Well, I would say this CES was very low on decent sound. Sometimes I had to fight with the urge to leave a room or two immediately after hearing a few bars of music being played.Still the hope is not lost. At a fringe show at the Flamingo hotel (THE ...

This weekend wife told me that I should not do nothing else
but to fix my playback and this was exactly what I wanted to do. Yesterday I took
good 14 hours to play with it, moving boxes, trying to find a good
configuration, making measurements, th...

While the aftermath of the midbass horn project is not over I am strategizing how I might implement Macondo’s LF section. The leading idea is to bolt a triangular shape sealed enclosure juts behind the small wall that cover the load bearing beam from...

I think we are all agreed that if time alignment and space were not issues, a bass horn would be the way to go.Now, I'm fairly convinced that the overwhelming benefit of horns in this range is the phase response, ie flat group delay vs frequency. Mos...

Hi miab, my room is approx. 6x5x4m, so although quite small by North American standards (not UK!), the ceiling is higher than that of most modern houses. This seems to play a big part in the LF performance of any speakers in this room. I currently ha...

[quote user="msaudio"]I Believe You made a mistake not useing a good horn maker. He is not bending long pieces of wood, he is putting a lot of straight small pieces to get away from forming long sides. Why is he not cutting long 1/16 inch slots along...

Stereo Lab, to whom Romy drew attention at the beginning of this thread, offer their products on Ebay at what seem to be reasonable prices. See here (http://stores.ebay.co.uk/Stereo-Lab)Looks like the small horns are made of artificial stone, whereas...

Unfortunately there was no further explanation, analyses, or a desire to look deeper (as usually on internet audio). [/quote]Glad you enjoyed the "Philosophy" section by Imai-san... some of his old writings deeply influe...

What I heard in your room on Saturday was superb reproduction of what was recorded from 40 Hz. up. This is ideal probably for a recording of a chamber group in a small hall without anybody present. One could hear the hall surroundings which replaced ...

The room is actually bigger now (about 75m2) but the whole orientation has changed. The speakers were at the opposite side of the room near the windows. Having windows for a front wall had a detrimental effect on sound in the old layout. The absorpti...

Macman, the “annoying peaks above the usable frequency range” is something that your specific installation might have in context of your room and your acoustic system location but it might not be a characteristic of tapped horns. I do feel ...

Is there a pill for that too? Seriously, it would be very interesting to hear what solution you come up with because I have converted from listening music solo to a small number of audience (friends). So much that I listen by myself much less oft...

I think the most room friendly and the most universal Danley speaker is the SM60. It has a 5 inch coax and two 8 inch bass speaker in a tricky molded horn, and small, light enough to use it with a standard telescopic pro speaker stand and keep it abo...

I think correct positioning the watt puppy and maxx model in room is not easy and each time i listened to them i sensed a bloated sound, I guessed bloated sound refer to acoustics. i know these model drivers are not fast but i guessed in a good room ...

Hello:I would like to ask this forum for advise.I picked up a very simple and cheap RTA and decided to use it to listen to my speakers. It is 1/3 octave RTA, so I know Romy will say it is useless. It may not be very useful, but I start with nothing s...

On July 4 I had a good listening session for a few hours. Not
frequently I have the luxury like this with 3 small kids. I was thinking critical
about the sound I was getting, even though the playback was deal cold after a 3
weeks not playing. To ...

Romy,You maybe thinking of your a/c problem backwards.
In use, air conditioning vents become louder as the air speed and turbulence increase. Reducing the aperture of a vent can increase noise because a reduced aperture increases air flow spee...

I've had a pair of PM4 and GOTO SG30W sitting by cupboard for several years now and instead of just watchinng the foam rot on the Lowthers, I was thinking of slapping the lot into a sealed box for fun. The PM4 would have it's own chamber of course.&n...

[quote user="drdna"]Looking again at the EdgarHorns, the placement in the room seems nearly optimal and they are now properly time aligned. Looking at the phase of the individual drivers and listening to each of them individually revealed that ...

Which are huge, they not even sound as the same orchestra into the same venue. I don't know if my computer rig, which I must use to play the 24/88 files, using a pair of SL600 into a very small room, would qualify themselves as a whole injection chan...

The frequency where your room turns into a pressure chamber changes the way that we perceive bass. This is how we get "bass" in a too small space like an automobile. When removing the ULF channel, all of the music is transmitted in a natural way for ...

I have heard vintage tannoy red (driven by 30w push pull EAR 861) and vintage tannoy gold (driven by 20w set ongaku japan). I think for 92db the 20w is not good idea.http://www.goodsoundclub.com/Forums/ShowPost.aspx?PageIndex=1&postID=3746#3746T...

romy, you said, you would place a 60hz midbass on the side, is this still your opinion? of, course i found no other solution in my small room. will do it the way you suggested, 60-300, 300-1000(thinking about gpa 288h(s2 is too expensive for me), may...

Well, it looks like you've somehow managed to just drop this "oops" box of yours in there and very neatly offset some main speaker small peaks and valleys, which is VERY interesting, if not the point...But my guess is that you would have to go way ov...

I, in my stupid imagination, thought that I will be able to close my R&E saga as I thought I found a truly wonderful new home for myself. The palace turned out to be grossly, I would say fraudulently, misspresented. Got home very disappointed an...

[quote user="jessie.dazzle"]It is interesting to note that the evaluation tool shows lines radiating perpendicular to the curve at any given point, just as the sound wave is supposed to be oriented as it progresses along the horns length. [/quot...

Collin,I would suggest that you abandon the idea of placing your speakers against the back wall with that reflecting/diffracting angle in front of the speaker(s). Such a structural intrusion would not be kind to the polar radiation pattern ...

Collin,I am pleased that you found my suggestions worthwhile.
I approached the issue of your music room with two questions in mind:1- How to avoid the structural angle from interfering with the sound2- Would an enlarged room be worthwhile...

Having a big window in front at night it becomes like a big mirror, some might get self conscious about it! JA The thing about glass is that it eats up bass and reflects highs like crazy, having said that, some of the best rooms I listened to, had...
