ones are made the s...

The fullrange Milq will be built in an oversized chassis with the intention of adding maybe two or more channels down the track and perhaps some line level crossovers. So I will up spec. the mains transformers so they can handle a larger draw and wi...

These were my first high end speakers purchased in 1980. They have been sitting in my basement for about 30 years as I've gone through everything from VMPS super tower 2 ar's to B&W 800 to my self built Edgar horns, which I’ve been using for abou...

[quote user="drdna"] Actually, I believe they can be tailor made to your exact specifications, which at that price they should be.[/quote]
It is not a thread about cup but I still….
This is always an interesting question to me – where is the thres...

[quote user="drdna"] I know all the compromises involved with the EdgarHorns, I have heard them when I visited Bruce Edgar in Gardena, and they were pretty good compared to most of what is out there. I realized that I would likely never be able...

[quote user="drdna"] 1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which is based initially on a single-driver type backloaded horn. To me this suggested that the seller was seeking the benefit...

RomanThe main point is that I like the Bass SET aproach with LF capable transformers and have a potent SET to properly drive whole band and take the amp out of equasion in the future when I learn how to build horn speakers. The system I have is an ac...

This is very complex question and since you ask too generic question I would not feel that any answer is warranted. Generally you would never have the right decay in playback system as you will get 1.5 sec of reverberation time at 50Hz in 3000-5000 s...

I except suggestions and critique. I live in Turkey and I am not living in a city, I live at the coast. It is not possible for me to go and experience most of the stuff first hand. There is no one really interested in horns or have multi-way horn sys...

... my only experience with newer, expensive Berillium diaphragm Goto drivers, has been a mix between "Wow, I'm listening to a +35K euros speakers system" and... "Gosh, music do not sound this way"... this of course was due to some crossovers tuning ...

agreed with your comments about the show. I go mainly for the record shopping as the local record stores bring out their better records. I picked up several excellent box sets, including Webern and Bruckner coral music. I also went to see the Airforc...

Somehow I massacered the formatting of the last reply. The past days I was listening to the speakers in every imaginable configuration. Sometimes I based my changes on "accepted theory" of crossovers and math, other times I just made...

The first top graph is what I could obtain using active crossovers for the amplitude and the second top moving the drivers back and forth for impulse response. The after graph(bottom) shows what the Trinnov can do.The third graph shows what it does f...

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 have just little bump at minus...

"self-matching input impedance "Aren't they trying to say the input is grounded? It sounds like they're using the current signal from cart, not voltage. Like the 47 Labs stuff. This concept has merit, but I never tried it. To ...
|

Thanks, twogoodears. I do not particular care about the frequencies cut-offs as I do not know the ALE drivers. If I speak with the system owner in context of what you say then I would post 3 questions: 1) What specific limitation or shortcoming of...

lately I've come to theorize that the horn midbass may be a contadictive dead end approach. The reason is that proper horn midbass (lets say 80 to 400Hz) will be a big one and present a few inherent "brick walls". It will physically shade the midrang...

Mumford,
Let clear first with terminology. You post said about “Incorporating active crossovers into DSET” and I think it is not what you are interested; at least it is not what I am practicing. An active crossover implies a use a dedicated active s...

Romy, I understand that at some stage you trialled a number of different capacitors and settled upon Electrocube 950B/D not necessarily for the Melquiades but perhaps for some other project. I was wondering if you ever experimented with different co...

It is wonderful how these forums work and how it's members provide the feedback and comments from their experiences and expertise.I am 90% convinced that the DEQX will not provide the magic spatial sound that I am looking for with the Edgarhorns....

The least offensive result I have gotten from a ported speaker was closest to the yellow option. I built a pair of small monitors with ports on the top purely because it was the only way they would fit. I cannot reasonably e...

Confirming our concern about digital crossovers, by Harman international, the parent co. of DBX, today at 11am, and I will quote, "theoretically they compress the sound" and also I will quote, "it is a concern for live recording and not live sound". ...

Ok, the Injection Channel project is over. I dumped the boxes not heavily and very conventionally, painted them, installed the drivers and crossovers. Sure, before I put the injection channels into the Macondo frame I flipped them upside down and tri...

Well, I do not know what should be hurtful in it. Bruce does have an idiosyncratic clientele and the absolute majority of them are heavily Morono-inclined. I told it to Bruce but he himself is not a fool and he knows it very well without my ass...

Thanks Romy.Sounds like tweeter on top will be best approach in my situation.The room is a good size and shape - 23ft x 15ft with 9ft ceiling . Plenty of room above.As you say the 288 on Azura does go to 12-13k OK with some beaming - almost enough re...

The idea of two (or more) differing drivers covering the same range is intellectually very attractive with respect to tone, and maybe efficiency, as well. OTOH, the problem remains that very few drivers sound seriously good across the board over mo...
