Hello Romy, thanks for your guide.I've been thinking and I feel that some basic upper bass channel ideas are forming; they a result of, as you say ,"organic" derivation from the rest of my acoustic system. I am pretty excited about this idea i have. ...

[quote user="Paul S"]Murat, that's a lot to ask from one driver. [/quote]1000-12 000 is 3.5 octaves.300-3000 is a bit less.[quote]In any case, if you do get useful results with the paper driver, you will have to turn right around and integrate it bac...

Hi all
I dont know why Goto do what they do...
But if we imagine using only the - good - part of a "perfect" horn/driver combination we will find that the bandwidth will be very small.
About two octaves probably...
Think about it; most compr...

As I have mentioned previously I’m slowly in a process of assessing other opportunities for my Macondo, since the EV T350 driver it too soft to be paired with Vitavox S2. While I am doing it an old observation keep knocking in my head. A few years ag...

[quote user="rowuk"]Brass instruments function much differently than audio horns. First of all they are built extremely resonant by mismatching length and horn taper. The taper of the bell is there not for horn type efficiency, rather to change the a...

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...

To save people from researching the differences between Romy's and my systems, I'll note the principal differences here, ignoring our ongoing mid-bass projects, which will be different, but both are incomplete, so not yet in the picture.As concerns t...

Romy,
The upper bass horn has a Ceramic driver 18sound 8M400, the MF horn has an 18sound 2060A Neodymium magnet, tweeter is Beyma Ceramic driver and supertweeter is Fostex Alnico. The Leak amps are PP deep class A, we do have a...

user="anthony"]Thanks Romy. To be honest they look better in
the flesh than I had thought they would so I am very happy with them. I
think I'll make the steel order today so I can finish them at my leisure.
If I end up with 8 drivers a s...

Hi everyone,Ive been tracking this exciting conversation for some days. One from outside may think this is weird, we are making a lot of air about some sound-description without getting to the point. Im (or was) normally more rational. And if I read ...

[quote user="Romy the
Cat"] If I defeat the hardness by dropping of the output impedance then I
would understand what is going on but I minimize the hardness by raising the
output impedance!!! This is very interesting and I need to think about it ...

I understand your recommendation and agree. I need to have upper bass and MF and than see how to merge fundamental channel in between.So, I better postpone experiments with compression drivers and only compare 12" Supravox in two horns: 42Hz 2m long ...

I assembled SUN 2A3 amp for my friend and found it to be quality kit and very easy assemble. Kit was old .I think late 90's so maybe quality deteriorated since then. I have variety of 300b Czech tubes and (Eml 300b , KR 300BLX 842VHD ) bought t...

Alrhough the phasure stuff does sound very good, I do not consider it to be “the bleeding edge”. I consider a preamp allergy to be very typical of those “making a point” for instance! Declaring that only 0.6V sounds good on the DAC demonstrates yet m...

Sorry, Teodor, I do not know what Keele's paper has to do with anything, where I failed and what you are trying to say. The fact that I will not be hearing of you anymore will certainly help me to sleep well as I was desperately afraid that you will...

Romy,We have discussed apottted Compression Driver's before, and I would not commit to promising performance you would like. Howere, here is a place where spotted speakers might well answer your needs, without altering anything you are currently doin...

Thanks, El, an interesting driver indeed. It would be interesting to listen the thing though I have personally no use from that type of driver. Purely on the specs there are some moments that I would like to see different. The 250Hz resonance freque...

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...

No love lost for any particular driver type here. They are all all-but-hopeless, as far as I'm concerned, just for different reasons.Jesse, what I wonder is how the small daiphragm of the compression driver, with its very small movements, can b...
