Romy, I re-read your comments a few times to better understand your feedback. I think you are saying the effects of my room may be dominating any problems with the Edgarhorn bass, or at least I can't know since I don't have any objective data. Is t...

I wonder how myth in all those digital gismos and how little what we considering in digital is obvious and self-explanatory in reality has not relation to Sound. Also, how much those people with who just learned how to solder and let their blind (and...

[quote user="speedysteve"]I have found
that 8th order X/O works best with them and I cross at 90Hz these days.
4th order is ok but you get minor colourations and some bleed through
that just aren't a distraction on 8th order. The bass horn takes ...

Last week I spent a few hours at the scene of NY’s Stereophile Show – HE 2004: a half-day on Thursday and 2 hours on Friday. As many other audio-shows it had many semi-ugly colorations, however as any audio shows this zoo trip brought it’s own “inter...

I have been running my new Ortofon SPU Mono cartridge and can’t figure out why SPU has such a strong positive reputation and why some SPU users when I ask them about Sound of those cartridge they roll up their eyes. Yes, it is all around fine cartrid...

Jessie, I have moved your post to your 45Hz horns thread but then decided to keep it here as some of my comments would be about entire system not only about your midbass horn. Anyhow, there is nothing there to laugh and it is pleasant to see that som...

de Charlus, this “are not afraid of cabinet resonance per se” is complicated subject. I have raised the topic in the “How to USE “Resonating Oops” in loudspeakers” thread:

Romy,

[quote user="CO"] Ive been building and improving my own speakers the last few years and at this point i'm thinking a fully horn loaded setup ( 3 way + sub ) is the best route to take to get a speaker capable of faithfully reproducing the elect...

Hello Romy!I just listened to this system http://www.hornfabrik-eder.de/index.htm which has an 8" Görlich in the upper bass horn and I couldn´t find anything "inherently faulty" about > 4" without compression. The kettledrums sounde...

Absolutely flat response will usually sound as you've described it; listen to your ears. If you are hearing the opening bass line of "So What" via the sub, you must be running the sub pretty high in frequency to compensate for lack of mid-bass. From ...

Got last night the last bass drivers for MiniMe’s bass sections and put them all together. Even thought I still have problems with MiniMe uppers channels (the Fostex F120A drivers are still hatching) but the bass sections turned out to be very good. ...

[quote user="Jorge"]Now if you design a TH for 70 hz, you can use it from 35 hz up to 140 hz, and that could match up to your 142hz front Upper Bass horn. With this solution you completely eliminate the need for a Folded horn midbass channel, that ...

YL 75000 has heavy phase plug indeed , rca style (see sketch) while 1250 ( I never had one) gets a fixed metal dome equivalent to spherical piece on 75000 and rca plugs without conical shape pointing the exit of throat. Ir...

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...

Interesting. I wonder whether I actually did the Pussy- or Wilson positioning.I found 4 tiny hotspots around the whole room (for one specific vertical position). The boom areas were large (or perhaps there were many boom areas, close together?),...

[quote user="jessie.dazzle"] This event really reinforces my curiosity to try such drivers in the Mid-Bass horns. As there are plenty here in Europe, that is exactly my plan (most however are not 16O... don't know to what extent that might be an issu...

Of course i used the 515-G. this famous speaker suited very well to our bass horn...as any other bass horn ! the only problem with the 515-G was a upper end a bit...noisy with our 6db crossover.When we started with Cyrille-audio a project of a 15" fo...

Romy, thank you very much for very detailed explanation of your horn theory.Let me present some doubts about it. From physics basics when we have more than one springs (suspension, throat resistance, back chamber) we can consider it as one spring. Th...

[quote user="jessie.dazzle"]As for balancing the amplitude between channels by driving them from different taps: I drive the upper bass horns form the 16 Ohm taps, and everything else from the 8 Ohm taps. An 8 Ohm versoin of the upper-bass driver...

I dont want to hack this thread into TH, I tried them with sub-amps 150 watts and they didnt sound good, but I was using a passive preamp, when I added an active preamp things started to get better, now with 12 watts and a a lot of gain, bass is ama...

OK, the new Macondo frame is over as well. Eventually after 6 years of learning how to make the damn horn speaker to sound good, after numerous incremental successes and failures, stupidity and brightness, moves to wrong direction and mistaken assess...

Hi Romy,I believe you're right and it's due to the amount of LF the vinyl outputs, which may be more than the Bidat or the tuner do. It doesn't happen with all the discs, just some of them, which happen to be old recordings that probably have mo...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...
