[quote user="ulf"]One advantage of the use of a phase plug in a midbass horn is that it will beam less at higher frequenzies than a horn without phase plug. If the phase plug is designed for the specific horn and driver it will help "steer" the HF.

TAD ET-703 LinkMAGNETIC
CIRCUIT. A high-energy, rare-earth cobalt magnet is used in the
magnetic circuit that, together with powerful soft iron for the pole
yoke and plate, provides a high magnetic flux density of 20,000G. ...

[quote user="Paul S"]Scott, is it your specific aim to configure an enclosure to "effectively" lower driver Fs? While this, along with an exponential increase in power, is a proven strategy for generating ULF, it seems like this approach creates more...

Yep, the IB sub does it's job, as I expected because I had an IB sub in my previous listening room. I think you will really like the bass of this configuration because from my past experience -- there is nothing as good as IB sub for low bass, for lo...

Hi Romy, Many thanks for replying. I do not want to modify the two drivers. I agree with about all the BS from people selling speakers with TAD drivers. What I want to do is replace the crossover with one of higher grade parts and thereby also elimin...

[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...

Romy,
I often note that you describe TAD compression drivers as being not to your taste. Could you tell us which of their range of drive units you have direct experience of and on what horns?
With regards to value for money, no such thing exist...

[quote user="el`Ol"]If everything in a recording / playback chain was clean in the sense of not polluting at all what comes out would be the original (not in terms of soundfield reconstruction, of course) and since reality isn´t clean the result won´...

The idea of making a copy of an s2 driver also intrest me, but i have some other ideas than just copying this driver.I have been thinking to make this driver with an field coil magnet a 12 volts (using a car or camping battery) and a 250 volts versio...

[quote user="Romy the Cat"]It might be a good driver but the horn section of it is very much compromised to begin with. If I have it I would consider substituting the original TAD horn with my own spherical horn. It might be difficult as it might be ...

I left the SA8535 burning for entire day and nigh, driving it with HF “torture” signals. Interesting that the driver become much more civilized with those “alien sounds” completely evaporated. Honestly it become to sound much better… but at the...

Allo RomyOk, I managed to get my measurement setup running. Behringer ECM8000/PC soundcard kind of thing.I measured the following tweeters:Focal TLRTAD PT-R9Aurum Cantus G1Fane 5022I don't have an absolute level calibrator and I need to take time to ...

This very musical masterpiece "owns" me since my boyhood, as my mother used to listen to it, as I learned about its title getting older (without NEVER knowing who performed it); sometimes she was reading in dimmed light, a book on her laps, more ofte...

An FM broadcast of church bells from the major cathedrals around Sweden welcomed 2014. Blessed with holidays in my family's home in Dalarna, the miracle of a truly great room was granted. Built with logs in 1947, spruce floor, ceiling, and since th...

hi Dominic i made myself the same question regarding the high frequencies in the orphean horn. the reason is probably because this horn has no compression, and the horn length is not so deep, and the exit diameter is 2 inch, quit big. If you read my ...

Allo,Thanks for that - I've revisited the relevant portion of the "My playback" section and I have to say, I think I understand a lot more clearly now having a) spent time on this site and b) read the little recap in your post, which is a very cogent...

[quote user="Romy the Cat"][/quote]This is a technical post.I've made some progress on my assault on the above version of EAR 834. After hard (mostly because of my idiocy) labouring through the soldering, I've creeped to the level where I can make so...

Have you use GOTO dirver before? Have you try it with the "GOTO" recommendation? Have you listen to GOTO in your own system? If not, I suggest that you do it 1st and then draw your own opinons then. GOTO never said don't worry about alignment. T...

Coops, I think in some ways Romy is right in that modern commercial horn designs based on reference drive units do rather price themselves out of the market.
It's long been the preserve of the dedicated enthusiast and avid tweaker who is prepared ...

The cone soaking is a whole another subject all together. It is possible to make amassing changes with drivers, from taking the sound out off roof to complete killing sound. I know that effect Glycerin has to paper cone. There are hundreds of other c...

of MTM arrangement of two TAD 1201 in <100 Hz Horn ? I assume they would both work in the same frequency range . Also JBL LE8 is only 89 db driver and it doesn't look like it can take any power . Difference in efficiency within the channels would ...

[quote user="ayebee"]An observation that might only be of superficial interest to the thread: I don't think the speakers use Klangfilm woofers. The pictures are a bit grainy, but the dustcaps look far too big for the original Bionor woofers. I would ...

Moreart Most people on this site only badmouth things they don't understand. From what i have read the last few years on romy's site, there is a leader and a bunch of follower's that have no clue of audio basic's in sound reproduction. The leader j...

The reticulated foam makes a difference and that is for sure. However it does lower the output. From about 1db up to 2.5db! depending on the amount you put inside your horns. Is it transparent? It is not, as it creates and audible difference even if ...

[quote user="kodomo"]Hello AnthonyYou can see the two main problems being 70hz and 200hz in this graph. 200hz is from the floor bounce of the basshorn. I will add absorbers to the floor. The 70hz peak is from the Tad bass units sidewall reflection. T...

The EdgarHorn Titan is a very well made speaker, but I have identified in it a limitation in the midrange where the frequency response may not be ideal. This will become clear after I have analyzed the speakers with RTA.
Thinking ahead, I want to...

This is what the Cessaro sounded like last year:

It does sound like a shoping list, not my intention, I was mainly trying to address some points 3 mainly:1- You have stated before that the 2440 or 375 is a good sarting reference, so I wanted to keep that comparison point. thats why I went back t...
