Thanks Gregm. It is interesting that I completely forgot the TAD PT-R9. I was looking at it 5-6 years back and spoke with AudioKinesis ‘Duke, who reportedly knows them well. My reservations that time were the very same as now: with 97.5 dB/W sensitiv...

We understand that Charlus’ selection of drivers are not a selection yet but some kind of very preliminary idea of the drivers that he feels like he like. I said “he feels like he like” not accidently. I do not think Charlus, or anybody else in h...

Reinhard and Kaluss in Germany has been playing around with the Goto bass drivers for a while.[/quote]Thank you for the link!I'm completely with this s...

ltsv38, it is an interesting solution for lower midrange horn. If I use something like this for Macondo ‘s fundamental channel (but of cause spherical) then I would flip the horn with driver up and run the neck longer to accommodate a slower, expone...

"Sadurni Acoustics' Staccato 4-way hornspeaker exploits MDF horns with up to 3" wall thickness. The 92cm lower midrange horn which loads a cone driver can "achieve 100Hz in-room". The actual 'turbine-horn' midrange driver is a compression sort. "The ...
|
One of the main advantages of Macondo configuration was the fact of multi amplification. As with any other systems which have a dedicated amplifier of the same type to each individual driver Macondo can run over dynamic range with amazing ease th...

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...

They have a 17cm throats so in most cases it is better to get the version with 2" throat for compression drivers, shorten them for the right throat size and build a chamber yourself....
|
Sorry I misread, I thought you endorsed the use of PP tube amps with compression horn drivers. Well it looks like were still in the same situation of not making them work. I could go on about why I feel they don't work, but it won't chang...

[quote user="RonyWeissman"]The electricity comment is interesting as today I put on some jazz music and the HF is very snappy, excellent! I feel like posting on AA to ask people's opinons if it's the electricity or if my concrete horns are going thro...

Romy Hi, I do not know how the Alphas are configured crossover wise or how much 'sonic mad' they use, Avantgardes do not use compression drivers of course just slightly modified conventional cones ( I believe ) I have heard AG Trios the Cessaros are ...
|
If you ask me the compression drivers is like the jbl 2420/2470 design only with an other back chamber. And the low freq driver really makes me think of an old alnico driver of jbl 2220A http://www.lansingheritage.org/images/jbl/specs/pro-comp/2420/p...
|
I've been thinking about this matter for a while but could not find a better excuse to formulate my theory then in this topic. My simple theory is that if we reduce our concept of "music" the more fundamental concept of "sound" as point of reference ...
|
[quote user="msaudio"]If you look at the picture second from the the top, you will see 2 woofers mounted in front on the baffle, notice a 2 piece horn from the baffle. Klangfilm never had such a horn, they would start at the baffle and curve out. The...
|
There are a few at least theoretical backdraws for the Array in my view.Of course having a lot of different drivers playing at the same frequency implies that all of them should work in perfect unison, if one starts lagging a little bit it will mess...
|
I take it back, 100Hz is pushing it regarding horns and compression drivers I know of. I can't imagine a compression driver reaching the midbass muscle of the Fane S 8M. And I don't see why one should try, when the Fane reaches 120Hz so effortlessly....

[quote user="Jorge"]I tend to like drivers with plastic suspension. Radian makes retrofit diaphragms for JBL with plastic suspension, maybe they will help you achieve the tone you are looking for.
Extensions are easy to machine out of aluminum, eve...
|
Hm…m… I do not know how about that.
Well, the SG146XX
where the most interesting from one perspective and the most problematic from
another perspective. Goto, never gave to SG146 an option to moderate resonance
frequency and without it I feel i...

[quote user="coops"]Ralph and Thomas are friends there would have been no price premium for the field coil option …[/quote]Considering that Cessaro claims that they pay for $500 worth TAD drivers (OEM) over $5000 then I might only imagine how much pr...
|
Ralph (Cessaro) is in the process of manufacturing his own compression drivers, I have no details as yet, I believe the diaphragms will be beryllium not made by TAD.Also new and ready for release ,although not shown at Munich are double skinned carb...
|
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...
|
Decoud, I do reject any speculations about flux modulation in compression drivers as I do presume that it is absolutely negligible. It is like using a SS amp with ultra low output impedance, to drive a ribbon tweeter and to worry about return current...
|
[quote user="Romy the Cat"]It is was not bad sound but the sound that clearly indicated that something is very wrong: supper compressed, complete absent of LF, huge HF extension. The whole horn sounds like a bad MD driver.[/quote]Open the back panels...
|
[quote user="oxric"] So, yes, in an ideal world, I would have seriously considered doing something different….[/quote] I guess your definition of “doing something different” would imply reading of 534 pages of BS from people who have no idea about ...
|
I'm mainly concerned about three things: 1) I know I'm using the larger compression driver outside (below) its designed operating range, and it may not work well there, although just band-passing it in this range, and using it at reduced volume witho...
|
Stefano, I do not exactly follow what you tried to say but it is OK. We do need to understand that we do when we are talking about Goto or any other driver manufactures. It is absolutely not know what the hell sound comes in your drivers. I hardly be...
|
[quote user="mats"]I have found the T90A to be reasonably in-offensive with JBL 2435 Neo/Be compression drivers. I use them with relatively small caps, currently 0,3uF. The effect is a welcoming of a higher frequency palette that to my ears does not ...
|
[quote user="MINGSU"] I finally received the GOTO SG38WNS 15" woofer and GOTO SG188S tweeter this week. My next step is to build a dual driver bass cabinet to cover 70Hz down. [/quote] Ming, I know nothing about the Goto woofer. Would you care to sha...
|
The $3.6K per pair, if they are good divers - the 2440 level, is a tolerable price for custom-made drivers. I presume that he does not include and PS into the price. My major question would not be about the drivers – the filed-coils are very simple d...

I never heard it or about it but here is data:

It looks like it has CB horn and aluminum cone in pl...
