[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 ...

Thanks, Scooter.I am glad to hear from someone so quickly.I've been an "audiophile" for only 10 years or so. With the Edgarhorns, I am currently using a Cyrus Brenneman integrated amp (KT100). I also have a Yamamoto custom 2A3 (single plates) w...

Thanks very much for your prompt, courteous and informative reply!My thought about the crossover design for the EdgarHorn was due to a number of things:1. This particular EdgarHorn is being sold to make way for a Cain & Cain speaker which i...

Yes, there are a lot of paths.I can see that many DIYers are very much stick on crossovers, changing capacitors, choosing slopes in digital filters - FIR or not FiR and so on.I know very experienced people who now say that with digital crossover he d...

[quote user="Kerry Brown"] A digital crossover with lower bit depth and sampling rate than the recordings it's processing won't deliver maximum sound quality; unfortunately my DEQX crossover is limited to 24/96 so it can't process hi-res digital ...

I still thinking about this ides of ultra sharp digital filtrations and for whatever reasons it fascinates me. It is not the I am consider to do anything with it – it is absolutely not needed for me – still I might like the idea as a topological solu...

[quote user="jessie.dazzle"] After observing a pair of AK151s operating in free air, though only lightly driven, I just don't see how they can possibly generate so much pressure, as the cone barely moves! [/quote]
Why shout they move? One of the ide...

Thanks, twogoodears. I do not particular care about the frequencies cut-offs as I do not know the ALE drivers. If I speak with the system owner in context of what you say then I would post 3 questions: 1) What specific limitation or shortcoming of...

Hi. Well the behringer belongs probably to the most famous and also to the worst quality wise. Sure the passive sound better...Id go with the learnings from the behringer and apply it in a clean xover, either active or passive or even digital - but n...

Confirming our concern about digital crossovers, by Harman international, the parent co. of DBX, today at 11am, and I will quote, "theoretically they compress the sound" and also I will quote, "it is a concern for live recording and not live sound". ...

Lost in Space? More like Spaced out.Taking Tramadol and Soma for a cervical problem. I listened to Art of the Portuguese Fado Guitar and everything was 3D.Kidding aside, I did some reading yesterday. Some online articles on the DEQX makes me want ...

Is there any abstract value to going for a preamp with a stronger output if you're using a passive xo at line level?I'd prefer to answer this question myself but i really don't have the budget to be swapping amps.How does a PLLXO interact with a non-...

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...

I played with this Behringer DEQ unit for a couple hours. What the magnificent machine would it be if all functionalities work! I mean they all work but they all make sound like shit, even this unit in hard-bypass sounds like shit and there is no oth...

Yep, it is a lot of work and it might look like not well organized work but there is good part in all of it – when you will be do you will be done and you would never do it again. Practice shows that those custom tailored systems are made and then us...

Today I had a promising experience. Bill is keep experimenting with his Dannoys and I was visiting him to see what's going on there, since I am still waiting for my panels and I can experience the Dannoy foreplay only valceruasly. We did a very usefu...

[quote user="twogoodears"]Yes, maybe the 120 db/octave is THE trick for complex multi-ways systems of highest resolution, yet this barbaric:-) slope can ONLY be achieved by digital domain crossovering... unfortunately, as a satisfied user of TacT RCS...

I think this is an interesting topic. I have made experiments (with a digital dsp processor) in my system and tried 4th order crossovers. I did not like the sound at all. Trying to explain this sound signature is tricky but here is my interpretation ...

I had a Walker Proscenium turntable with various cartridges. About twenty years ago I converted all my vinyl to 24/96 files and have never looked back. As far as dsp processing, the Trinnov altitude does a superb job of either recreating the hall sou...

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...

[quote user="outopos"]Hi Romy,I am new to your site. I have read some of your postings (including other sites) with much gusto.For the digital LP recording, I am (was) tempted to do the same, but given the fact that I have absolutely no personal ...

[quote user="scooter"] However, I had one very interesting observation living the "Class D;" plugged directly into the wall socket, they always sounded the same, regardless of day or time of day. That is the only audio gear I have ever encountered th...

My own experience suggests that it is possible to do speaker-level passive crossovers, but I must qualify that by saying that although I have put a lot into the crossovers themselves, and the wire,etc., etc., it has only been since I got the ML2...

Hi to everybody,I have used those caps: teflon V-caps, AN copper, Jensen copper, Siemens at the signal path of a tube power amplifier (300b SE) application. V-caps are technically very good, very clear, less microphonics, but missing s...

Putting The Mid Bass horns behind your head will not work. This thread was about Mid Bass Horns Project, do you thank you will be able to use any frequency above 80 cycles with rear fired horns that are behind your head? That is a Joke. It looks more...

[quote user="KS"]Thats the kind of stuff I was hoping for. I appreciate the help with this, there seems to be a scarcity of horn related discussion on the web and its proving hard to learn the ropes.One other unrelated question that could save me a l...

Thanks, Roman... I strangely (?!?) feel me like a schoolboy at his first primary schoolday... virtually ALL my (limited) audio knowledge, vanished... and I'm dealing with brand-new problems, like a crossover with fixed slopes and cut-off frequencies ...

Herman,
I am not familiar with your driver and I do not know those horns. It looks like they are 200Hz horns through….
You shall not worry about your horns create any shadow. As I understand you use digital crossovers with your horns and if...

[quote user="slack key"] As for audio problems, you are correct, I really have to sit back and think about what to do. Sure I want to improve what is now lacking.... soundstage, imaging and depth. As for the sound, of course, I like the sound o...

Thanks, jtavan.
It was educational. I made some first steps already. I made a slow 233MHz (and presumable it would have lower noise with lower speed) machine with no fans, and a large passive radiator on SPU. Formatted it and loaded Win2K Pro St4. S...
