cardboard boxes? or enclosures? theres 8 or 9 enclosures hidden throughout my garage not including the horns :)

Are those the project horns found on their website? I planned on picking up a pair as well and build horns for them...

How much power will you be sending them? Be sure to give a review of them ;)

yeah, they're the "POWA" plans..Im gonna do some .25^3' sealed boxes for em as well.

They'll be powered by some bs reciever my g/f has until i get them shipped to my house :(

they look like *** right now, but they'll clean up nicely

That's a big *** compression chamber...really big. I guess that's what you need when horn loading drivers with as much Xmax as FR125's.

6mm is a hell of a lot for a 4.5" full range driver, considering Lowthers and Fostex's don't exceed 1mm...but then again, the FR's Qts is about 0.4 higher and far less sensitive :)

VERY impressive lowend output for a 4" driver. Needs alot of equalization though. Smooth and accurate, not overpowering. Im pretty happy with it so far.

not very good with reviews?

can you...explain further or share a set of plans?

JimJ
12-07-2005, 07:07 PM
Not as much as you'd think.

A pair of these: http://pic6.audiogon.com/i/c/f/1133143090.jpg 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 ;)

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 ;)

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 :)

thadman
12-07-2005, 07:22 PM
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 :)

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 :D

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.

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 :)

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
12-08-2005, 10:52 PM
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.

http://www.madisound.com/pdf/fostexcabs/103e_enclrev.pdf

Any ideas on this project?

The only problem is all dimensions are in metric......:mad:

looks like a fun build. speakers are cheap too :) worth a try imo

get a metric tape measure?...

ballstothewall
12-08-2005, 11:07 PM
And all the boards are .59" thickness!

JimJ
12-08-2005, 11:08 PM
FE103e's are a hell of a deal.

They do best in either horns or mass loaded TL's - stay away from regular bass reflexes, and definitely avoid sealed alignments.

JimJ
12-08-2005, 11:08 PM

Half inch stock will do.

ballstothewall
12-08-2005, 11:11 PM
Ok, so I can use 1/2" for that, good deal. Do I need deflex pads or somethin behind the speaker?

You mean the walnut? I don't know, dosen't matter...:up2somet:

We have a couple thousand board feet of 1"-1.5" in our wood shop!:veryhapp:

I can get that little amount needed donated to the cause.

JimJ
12-08-2005, 11:29 PM
Solid walnut? Pics are going to be needed afterwards :)

As for deflex pads, you'd probably want to be lining the compression chamber and horn flare with felt or something anyway...

ballstothewall
12-08-2005, 11:38 PM
If I have the time to do it right, solid walnut is a must, that stuff is BEAUTIFUL! So the part right behind the driver, and where it flares out to the room? How far back to I felt in the flare?

Thanks
