[quote user="manisandher"] Did you ever try this?[/quote] Nope, I do not yet but I know people who did and who report very positive results. I think there are even some commercial companies who did it. I spoke with Lavry people, trying to commission ...

Anthony, I agree with your central observation, and I have used paralleled HF drivers for decades, starting with the old Peerless paper tweeters paired with RTR6 electrostatic arrays, and now paper whizzers with Audaphon ribbons. As you know, this ca...

[quote user="Paul S"]Romy, I am on the verge of an L-pad for my HF ribbons, but in my case I believe it is mostly the MC cartridge response I am wanting to offset, on a case by case basis. [/quote] Hm, this it VERY bad. Fix you cartridge setup, it's ...

It is the "Big'Un", high-passed at 110Hz if I remember what he said correctly. The tweeters are back in the main driver frame with some EQ added. I'm sure the effect I heard came from the combination of the driver and the cabinet. So ...

HI Romy, thanks for the thoughtful reply. 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...

I'm not sure what relevance the purpose something was created for has to whether it can be used in a serious audio system. As you point out elsewhere there are many products created which are supposedly for serious audio use which are...

I always thought there are only two basically interesting approaches to the sound reproduction:- eliminating the room effect as much as possible with a controlled disperssion of a forward firing horn- or completely include room (a bogus idea, I know)...

[quote user="gordan"]I didn't explain the context of S3 use in my future system. I'm awaiting for a delivery of Beyma TPL-150 which will be tested for upper mid channel, under either Raal Lazy or Fostex T825 tweeters. [/quote]I am not sure that I agr...

Interning as I again feel a need to use a pilot system with my playback. Not that I “need to” but I rather fine it very comfortable as playing digital strip from multiple locations I have music running for many hours. I have not too high demand for q...

Audio people love to argue which tweeter is better. Living aside some semi-objective technical aspects I would suggest that the debate about the advantages of one tweeter over another without referents to anything else is completely bogus. A tweeter ...

Josh, I also loved my old RTR HF 'stat arrays, doubled over old Peerless tweeters, but I sold all that Fulton stuff to Dr. Dynaco several years ago. My idea for the 'stats and the ribbons is that I do not depend on them for tone but use them only ab...

[quote user="el`Ol"] I stopped believing in phase as the most important cause of coherence when I listened to the Lithophon Miracle and believed to hear exactly the opposite of what I am used to with cone/dome speakers: woofers that dynamically don't...

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...
|
|
[quote user="be"]"This topology was invented by Steen Duelund"Ah-hm, ring radiators where not invented or even re-invented by the Steen Duelund dude, just copied. JBL used the priciple 40 years prior to that in: 2402-2403-2404-2405 and Fostex have b...

What is sitting on floor inside of left bass radaitor? Looks like two bullet tweeters? I assume he is just putting them there for storage as there is nothing inside right channel.He must be getting a lot of sound out of the back of those woofers righ...

Hi, Marcus
As I understand it is 15” loaded into 110-150Hz horn, MF compression driver in 350-400Hz horn, Ribbon tweeter and a pair of tapped horns? Looks good.
If it were up to me than I would paint the entire baffle with tweeter and MF i...

Jan ,I meant to say: when you get the real LF from playback then you might reevaluate your preferences to HF “wildness”. The wide dissipation is always a good idea but without LF the wide dissipation does not work properly. The LF “compiles” the wide...
|

The ribbons surely do lack "qualities", but we are talking about serious "HF" in this case, and who says real HF actually wants "qualities"? I really doubt that any "tweeter" that can do "stuff" can also do what the ribbon does best - in a class...

I finally set it up new Tannoy Red best Twitters. They are sealed irregular shape and purely themselves do not sound bad. They do not have the full range feeling as they had with passive radiator and had a typical red sound of late Autumn leaves....
|
|
Wow, Romy, what a fraught time! You seem to have (somehow) focused on your sound system and narrowed things down to a tweeter, or at least some viable way to add "color". While you were talking, I was thinking that your S2s actually go pretty high, m...

Just turned on the TV to put on some YouTube while preparing to belatedly give Macondo a cleanup and right there was your new video...lost 45mins of cleaning time though, and those Bass Cannons take a lot of cleaning!Turns out the Red 10" pair I purc...

This weekend if I have time I will be doing the testing of my driver deciding which one I will be using. The framework of testing will be the following: a single driver, closed at 150Hz first order, mounted in infinite baffle and working along with M...

[quote user="haralanov"] It is certainly very very important, but how many systems you have listened where you can not be able to recognize the HFs as disconnected part of the sound? I just wanted to ask if you have ever heard a system, where the...
|
|
Haralanov, let me know if you actually have something, otherwise I will continue with the Audaphon ribbon for the first round of the downward-pitching exercise. On the one hand, I wish I'd kept the Peerless 2" paper tweeters I had; on the other hand,...

Bud, perhaps it does makes sense to try the “dotizm” one again. I quite severely review my view on the way in wish I use tweeter. I still am trying to make T350 to work, let see what I end up with. Nowadays my T350 sitting in 3rd order crossover, it ...

AlohaWell, Martin does this as a labour of love, it's not his day job. They are fibreglass, and once he has constructed the mould, the manufacture is fairly straightforward, unlike say JLH's devices.So you are not paying for audiophile...

Your explanations make it fairly easy to understand both the problem and conceptual solution in your terms. It's the actual, mechanical solution that I have trouble with.Unless you can somehow alter/vary the application index&nbs...

It is commonly known about the relation between the ultra high frequencies and lowest frequencies. The extended reproduction of highest frequencies ”improves” the lowest octaves and makes perception more susceptible to bass. The phenomenon is well kn...

Zanon, you seem to feel that RTA has some intrinsic value. In any case, in terms of results, I think you already have a sense of where this is going. If you are bound to use your present speakers in a room you yourself deem too large for them, t...

In regular off the shelf hi-fi system , be it a total lack of LF in your speakers or the "pinch" of dome tweeters or the midrange mud. Romy like all of us throws money on the problem and he usually chooses well regarded and expensive solutions. The...
