They showed this speaker at the Munich High End Show last year. They did not talk about the tweeter crossover frequency. The yellow cone Fostex driver is used from the low frequency limit (they claim 32 Hz) to 250 Hz. The back loaded horn is 3.3 mete...

Per your recommmendation at your last visit, wish to try using your injection channel with the Dannoy with my horns.Are you using the tannoy only as a tweeter? If so, would you recommend my removing my tweeter and using only the tannoy's, or use both...

This is my first horn build effort. Been thinking about this since starting to build loudspeakers and finally have a listening space big enough to support a horn system. This is where I am at now, I know there are opportunities for improvement. And I...

I'm monitoring your progress constantly, so I'm well aware of your discovery. But I find it somehow a cheap trick. This is a purely irrational feeling, absolutely irrelevant for you and yoursystem. Since I have the breadboards I keep looking for a ba...

In terms of the length of the horn, I'm allowing myself a total height of 7'6" (just below the average ceiling height of 8'). In regards to the mouth diameter, that's another matter. (It appears that I will have to build two [2] different...

I believe that the Arum Cantus is typical of most ribbons in mirroring one of the principal failings of MC cartridges, a rising top end (over 20k), although I have not actually heard this - at all - with my own small Arum Cantus, and I just go n...

I got my pair of 1.5” to 250Hz trx-horns that I will be trying for my “Fundamental Channel” experiment. It will take a couple weeks to paint the thing and find out how to mount them. For a time being I have a few very interesting proposition how to c...

[quote user="Jeffrey Jackson"] I feel that the first decision when designing a horn speaker is to decide how many horns and the corresponding crossover points.. then pray that suitable drivers exist.. if not, then make them... [/quote]

[quote user="be"]I have a two horns covering from around 150Hz and up, with a crossover frequency around 700Hz, So my system is probably less sensitive than yours with the many chanels and higher crossover frequencies. But I have changed my mind and ...

That was the 4 way system designed by John Sheerin using GOTO drivers on my request. The tweeter is GOTO 160 with S3000 horn xover at 5kHz. The high mid is GOTO SG370DX with S600 horn xover at 1kHz-5kHz. The low mid is GOTO 505TT with S150 hor...

[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...

[quote user="Paul S"] Some of those Altec horns were textbook examples of both types of bell-like resonance, where the body of the horn itself resonated and certain bell-like artifacts were created/amplified by/in the horns' mouths. [/quote] Hmmmmmmm...

Recently, I added JBL 2220 for below 200 and replaced TOA DSP with Pioneer D-23 4way active crossover. The result is very positive, but there are still many issues I'd like to attend.I'll be out of country early in September so that'll be a goo...

The line level crossovers have some advantaged: they loaded into higher impedance and therefore the values of caps are smaller. Also the line level crossovers loaded against fix impedance, contrary to the speaker level and this allow writing a very e...

Ok, now it is done and it is official as I see nothing available for conceptual improvement in the crossover circuit. Interestingly this version offers the most interesting sound as well, since the circus was tune for sound, not vise-versa, it is wha...

Romy,>> getting rid of active crossover and go line-level shall give you very worthy and very predictable benefit then chasing a murky SET ideas.This is exactly what I plan to try by moving the current active filter to line level (in the amp). ...

You need to find an individual who can design series crossovers. Both JBL and Altec used these, because they sounded best. You will need to look for an individual near where you live because they will have to test the drivers as the design progresses...

Hi,[quote user="Romy the Cat"]This subject of digital crossovers became quite popular during last few years and many audio-people give up and go for a simplicity and painlessness of digital crossovering.[/quote]Well, digital X-Overs would appear to o...

Romy, I understand you are saying that a midrange horn rated flat to 300HZ should really be crossed at 600 or 1200 HZ. That claim doesn't make sense to me, esp. with a 24 db or higher crossover (active). Unless you are saying that hor...

That's one big tweeter, Romy, and, typically, it was made that big only because they intended for it to go low. I keep wondering about the effects of the extra mass, if nothing else, but also about dispersion and window blind effects ...

Dear
I know that it is very difficult to evaluate others system without a physical visit.
Still i have a very general question about the "worst crossover point".

I am quite fascinated with the result that I might get from MiniME and at the same time I am defensive with the direction it takes. Anyhow, here is how it stands…
The decision to go for MF driver was I think right one. Even the 70-20RX tweeter has s...

I would like to pass some summarizing observations and some generalizations regarding the entire “Water Drop” project.
THE IDEA
The idea of trying to find a tweeter to compliment Macondo was a good idea. Many of you know that I was proudly declari...

[quote user="Romy the Cat"] The tweeter is sitting at 1.5K, first order. That is king of low crossover point for tweeter but it is OK. The problem that I see that with this time of the filter and a compression driver used I think the horn for th...

[quote user="Vasyachkin"]waveguides as far as i can tell are designed to equalize the power response.
for example if we are talking about a typical 2-way speaker with a 7" midbass and 1" tweeter then there will be a discontinuity in the power respo...

The Morons™ at AA’s between selling to each other what they did not like and topping each other on their shoulders came up with a subject what horn installation would be if price would be no object. The question is semi-foolish as price is never ...

[quote user="slowmotion"]Good news if the analogue stages of the DCX2496 is so bad. So the improvement of a modified unit should be worth the ekstra work, and remove some of the x-overs negative influence on the sound. Which is always good to know be...

fair enough- you're absolutely right, i didn't!it's difficult to get that perspective on sonics without legitimate guideposts-- even with a lifetime of playing and recording music, it's difficult to know what the parameters of recorded sound ar...

Very interesting company and their GAMMA model looks very promising.

It is essentially the very same Macondo idea - as I told when you go for 4-5 ways horn loaded installation then there are not a lo...

[quote user="cv"]I note you calimed a fondness for certain softdomes; looks like there are some newer scanspeaks that may have the tonal qualities of your favoured types but with higher sensitivity, which will match the Focal well. Eg: D2904 types at...
