Horns *pics*

Not as much as you'd think.

A pair of these:

sold on Audiogon, with drivers, for $300.

But of course, there are horns in the 100-104dB range that do sell for $500 and above with no speakers, so it's all relative //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'm curious that you got good results with it, because at least looking at the specs of the FR125, it seems better suited for a mass loaded TL or Voight Pipe than horn loading. But those are some excellent results //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

The bearing on one the router bits froze up and pretty much ruined the other enclosure. Like the performance enough to build one over again //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

do they have horns in the 108-110dB range? I have a full workshop (including a lathe to work with) and my uncle owns a CNC company. I wouldnt be buying one, this would be a project.

http://www.passdiy.com would be the place to go, I think the Kleinhorn is around that.

The highest efficiency commercially-built horn I know of is the Klipsch La Scala, @ 104dB/W. 110dB/W is possible, but you need a ton of room, not just because the cabinets are huge but also because you a lot of room between you and the speakers. Otherwise, amplified hum can drive you nuts //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

thast freakin nuts...

How much of an increase of the low-end would I see? Is it possible to build bookshelf horns with at least 100dB efficiency?

Sure, if your bookshelf could fit in the Library of Congress //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

Horns take space, no way around it...besides, a bookshelf is about the worst place you could mount a speaker. Kills room gain.

The easiest (from a construction, not finance standpoint) is going with a line array...but once you start to increase driver cost, things get substantially more expensive that way. Hence thylantyr's work with really cheap drivers.

jez that looks like my intestinal track

 

[thadman 10+ year member]

they wouldnt be placed in a bookshelf...theyd be placed on my desk or next to my tv. I would like to build some 4 foot HT horns and some ~2 foot Horns for a computer setup.

Would I see a large increase in low-end output with the horn design (thats what is most desirable to me)?

Horns that small are possible (see the Japanese ones I posted a pic of)...but generally, you get better performance as mouth size and compression chamber size gets more optimal (read: huge).

You would see a big increase in low end, that's part of the allure of horn loading //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Jack or Inhuman, would it be possible if I could get a copy of those plans (of the pics you posted w/ the crazy horns) I'm pretty sure I might be albe to wrangle some cheap CNC time, possibly free.

*edit* and what driver those are made for also...

css fr125.

Inhuman used CSS FR125's...http://www.creativesound.ca

But Fostex and Lowther are other brands of drivers that do well in horns.

 

[ballstothewall 10+ year member]

Those 125's are a little to expensive for my tastes.

Have you heard anything about the FE103E's?

I really want to make a horn, and the plans for them look pretty good, tuned to 50hz, so it goes low enough I can use my RE 12" for a sub.

Any ideas on this project?

The only problem is all dimensions are in metric......//content.invisioncic.com/y282845/emoticons/mad.gif.c18f003ab0ef8a0d9c27ca78d77a6392.gif
