[quote user="miab"]I had a dac that took 10 months, a turntable bearing a year and two compression drivers that took almost three years to arrive. All of them had me wanting to give up on them but persevered for the goal. I have spoken to Damien and ...

Hello Romy,Which other output tubes have you considered? I researched ‘suitable’ output tubes to drive tweets a while back for compression drivers [Be domes] — but not phenolic domes. Reading of your results with the EV tweet reminded me of how sweet...

[quote user="ShuffleSk8Ter"]there is one system that resembles what live music sounds like and its not a horn! To be honest I really have no idea of what topology these horns were setup like... all i have evaluated is there soundI like to go into som...

Do proper horns "suffer" from K2? Do you not think that the back chamber loading is part of the engineered concept? Are you sure that reflections from the room that travel through the horn to the diaphragm would not cause more trouble? How can yo...

My work to make the Fane S 8m work, continues amd I have yet to hear my midbasshorn built perferctly according to Romy-specifications. I will continue because in early trials there was something I did like. I guess I will just end up with a measly €...

I do have a speaker with a flat impedance. It is an Apogee Caliper Signature with an impedance variation from 3 to about 4.5 ohms over the whole range. Fortuneately it is not so dead as your example as it has about 86db sensitivity. ...

Allo Romy, I have no idea about the above - my gut feeling is that the required thickness of material would be too great, still, I bow to your experience in S2 mods. I just wanted to mention something that came to mind that might be of interest: I re...

Hi Romy,Your the first person that I have seen that seems to have actually made PP tube amps work with compression horn drivers. It has been my experience that PP amps don't like the low watt operating range. I supose it all is a matter o...

[quote user="jessie.dazzle"]Romy, I'm very pleased to learn that you've got your Injection Channel done. I assume the above illustration is not indicative of the way you have the Tannoy Red aligned with regard to the other drivers, as it appears to b...

[quote user="Lbjefferies7"] I would like to ask a question. Does the Jubilee add a specific color signature, or does it change appropriately with the music it plays? [/quote] To make it brief. I do not think that it is warranted to talk about “Jubile...

[quote user="manisandher"]I received my copy of 'The Karp Segall Experiment' today. The music's not really 'my cup of tea', but it's OK as background music for me. Using RME's Digicheck, I'm measuring -50dB noise at 81KHz... [/quote]What was the RMS ...

Romy Hi, Raplh uses a 300b push pull, but the power supplies are massive, parts alone 15K Euros, each channel has a separate supply, the pre-amp again two massive power supplies , he prefers to use eight of the horn loaded bass bins, although I...

Kerry, thank you for sharing your paper diaphragm idea. Very interesting. As I remember it, the Cogent diaphragm I saw (and listened to) at Steve and Rich's place was a flat disc of something like fiberglass, and it looked relatively heavy for the ap...

Romy, if you have some spare diaphragm/VC assemblies for your S2 drivers, do the experiment I mentioned above (remove the outer layer of the VC) and we will talk about the inductance in terms of sound after you hear the results with your own ears... ...

Thanks Romy, I'm using a TAD 10" mid in a sealed box to produce 200hz-800hz. Although I'm fairly happy with it, I'm hoping a compression driver/horn would give even better results. There aren't a lot of ready made options for 200-800hz so I chose Got...

Hello Marc Henry,I am curious as to why you picked the 4540 driver for HF. I have no experience with this unit but it is interesting since the design claims to be of the "ring-radiator" type. This topology was invented by Steen Duelund for use in reg...

First off, I will point out that neither Silbatone nor I claim or agree that the Aporia horn is a point source, because clearly it is not. The sound comes from two "areas" but even that is not a particularly useful notion.Although some do make that c...

[quote user="CO"] May i ask if you have ever played with the Le Cleach flares and how you find them?They were created to reduce reflections directly back into the horn. Only problem is they are very large because of this.... [/quote]

Robert, what I meant is following: when you will be collecting requirements for you own drivers specification and will evaluate the implementation methods then you need to have you own identity what you are trying to do. I might post a lot of differe...

de Charlus, I still do not think that there is such a thing as “ the only a theoretical starting point”. Perhaps you were inspired by Jeffrey’s recommendation that has more experience in it then you. Still, the compression drivers loaded into giv...
