[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 ...

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...

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...

Well, I loved, loved it loved it… but today I decided to experiment with integration the new horn into the system and learned that it would be far much complicated and take more efforts. Below are 3 sweeps form listening position, Firs is the new hor...

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...

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 ...

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...

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 ...

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?),...
|

Yes, the topic is really interesting, at least to me. There is one thing
for sure – the man who starts the development of his acoustic system with a blank
sheet of paper, must have a lot of experience in arranging different channels
in terms of ps...

[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...

Ok, I have been experimenting with placement : Long wall versus short wall. Though the frames have wheels and roll very easily, my room is cursed with an elevated platform smack in the middle of everything (about 14 inches higher than the main floor)...

[quote user="decoud"]Since the 8M is now no longer to be had anywhere, for love or money (delighted to be contradicted on this), would people care to suggest alternatives for precisely the use Romy puts it to: driving a round, 3-4 inch throat, upper ...

I understand your point of view concerning 'vintage' in comparison to 'contemporary'. What I find the most troubling with many of the present/contemporary attempts in design is that many people claim to have a truly horn loaded system capable o...

I gave another run to Vitavox S2 with electromagnet and while I was listening I come across to an interesting observation. I screw the S3 in 330Hz horn and was trying to run it with 500Hz crossover point. It is pretty standard configuration, the way ...

It seems to me that any number of LF systems might be made to "work", once a few general questions have been addressed squarely and answered honestly, in order to have some significant empirical data to start with and direct progress, based on largel...
