Ev hp 9040 drivers#
With midbass drivers of your choice you can make a conical Synergy type horn of your desired 60° x 40° dispersion. Reducing from 2" to 1.4" exit allows for wider HF dispersion, and a close physical location to the midbass in a Synergy style horn, they can be located within 1/4 wavelength, allowing a single point source from around 100 Hz to 16 kHz, and will have pattern control to around 400 Hz, or lower depending on the mouth size chosen. Heat up the snout adapter bolts with a torch to loosen the Locktite- I broke off one of the bolts before I figured that out.

Remove the snout adapter, now the driver has a 1.4" exit (same as the DH1AMT drivers I use in my PA). Sounds like you already have midbass horns, but my suggestion using the DH1 would be this: I figured the rather geometric shape of the mantaray-like HPXXXX would be a design that I could actually manufacture.ĭo you have any suggestions? I am looking for a not too wide dispersion, something along the lines of 60° horizontal and 40° vertical.Ĭlick to expand.Great drivers, I evaluated several lighter "modern" drivers and none were better. So I was looking into ways of building flares and trying to find other projects, which was not easy, since, like you pointed out, not many people would be too interested to DIY such a type of horn. They rarely pop up overseas and if they do, people also ask ridiculous prices. I am not US-based and importing something like those EV horns or of course JBL 2360 / 2365 would be pointless when considering the shipping cost. Below those midbass horns play up until 500 and not higher. It is not meant for domestic use, it is rather going to be an experimental array that should be as directive as possible. The reason I am interested in these is that I need a pair of flares that should not only load from 500Hz up, but also be directive right from 500Hz. I was not too sure if the drawings were true to scale or not. I asked about the dimensions of the slit to gain better understanding of the proportions of this family of horns.
I understand that it is rather uncommon in "near field" applications and what you say makes sense. I've seen "some" pictures of these in home environments and figured "someone" might be using these still.
Hi Art, your in-depth comment is much appreciated! Thanks a lot. What specific purpose do you need the slot dimensions for? If you are planning to duplicate the horns, the dimensions you ask for are just a start, there are nifty little vanes in the transition area from round throat to the rectangular radial diffraction slot.
The diffraction slot is around an inch wide on both horns, the vertical arc measurement is fairly accurate and can be scaled from the drawings. These horns were not popular with DIY folks back in the 1980s when they came out, the only ones I sold back then were the smaller format units.īy the time the HR9040 came out, cone midrange had made the large format horns unpopular other than for large scale sound reinforcement in reverberant environments.Īlthough the EV horns have smoother transitions than the Manta Ray, they still have the same problems, and diffraction horns are generally not high on the approval scale for current "Hi Fi" use. Hardly noticeable in our opinion.Click to expand.The few remaining horns of this type are more likely to be found hanging in a church or arena than in a living room, and if they are in someone's living room, they probably went through the DIY phase decades ago and are not looking at these pages with any regularity, if at all.
