[quote user="haralanov"] Your midbass horns have delay with decay, because there are a lot of internal reflections (acoustic resonances) that takes some time to settle down below the treshold of hearing. It can not be compensated by "special type...

Just trying to put your own observations about the RI, etc. in some sort of context, Edgar, since the idea of "better" RI seasoning seems to be moot at present. As it happens, I actually like the general notion that "quality does not matter" for RI, ...

It wasn't the caps. The 12 inch drivers were both frozen solid after being stored in a dry basement for 30 years. Looks like the coils somehow fused to the magnets.Ordered a used pair from Japan for $300 with shipping and they arrived after 20 days i...

I had a similar setup with an IB subwoofer, 2x18" woofers, behind the listening area -- also time aligned. It's works ok. But it will excite the entire house structure if you play loud -- you can be sure. Everyone will feel it. But that's not the iss...

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 the tweeter was wire...

Antonio,
Bruce Edgar sells an excellent all front-loading horn system, the Titan, which works well in small rooms. He will sell you unfinished horns, and you can find/buy the drivers yourself if you are a DIY guy, or on a budget. Considering the...

Edgar, not sure how long you've been at FM, but there is an FM board here at GSC that sould give you some food for thought. As ever, some things stay the same, and other things have changed. For instance, analog has changed to digital, but the weirdn...

These were my first high end speakers purchased in 1980. They have been sitting in my basement for about 30 years as I've gone through everything from VMPS super tower 2 ar's to B&W 800 to my self built Edgar horns, which I’ve been using for abou...

I used to have Edgar 80hz straight horns and this was my only experience with short midbass horns. I did not like them in my system and sold them. Lately, I have been wondering about these designs in general and is there such a thing as a good soundi...

When I think back to some of the products made over the years I realize that neither we nor the manufacturers really know what makes something sound good. Some of the early pieces made by (and I hope Roman forgives me here) Pass, Van den Hul, C...

One more thing about the JBL 375, I did play around with them enough, I aligned the diaphragms several times untill they sounded their best and were very listenable, This was some time ago now, I didnt turn my horns then, so I tried them on the orig...

[quote user="rickmcinnis"]Is there a consistent effect from too large/too small and how is it analyzed?
Working on a new horn that I had turned by a fellow in Hungary and have made my back chamber so that I can easily manipulate the volume b...

[quote user="drdna"]Romy, I think you are asking if I have the Edgar subwoofers also. Yes, I do, like giant woodgrain refrigerator in the living room. So I do get some bass response. [/quote]

Edgar, thank you for sharing your findings. The timing couldn't have been better as I have just re-assembled my Dannoys after months of idling (I liked the sound of Dannoys so much that I decided to put a hard wood parquet to add some sparkle to ...

[quote user="noviygera"]I got this new midbass horn to replace the Edgar 80Hz straight horn. It is made by Funktion-One and they claim it plays down to 90hz. I could not get it to play below 120Hz and I am trying to figure out why.

[quote user="Edgar="]Not Amplitude. It's the rock solid phase linearity. It feels like a brick wall all the way up and down. I haven't looked at any graphs and haven't measured anything but that is my guess. There is no question of the great tone of ...

A “casual” look at full range usually results in 3 or 4 way playback for standard dynamic drivers or horns. There are a handful of “full range” commercial efforts from Edgar, Wilson, JBL, etc that are doing similar things with the range of each chann...

I have to admit I have no idea and did not experiment with matching horn loaded tweeter to big ,direct radiating "extended range' MF channel. I'm not sure it's doable. I was speculating on the reasons why the owner of Moscow instalation switched from...

I have used thick wool felt around the perimeter of my round horns at times. Having owned a pair of ROGERS LS3/5a's in my youth and being amazed at the huge sound those little speakers could effect one tries to re-use ideas. Diffraction control is ...

I appreciate the suggestions on the ceiling of the room; in my room the ceiling is about twelve feet tall and it opens on the side to another room with a taller skylight, so I do not know if this is a problem or not. It may be worth investigati...

These are 103db efficient 15" midbass boxes. It's a band pass horn design with narrow bandwidth of 60-250hz. No port thought, it's a sealed box with two chambers in front of the driver. I do not know how they sound but, myself interested in trying th...

Romy,You make very, very good points now I am re-evaluating this all-in-one horn concept. I do know one thing that I learned from my current system. Midbass horn that rolls off below 120 hz and integrated with sub is not good. I have struggled with t...
