Hi romy, mine are the 515-G drivers. I will be x-ing over at 600hz to Vitavox S2's (2nd order, yipes!). The S2s are in 320hz LeCleach horns. I was kind of hoping for just a general reply like when you guys look at a pictu...

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 met today with guy who is local woodworker and who looks like a right person to render my Midbass horn. He proposed something that I did not consider. He felt that the horn like mine might to be sliced by 2 inches increment, cut on 3-dimensional CN...

[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...

Lets look at it...http://home.planet.nl/~ulfman/"The
carlson is a broad band resonator" - hrm... It does ocour as
elegent solution on first looks but do you wnat a broard band
resonator coupled to the end of your midbass horn? This aside it doe...

My string quartet have just spent 6 days recording haydn and being assaulted by nasty Genlecs.
I can assure you that this is NOT what I want my system to sound like.
(Actually I sort of began to see the point of them after a while.. but
that's ano...

Dear Malinowski,
Here are the input data used in the HornResp simulation for the tractrix midbass.This is a 117cm long tractrix horn with the TD-1201. Throat area 84 cm2, mouth 10000cm2 with 5,6 liters back cavity.Ang: 1Pi; FTA 89,80; S1 84;...

[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...

I am more and more inclining to finish my horn in the textured paint of the color of my room. However, lately I have another “idee fixe”. My listening room has a very pleasant light pattern, something that was here before and something that I added. ...

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...

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?...
|
Herman, I am glad that you feel better about sound from your midbass horns. I do not know what damage digital amps incur but even your experience of hating the sound of those horns to falling in love with them just after changing the amp do suggests ...

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...

My work to make the Fane S 8m work, continues amd I have yet to hear my midbasshorn built perferctly according to Romy-specifications. I will continue because in early trials there was something I did like. I guess I will just end up with a measly €...

You said are lucky to get hornloading down to 150Hz. Then I guess you suggest you will end up at maybe 175Hz. Hornloading a compression driver down to 175Hz is not too difficult and the horn will not be larger than the Avantgarde Trio midbass horn, a...

This is probably the reason I can listen to EV Patrician IV in relatively small space and close to the speaker without much of fatigue. The other factor must be that it's 4- way design with narrow band-pass for each horn. EV T25 2" phenolic com...
|
One of the challenges I see for my midbass horns is to minimize hf output. The goal is to operate the horn in a bandwidth where it can cross to the higher horns, and have each horn function in their best sounding manner. My drivers are Altec 515-16...

Active sound cancellation has been used widely in industry as ANC (Active Noise Control)They work best and functional in narrow band bass FRQ. To make it short it is not practical in your case... Bass FRQ have enough power to vibrate horn mouth and c...

[quote user="Macman"]Just realised that I had dual highpass filters on the TH, which more or less cut off frequencies below 50Hz entirely. A lot better now, still much to be made of course.[/quote]
This is very normal. People get the “building...

[quote user="cv"] The acoustic transformation's probably done by the time the wave reaches the throat. [/quote]
Yes, it is. If we loom how the S2 internal channel done then it would clearly indicate the it should not be a great tweeter but wha...

A visitor of my site sent me email with following:
“I take it you don't like the Rogero style (or Johan Dreyer) bass horns with wings, but you could add compression to a similar setup and make it work properly. I have made several design...

hi romy!i opened the s2 some nights ago, to me it looked different, but i will check it again, maybe some reflections really fooled me. i searched your s2-guide very carefully, the one in your pic i would without doubt identify as a clear suspension....

[quote user="Jeffrey Jackson"] so, my straight horns... I like them very much.. I built mine similar in style to what Greg B linked, but obviously much smaller.. mine are just under eight feet long (length of a sheet of plywood) and have a mouth roug...

[quote user="haralanov"]Actually I see the biggest benefit (besides the huge sound body) in the fact that such a configuration allows very precise adjustment of the way how the harmonics of each UB channels touch the midrange, by simply dealing with...

martinshorn, I do not pay too much attention to K-hor as now as I do not pay too much attention to
Midbass channel. If I do not go for big ass midbass horn with large moth that
would change the whole room repose picture then to make a midbass chan...

Since I finalized how my midbass horn handles decay the only things left in my playback is to set the right level and cut off point of my ULF channel. Formerly I did set it up for 35Hz, second order and it was fine as a temporary setting. However in ...

Since I change the transformer I picked some harmonics and now I feel that my midbass has a bit too long roll off. I moved the second low pass filter close to the first filter. After a very careful listening and some thinking I ended up with setting ...
