I mean,
does anyone really expect to straight away come up with a "horn
profile" via math (or voodoo) and then just turn or cast it, bolt on
the driver and, voila?If we talking about upper-bass horn I think yes, via match.I reade...

[quote user="Merlin"]Well firstly on those, the tweeter is not offset to one side - it appears to be time aligned directly behind the midrange horn and upper bass unit. Secondly, that's a JBL 2405.[/quote]I do not know which driver the Living Voce us...

[quote user="Dresden"]I'm a new reader of your website and one subject which interests me a lot is that of upper bass horns.

[quote user="Romy the Cat"]As I said above your you "experienced today with GOTO" is just your transitional

It seems like I should just abandon the idea of using the Druids... and trying to get some sort of coherent integration with my WB-Chimeras (acting as the lower- and upper-bass units)... and running the whole hodgepodge with totally different amplifi...

[quote user="chaos"]anything wrong with a square mouth on the midbass (or should it it be in a special width/height ratio)? would give me the right height of upper mr when i go 4way....[/quote]

MoreartDouble-driver "back horns"? I am not sure what you are asking about, or what exactly you are promoting, but I do not agree with lightweight, square-section horns, because I have never heard one that worked, apart from shifting certain frequen...

I'm also of the opinion that the bass is one of the most critical and most challenging parts of playback. Not talking about quantity, but rather the quality of bass reproduction. My approach has been to split the bass in two parts - Low and...

Romy,It is interesting that you say that the problem is well known. I discovered this application in 1972, while trying to come to a solution for the sonic insults being supplied by a pair of Ohm F speakers. I eventually got them to act somewhat as W...

Dominik, Jessie is right - it is irrelevant the precession of your profile if you horn does not go to high into HF. The LF gain of upperbass horn happens in the first half of horn anyhow. I do not insists that I am right but I have a hypothesis that ...

I spent some time with my back chamber, trying to drive the driver resonance heighted. I built a sealed sarcophagus as a back chamber (if somebody are interested I can post a picture) approximately 1.5 gallons but it moved Fs for 700Hz. Then I began...

None of the commercial speakers might relay on the Imbedded principles because the obvious reasons. They always look for as neutral as possible location because they mostly designed for anechoic operation. However, if the Imbedded techniques are used...

[quote user="skushino"]My desire is to use a pair of bass horns for each channel, both vertically oriented, one each exhausting to the floor and the ceiling. I have an idea that spatial presentation will gain a big boost with both up and down firing...

[quote user="Romy the Cat"]My right bass channel that that sited right next to the equipment bay has no bass. The left LF channel is sitting in a very good “hot” spot but the right is in bass hole. I would need 6-8dB of extra gain across the ent...

In reference to the two (or three) prototypes, the base design contains one (1) driver, a second proposal to the base design uses two (2) drivers (using almost the same exact enclosure--an increase of volume/area in the chamber containing the two [2]...

Hello all,Some time ago, I bought a pair of very early production ML2s for an ongoing horn project (see "Note at end").Rather than just let the ML2s sit and wait for the horns to get done, I of course tried them out with my "normal" 89db/watt@1m spea...

Now that the preliminary excitement of my ingenious idea wore off, I'm ready to share it and accept the harsh reality of any shortcomings... but seriously.
For a while now, I've been been working on optimally integrating my 3 channel...

It is also possible that I'm reacting to a lack of true dedicated mid-bass. As previously mentioned, while the pair of 40Hz horns are under constructon, I co...

[quote user="noviygera"]And one last thing for now I'd like to ask you. Would you know of a builder in the USA that can design the horn based on my requirements so that I do not attempt to be a horn designer? I can get the design built locally.[/...

Well, I screw-in today the S2 with filed-coil into my horn. I decided to drive it with 2.4A. I used a regulated DC PS and did not employ my prepared for this tusk 4.2 Farad capacitor: the voltage is too high for my cap. The current gave me a ni...
