When you set in your chair looking and listening 2 your sound system you are trying to create in your mind and your ears the illusion of instruments placement on the stage in front of you, to make it more lifelike and real. So you putting horns behin...

I have built quite a few bass horns and found any thing over 1/2 inch ply wood reinforced is all you need, in front of your baffle. If you had ever built a few on your own and had the right equipment to test you would realize this, but when your a ha...

Romy,I say "Go for it"! With your usual documentation, we can only profit from you getting the hernia first. I got mine operated on last week, so looking is all that I can do for the next 3 months.One thing that has always roused my curiosity: your ...

I need to say that for whatever reasons the midbass horns acts as a phenomenal tranquilizing sedative to listen some older recordings. The midbass horns make bad sound much more palatable and make attention to be much less distracted to quality of ...

I had the same problem with my 6 foot, bass horns , which were built from 3/4 inch high density fiberboard. On doing some measurements back then, it turned out that they were vibrating for a few milliseconds after a pulse, giving a decent rise time b...

Decoud,Thanks for your comments.Regarding Modular horns : Below is an image of what I originally had in mind for the mid bass horns.40Hz cutoff / 8" throat / flare length 3mI pulled this image from the jd project thread, so some here will have alread...

... my only experience with newer, expensive Berillium diaphragm Goto drivers, has been a mix between "Wow, I'm listening to a +35K euros speakers system" and... "Gosh, music do not sound this way"... this of course was due to some crossovers tuning ...

Haven't yet seen a camel here. I don't believe they are indigenous to the region. It's challenging being away from home, but no carnal thoughts of animals - yet.bty, my interest in this thread is motivated by solving the same problem. I need to fi...

Romy, My Bidat being extremely sensitive to incoming electricity and now with Purepower in my mix I am getting to know my Bidat in a new light. I did think I had a grasp of what the Bidat could and couldn't do but feeding it through Purepower it has ...

Room is extra nice, better then most i have seen on the web. We all will hear from you telling us there is no bass, in your new room. It looks like 300Hz down will suffer because square footage increase like 10 fold from last room. You will have much...

I thought the closer you got to the corners of the room the more floor support you would have in a given room, with sub flooring, your floor joists are going into blocks on the edge of your house so that would be the most support for Macondos, we...

Ok, I think it is a good time to deal with room acoustics. All infrastructure problems are set. The Midbass horns are underway; the electricity will be investigated but as now is addressed by PP2000. Macondo and Milqs are inhaled, the system is up. I...

I will be dubiuos about the slanted enclosure if not done properly, all drivers must be time aligned and since they are playing the same frequency, deficiencies in time alignment become more obvious. I made a slanted enclosure but with the drivers ...
|
|
I tried a highly modded DEQX on my horns for some time, we did all the time alignment with it, we used 1st order and 4th order xovers and everything in between, we used LeCleach adjustment for bass and all the other drivers we had it sounding for som...

[quote user="Horn Savant"] I think it's about the same as free-air resonance - backwave to entire basement. Precedent: pre-war theatre horns(open rear like Shearer/ERPI)(unlike post-war reflex tuned designs like Altec A4)(I don't like reflex boxes - ...

Hey Romy I read your requirements of a mid bass horn. I am using jabo tratrix KH-55A(320hz) with altec 288 and I want the mid bass to go under that. I would use a trattix round midbass if it was possible. But it's just not with in my abilitys to buil...

Just new to this forum and there is so much to absorb.. One post I read suggested that horns be constructedwith dimensions to suit 1 oct. below the lowest Freq. to be used. I know that Mr. Le Cleache favours this ashe says the group delay is bette...

It is hard to get used to the idea of 1 or 3 LF channels supporting a "stereo" hi-fi. But the way it winds up working is that the "wrong number" of channels, or sources in the "wrong spots" can make things sound worse, because of cancellation an...

[quote user="oxric"] In my mind, and given my specific circumstances, the question of strategy is inextricably tied to the resources in terms of time, efforts and funds that I will be able to devote to this attempt to achieve what I have in mind ...

[quote user="Romy the Cat"]The biggest problem that usually people face when they listen the middbas horn is that people tend to make the middbas horns too short. In the short horn the driver shot right through the horn and the LF go not “get loaded”...

[quote user="skushino"] • total horn length (incl. back chamber) shall not exceed 1,00m • the horn shall have conical approximation of a hyperbolic flare contur with m=0.6 • the horn shall have a 5/16 mouth size of a free space horn •&...

I never was fan of the Oris 150. They meant be used with Lowther type of drivers, that never worked properly. The Oris 150’s upper bass is not really the bass that might be obtained form the Oris’ mouth. Should this Oris has twice smaller throat and ...

http://www.webbtjanst.se/lenco/loudspeakers.asp shows some photos of unfinished horns. Comments on mouse-over.The 250Hz horns are probably not super optimal since I'm crossing over at, I think, around 1600Hz right now. Yes, the little horns...

I wish I could pin-point the frequencies and explain the effect better. I'll do my best.I want to cover my ears when a Pavarotti sings certain higher notes or some notes when Caballet sings pretty "comfortably".It's like bad PA horns or horrible acou...

As far as I remember the former presentations in the latest version there is less softening by the amps without sacrificing tonal neutrality and the digitally controlled bass section has less problems with the room. Mr. Martion always plays a very br...

[quote user="RonyWeissman"] I have the 515-Gs If I remember correctly, and I am trying to find suggestions on what is proper horn-loaded cabinet still. And I agree my tannoy golds so far have worked best with early 70's mcintosh 22...

[quote user="Jorge"] Lets just say that TH bass is much cleaner and generates a different "bass sensation" in the room. Once you get used to it, it is very difficult to go back to boxed bass.I find the sound similar to what a Mid bass horn woud pla...

Hello Romy, thank you for the answers. Your horns have a round mouth, but their profile is not spherical. That is the profile of the Avantgarde Horns you formely had - apparentyl you have anayzed them intensively, could you elaborate what problems yo...

Hi Jeff,I am certain that the best midbass was NEVER in a corner horn. Every fold in the horn is a new resonance. Corner horns need many folds...In addition, if you are very "anal retentive" about phase alignment - how do you integrate a corner horn?...
