Reading my old post about my new R&E adventures
Midbass Horns and Real Estate
http://www.romythecat.com/LatestPosts.aspx?ThreadID=11190
….and contemplating on my prospective move to a big room I am strategizing what change...

Hi Paul,Could you help me understand what you mean?Are you saying that even without a high-pass filter, a <8" driver has an imbalance of 'harmonic development' above and below 150Hz... and that this is not the case above and below 400Hz?If we ...

I think the first basic positioning for Macondo is found. The MF island is well extended in the room – the mouth of the Upperbass is at 90 from the back wall. The playback dose quite well and do demonstrate a lot of potentials to take is further. No...

[quote user="Lbjefferies7"]I will be laughing my ass off when I visit the GoodSoundClub website and read about a certain Cat who was finally motivated into tuning the ports on the Mini's specifically to "adjust" Macondo's sound! I am reminded of...

Here is a picture of my upperbass horn’s back chamber. The actual chamber is approximately twice smaller as it patched internally with construction foam (a wonderful John Hasqiun invention). The dust cap of the driver is where the weight is hangs dow...

I do not think is has anything to do with parametric equalizer or writing own curves, at least I have no interest in it. The immediate questions that I would like to have answered are following: 1) Can Macondo or elements of Macondo produce ANY sound...

[quote user="George"] I am not quite understanding part of what you say:
"It is very difficult to make a generalization about it but generally this quite “large bloomy space” will be a space equal to, I would say, 1/8-1/12 of the room ...

[quote user="Rewind"] The drivers we use may be superior or inferior. As long as mine are the best I could possibly afford I can relax. I do love horns, and I can probably find quite a few errors in my signal path. If they are there the horns will am...

I’m not convinced at this point that it is good – I need to see it more in context of everything else - but the initial results are very promising. What I do now, I keep the compression Fane 8M in horn but I very dramatically increase dumping of it...

Adrian,
This it truly complicated question. The Titans’ upperbass (the better one, curved, with 12” driver) is not realty HF capable and it makes a MF driver need to go all the way down to probably 500Hz (I do not know what Bruce dies in the crossov...

I know Antonio, pay attention that since the Synopses get rig of HF nose then the upperbass and the lower mid harmonics opened up with totally different presentation. If I were some kind of industry dealer and make my living by shepherding the Morons...

Zanon, at this point I do not think about specific of amplification. I more care about the transducer per location ratio and a filtration in context of it in order to get the “filling schema” of the room properly. The quality of the powerful amp will...

[quote user="haralanov"]Vasyachkin,in the context of your question, there is a very big difference between bass driver loaded with slow and fast expanding horn contours.[/quote]perhaps. but since i don't know much about horns i can't follow what you...

Thank, Manolis, it did address some concerns. I think I even know what you did with the MF driver. You were able to get 50Hz out of this looks like horn? This is impressive. The boundaries-loaded horns sometimes allow doing away with the horn siz...

I think hearing loss has to do a little bit with excessive HF in todays loudspeakers, with age this is the freq. that is mainly lost, so boosting it a little bit helps that... Most commercial systems exagerate HF mainly to make you think they have...

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...

The mean KOTriode in his thread “A different breed of 6C33C amplifier“ jinxed me with his 6C33C vulnerability and today my output tube at right midbass channel went down. The characteristic pings, which via the midbass horn sound like house room is c...

Paul,I have not heard the synergy horn or any speaker with that design. Here is what I am talking about:http://www.yorkville.com/images/products/u15_cut_sm.jpgIn this particular case there are 3 mids and 1 tweeter driver sharing the same horn.This so...

I am sorry there is a mistake in my previous post, anyone who has played around with a dedicated channel for a 40 to 200 hz frequency know hat the only sound coming out is a wooo, woo, woo... Not much to do listening test by, we can measure, but te...

[quote user="ayebee"] The horns that Stereo Lab make are very good, especially considering the relatively modest prices. I bought the "Ultra-Fi" version of the 140Hz horns and they are of course not completely free of resonance ….Present system consi...

[quote user="tuga"] As for the "Grande Castine", I think that the MF section is in fact the MF/LF section and the frame is indeed curved.[/quote] If this speaker does not use any complimentary LF section then they drive the woofers at let say 40Hz. A...

Keith,
Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a w...

Romy, you said there is no proper tone. In your old system/room setup you were very close to the back wall, but now it is far behind you. I'm probably wrong, but I think you don't have proper sound in the mid-upperbass with this configuration which ...

[quote user="Vasyachkin"]the only real questionable aspect here is adding a second set of back firing, inverted phase horns. mathematically speaking it is what the design "needs" but of course the real question is - what does it sound like ? that's...
