[quote user="slowmotion"]I'm not so critical as you to open baffles for midbass, tho, in fact I think they can be made to work quite well, if one doesn't have the room for midbasshorns. [/quote]
You suggest that open baffles might be more successful...

The woofers need 2 be matched. What is the Resonance frequency of the cones of the woofers? You want to mount the woofers on front side of baffle or rear? Are you going 2 use dual 15 woofers on each side? Don't ruin your house by putting them in your...

I would start with the freq from 60 hz to 10 khz. If you already decided to use the Vitavox S2 and AK-151 get those and start using them in that range, it will take a long time to get them perfectly settled. Will you use the AK-151 inside a b...

Ok, the front baffle is ready. As I said the front baffle, the surface where the diverter will be attached, ingrated with the first section of the horn. You might judge the solidity if you wish – it is 5 layers of ¾ Baltic birch + 1 layer for front ...

HelloI've always wanted to try an ESL as a horn driver:So I employed a hi power Koss 3-layer bass module cut from Koss "model 2" spkr.Polarizing voltage was low on Koss design so it was upped to 3kv w/ custom PS.Horn is old closet that had a trapdoor...

Petar,I thought for along time how to reply to your post. All my thoughts basically narrow down to this. You're a soulful guy. There is nothing smart I can say to add or subtract to you findings but I think that the result you will finally get from y...

Back in the 90's i bought a pair of Aura 1808 woofers and made a set of 24 cubic foot corner enclosures 1 1/2 thick, crossover at 100hz, close to 300 pounds, way over built enclosure with a baffle on the face of the enclosure that i could remove. I T...

[quote user="Markus"]These speakers were not open baffle. I would agree with Mani's description of their sound, except for the 'edge' bit. That depended on where you were sitting/standing.[/quote]Then they would be baffle extenders which are not with...

I purchased a pair of front loaded horns with JBL e120 12" drivers. They are crossed over at 200 and 800Hz 24/octave2 pictures here:http://picasaweb.google.com/noviygera/Midbass#dimensions are of the cabs are 28" wide-20" high and 24" deep.When I ho...

[quote user="noviygera"]There seems to be a lack of useful feedback on the actual sound quality of these oddball, relatively rare TAD mids. So I think it would be helpful to share some basic observations I gather after listening to them for a couple ...

I am still here still trying to work it out. Read your mid bass horns article again. Learned a bit more. You right about open baffle I once foolishly sold everything I owned to buy a pair of km30. They never sounded good until one day...

Well, the first hurdle is matching efficiency from a dynamic driver to over-the-top horns like yours; but perhaps for others with somewhat lower efficiency horns...http://www.supravox.fr/anglais/haut_parleurs/285_GMF.htmI have had my eye on this one ...

Romy, Can you expand a little more on what the issue with dipole bass is and what it does incorrectly? I'm still not sure I know exactly what you mean (and I've had a look at some of your other comments on the site).What sonic aspects in particular? ...

This there is the last in the “THE PROBLEMS WITH HORNS” cycle. The previous threads might be found at:
Problems with horns: tweeters.Problems with horns: mid-range horns.Problems with horns: mid-range drivers.
This would be probably the most contro...

The more I think about the mode I am getting excited about the
direction the Remedies went. I see now how I can convert
the problem that I have with large inbound baffle into actual advantages. The
new plate will be probably 1.5”, heavy coupled an...

Jarek, why not China?
I did not particularly look in China, but I was looking for a person who whom I
can talk and who will be listening me and do what I asked. He did very good job
during the initial planning phase and I do like what he did in th...

Well, I do not like any
none-sealed enclosure. From my perspective IB box is also sealed and I am not against
it. It is not about the sealing of encloses but about absence of contra-phase feedback
that is always there in any other topologies. Ther...

I do not know how it goes for now. The Remedies is 4 boxes,
2 midbass sections and 2 to sections with Tannoys. I got juts one top section.
It is clearly that tops section needs to be redone. I presume that midbass sections
as well. I still have no...

Gargoyle, I have not made paper horns to amplify bass, but only to use as "wave guides", to +/- "shape" the sound. My results so far agree with Romy's theory, that the paper horns begin to eat energy when I used them "too low". In this case I used ...
|

Scott, I tend to think of IB in simple terms, basically, literally, as an "infinite baffle", the idea being that there is no load other than "open air" on either side of the driver diaphragm, and there is no "baffle step"/acoustic short between the t...

[quote user="anthony"]I have designed the 2 driver wood boxes and when I stack them and put them next to my horn stack in CAD they are just not as pretty as the steel tubes and actually detract from the aesthetics in my opinion. The main problem is ...

I realize the question as to how you will get mid-bass (horns vs other solutions) is still open.If you do go ahead with horns, you should be able to make them so that they'll accept most any 15" driver, which means you could use the horns in making t...

Romy, the drivers would NOT be facing down in a properly built infinite baffle. Google: infinite baffle subwoofer & then go to IMAGES to get a fast idea of installations. It is all extremely NOT complicated. The joists would not have to be cut...

Yes, for practical reasons, one side of an IB driver is usually "wrapped and sealed" to deliver lower frequencies from the other side, since it is generally impractical to actually make a baffle large enough to prevent sonic shorts. However, at high...

I realised this morning that I have done a "not-so-standard" thing in using leftover fibreglass batts for stuffing the tubes. The batts that I have on hand are high density batts, not the low density type of fibreglass that is usually used for stuff...

As I already have written before, I was looking at different bass solutions for frequencies below 110hz with my set-up. As of this weekend I have set-up a new solution and will be evaluating and fine tuning it for the coming days. The new bass sectio...

Wow! Did I ever stumble onto the right website.I've got enough reading here for a few lifetimes.Recently I cracked open a couple of speaker cabinets that I obtained years ago. Inside I found a Vitavox AK 121 woofer and a G.P. 1 horn unit, along wit...
