I have an opinion, admittedly "based" on only a few personal experiences, that basement rooms are very good for developing low bass response. It has something to do with the absolute rigidity of the majority of the room boundaries, again just in my ...

hi all,thanks for your interest !yes the frame is curved, HF and MF are //yes there is a phase plug in the bass horn. This cover 80-300Hz.there is a separate infra-bass section, covering 20-80Hz.images of the bass phase plug and the infra-bass sectio...

[quote user="Markus"]Re-reading, I realise you stated your preference for a sealed bass array only in relation to Dreyer's bass horn, not to bass horns in general.[/quote]Markus, it is not only about the Dreyer's bass horn. It is about lower bass...

Hi everybody, after reading RomytheCat's Macondo Setup I am very impressed ( phantastic music room ...) . Presently I have no working horns ( they are boxed), just questions.

I have no experience with bass horns, but I suppose that any sound source into a given size room can excite its modes, hence a big bass horn or a line array of boxed woofers can be equally annoying in that regard. So if the idea of using horns is to ...

Dave Glackin interviewed Dr. Bruce Edgar in his home, prior to the 1996 WCES. A follow-up on the speak...

[quote user="slowmotion"]I don't understand what you mean here, Romy? To me "live" bass ( like when listening to an orchestra ) is much more dynamic than any reproduced bass I've ever heard. Also if listening to a real contrabass in a normal listenin...

First off, I forgot to mention an interesting observation: Before running the sweeps (previous post), since the drivers in the upper-bass horns are new, I decided to verify/optimize rear chamber volume (they are easily adjustable)... I wasn't expecti...

[quote user="Romy the Cat"]
The bass traps, the biggest one, have only limited effectiveness on the spectra of interest and usually have much more effectiveness in 2-3 octave above the spectra of interest. This make bass to sound less problematic b...

[quote user="noviygera"] Vasyachkin, if this is still relevant:I've tried dipole bass and dipole mids with horns mid/highs in my system. If anything, dipole works the WORST for the bass and here's why:It does not load the room with bass pressure (or ...

[quote user="jessie.dazzle"] Assuming you go ahead with the mid-bass horn project: If you decide to run the woofer towers along with the mid-bass horns, it is logical to assume they'll produce much of the range produced by these new horns. [/quot...

[quote user="Vasyachkin"]has anybody tried a horn speaker with a dipole bass section ?[/quote]Well, I must say that I have tried dipole bass in a few configurations, including dipole bass plus horn, however I think this is completely immaterial to th...

Here we go, I will be telling you that I am looking or that I have found the “best” cable to use for bass channel? Sound like a stupid thing to tell you and sound like a stupid thing to read at my site. Still, I will be obnoxious enough to insist...

I guess I have found a more or less usable new configuration for ULF channel. It is 28Hz, second order, with slightly raised ULF on the transition slope. It sounds quite good. Well, I am not supposed to say this. It doesn’t sound good but it sound pr...

I was taking lately with the Blue Angel’s Andre and kept asking him about his cartridge’s bass. He got “scared” and asked me if I am looking for overly-anaphased bass, then he asked what kind music I am listening. I perfectly understand why he got “s...

You and I now have what seems to be very similar situations; similar MF and HF channels, in a room of similar size. However, I still have no operational dedicated mid-bass channels; you do. I have dedicated lower-bass channels; you do not. As is ...

Actually a Tapped Horn would be bigger than a sealed enclosure, here is one of my first TH tests. The sound is very different than the sound coming form a Sealed encolsure. My first impression was that the bass was gone! There was no bass sensati...

A few days back a local audio guy come to my place, heard some music and I played and said something that did not expect from his level of audio intelligence. (I wonder if it was the same guy who advised me to write a handbook “How to make friend...

[quote user="guy sergeant"]One issue that I would consider is that the Tractrix profile supposedly does not lend itself aswell to extremely low frequency horns (being too short) as other profiles in particular the Hypex (Salmon) shape. [/quote]
Yep,...

I have today a local audio guy stop by at my place for some listening. He never was in my new place and was curios what have done with my new room and my new installation; he was in my old room. When I asked him to criticize what he heard he mention ...

Actually I got interest in the idea of having remote control attenuator on my ULF amplifier, I juts need to find a company who will be able to do it for me. For whatever reasons audio people feel bass channels have to have an attenuator. This is alwa...

[quote user="Romy the Cat"]The mid bass and lower bass are fine, the lower bass is another subject. It is there and it is goo but I would like to have more. It is not that it is deficient but… put in this way if it has more than my playback will be a...

[quote user="Romy the Cat"] The major minor thing remains to find different lower bass. I said “minor” thing as my lower bass is not bad, in fact I do insist that it is very proper lower bass as I did set it up lately properly…..Despite that I in...

The lower bass configuration in my room is a bit interesting below is the bass diagram (under 50Hz)
As you can see the allocation of hot bass sports is superbly favorable in the room. There is pretty much no bass anywhere in the ...

Since I do not do SACD and stay in PCM world I always wonder what the optimum sampling rate might be. As I told I discard the 48X as never was necessary rate. So, we have 44.1K, 88.2K, 176K and 352K… Surely we are out of 16-bit world – a move f...

I was recently reading a book called "The Cyclist's Training Bible" by Joe Friel. The author immediately surprised me by not being an idiot. Anyway one of the things he said is that the SCIENCE of training / exercise physiology is USUALLY ONE STEP ...
